preferred namespace prefix: sstim
preferred namespace uri: https://w3id.org/sstim#
in dataset: void
prior version: https://w3id.org/sstim/0.17.0
version info: 0.18.0-dev
history note: 0.4.0 — added left/right laterality body placements, quantitative stimulus datatype properties (frequency, flicker rate, beat frequency, duty cycle, gain, phase), the ExposureLimit class with quantified optical/flicker/hearing safety boundaries citing external standards, and the affordsDeliveryMedium capability-to-medium relation. Grounds the Sensory Field interface (ADR 0011).
history note: 0.4.1 — added the sstim-ex: to sstim-v: perceived-modality/sensory-channel closeMatch bridge and the somatosensory/haptic/tactile/vibrotactile convention scope notes (ADR 0019, P5.5). Released as part of SSTIM 0.5.0. Additive; no terms removed or renamed.
history note: 0.6.0 adds structured caution severity and action metadata, self-report phases, explicit SKOS inverse links, and stronger operational definitions while retaining every 0.5.0 term IRI.
history note: 0.6.0 narrows mappings that had conflated SSTIM's domain with brainwave-entrainment or therapy concepts, removes an unverified Music Ontology association, records the corrected MeSH audit, removes obsolete OBI_0000011, and limits OBI protocol alignment to the actual SSTIM protocol class.
history note: 0.6.0 — completes operational definitions for every exposure concept, materializes SKOS inverse links for non-reasoning clients, adds precise union domains and scalar cardinalities, and strengthens exposure SHACL coverage. Additive at the term level.
history note: 0.7.0 adds orthogonal evidence-basis, proposition, scope, search, source-governance, review, and ecosystem relationship/purpose/outcome controlled values. Legacy overloaded evidence tags remain deprecated for compatibility.
history note: 0.7.0 — ADR 0031 replaces the initial flat agent-level relationship and consent surface with qualified relationship, membership, implementation-responsibility, and engagement records; the approved public graph is current-state while complete operational history is private and append-only. The original ADR 0024 properties remain deprecated for migration only. 2026-07-19 — ADR 0032 adds sstim-eco:publicationStatus as a second, backward-compatible admission basis: a relationship may be admitted to the public graph at any truthful non-approved status (e.g. notified) so the person it describes can review it in context before consenting; the person-consent gate on a claimed publicationStatus of outcomePublicationApproved is unchanged.
history note: Initial exposure module for post-0.3.0 ontology work. The module does not assert physiological or health effects directly; those statements must be modeled as qualified claims with evidence or knowledge status.
history note: The 2026-08-08 Wikidata review adds a conservative close match for monaural beats and weakens the binaural-beats technique mapping because Wikidata Q863539 also represents a perceptual phenomenon and music genre.
history note: Tranche 1 of the reviewed external mapping pass, 2026-09-05, adds 57 mappings to MeSH descriptors, UBERON anatomical classes and Wikidata items across techniques, neural phenomena, neural systems and neural target sites, and brings the module from two external vocabularies to four. Every target was dereferenced at its own authority; the evidence, the rejected candidates and the predicate reasoning are in docs/ontology/ALIGNMENT_CANDIDATES.md.
history note: Tranche 2, 2026-09-06, maps 23 delivery media to MeSH physical-agent descriptors and Wikidata physics concepts, and is the first tranche to reach the exposure namespace, which the module now declares as a dependency. Where a scope note settles containment the row says so rather than defaulting to closeMatch: MeSH Light spans visible, ultraviolet and infrared and is broader than this vocabulary's visible-light medium, while MeSH Sound is the audible band and is contained by its acoustic energy. Eleven media in the same scheme stay unmapped, and two exact-label candidates were rejected as ablative or as a measurement.
history note: Tranche 3, 2026-09-07, adds 17 Wikidata mappings across signal shapes, audio noise colours and study designs. Wikidata carries it alone because MeSH's study-design descriptors are publication types, describing an article rather than the design of the study it reports, which is what this vocabulary classifies. Two rows deliberately avoid a better-matching label: shapeNoise takes the signal-processing sense rather than noise as unwanted sound, and shapeEnvelope the waveform envelope rather than the stationery item.

evidence notes
type: AnnotationProperty
definition: Internal human-readable note on evidence basis and caveats. Not for user-facing display.

modified at
type: AnnotationProperty
definition: Timestamp attached to a mutable annotation record when it was last edited. Ontology and evidence resources should use dct:modified and PROV-O for publication provenance.
range: dateTime

modified by

definition: Identifier attached to a mutable annotation record for the actor that last edited it. Published RDF should use prov:wasAttributedTo for agent provenance.

assesses proposition
type: ObjectProperty
type: FunctionalProperty
range: Assessment Proposition
definition: Links an evidence assessment to the single atomic bounded proposition it evaluates.

basis comparator
type: ObjectProperty
range: Comparator Descriptor
definition: A comparator the basis source used, as source-level metadata.

basis intervention
type: ObjectProperty
range: Class
  union of: Stimulation Intervention
  union of: Stimulation Protocol
  union of: Stimulation Technique
  union of: Exposure Profile
definition: The studied technique, protocol, intervention, or exposure profile this basis source is about (for example paced breathing rather than an auditory cue).

basis modality applicability
type: ObjectProperty
range: Modality Applicability
definition: How sensory modality applies to this basis source: mixed, unknown/not reported, or not applicable.

basis observed effect direction
type: ObjectProperty
range: Effect Direction
definition: The direction of an outcome the basis source reports, as source-level metadata.

basis observed outcome
type: ObjectProperty
range: Evidence Outcome Concept
definition: An outcome concept the basis source reports on, as source-level metadata distinct from the assessment proposition.

basis sensory modality
type: ObjectProperty
range: Sensory Modality
definition: A canonical sensory modality the basis source explicitly supports. Zero modalities requires an explicit modality-applicability value.

basis source
type: ObjectProperty
type: FunctionalProperty
range: Class
  union of: Bibliographic Reference
  union of: Evidence Search Record
  union of: Governed Research Output
definition: The single source of a qualified evidence basis: a bibliographic reference, a governed research output, or an evidence search record.

basis study design
type: ObjectProperty
range: Study Design
definition: The design of the underlying studies contributing to this basis source.

basis study model
type: ObjectProperty
range: Study Model
definition: The model or stage of this basis source's findings (human, preclinical animal, in vitro, computational).

basis study population
type: ObjectProperty
range: Population Descriptor
definition: The identified population studied by this basis source.

basis synthesis type
type: ObjectProperty
range: Evidence Synthesis Type
definition: The synthesis level of this basis source (primary study, narrative review, systematic review, meta-analysis, literature review, tutorial).

cites reference
type: ObjectProperty
domain: Evidence Claim
range: Bibliographic Reference
definition: Links an evidence assessment to a bibliographic reference. For every bibliographic basis source the assessment carries a matching citesReference triple (ADR 0027); publication clearance is a separate concern (ADR 0029).

composed of
type: ObjectProperty
domain: Preset
range: Voice
definition: Links a preset to its 1–6 voice specifications.

composed of track
type: ObjectProperty
domain: Preset
range: Track
definition: Links an engine configuration to the layers it is composed of. Distinct from sstim:composedOf, which links a BSC catalog preset to its voices: a configuration whose schema has generic layers uses this, one whose schema has the four catalog voice types uses that.

conflict disclosure
type: ObjectProperty
range: Conflict Disclosure
definition: A conflict-of-interest disclosure record attached to an independence determination, including the explicit no-conflict-declared record.

custodian
type: ObjectProperty
type: FunctionalProperty
range: Agent
definition: The agent that owns or is custodian of a governed research output.

defined by framework
type: ObjectProperty
domain: protocol
range: Sensory Stimulation Framework
definition: Links a protocol to the broader framework that defines or constrains it. The domain is the general OBI protocol class, not a stimulation protocol: a capability-boundary or baseline protocol can be authored and constrained by a framework without thereby becoming stimulation (ADR 0034 §7).

defines technique
type: ObjectProperty
domain: Sensory Stimulation Framework
range: Sensory Stimulation Technique
definition: Links a sensory stimulation framework to a technique that it defines or governs.

derived from
type: ObjectProperty
type: AsymmetricProperty
type: IrreflexiveProperty
domain: Preset
range: Preset
definition: Links a preset to its immediate predecessor preset version. The relation is directional, asymmetric, and not transitive; use repeated links to traverse a longer revision history.

describes stimulation
type: ObjectProperty
domain: Stimulus Specification
range: Stimulation
definition: Links a specification, which is an information artifact, to the stimulation process it describes.

disables track
type: ObjectProperty
domain: Session Specification
range: Track
definition: A layer of the configuration that this session turns off — a soundscape left out, an ambience muted. Listing what was disabled keeps the configuration itself unmodified, so the same preset remains comparable across sessions that used it differently.

evaluates subject
type: ObjectProperty
range: Class
  union of: Preset
  union of: Stimulation Technique
definition: Links an evidence assessment to the preset or technique it evaluates. Neutral: the assessment's direction lives exclusively in hasClaimDirection. Replaces the directionally misleading supportsRelation.

follows protocol
type: ObjectProperty
domain: Preset
range: Sensory Stimulation Protocol
definition: Links a preset to the sensory stimulation protocol whose rules or constraints it follows.

for implementation
type: ObjectProperty
type: FunctionalProperty
domain: Preset
range: Sensory Stimulation Implementation
definition: Links a preset to the implementation whose parameter model it configures.

domain: Caution Tag
range: Caution Severity
definition: Assigns exactly one interface-priority severity category to a caution tag.

has caution tag
type: ObjectProperty
domain: Preset
range: Caution Tag
definition: Links a preset to a safety or usage advisory flag. A preset may carry zero or more caution tags.

has changed parameter
type: ObjectProperty
type: FunctionalProperty
domain: Session Event
range: Stimulation Parameter Kind
definition: Identifies which delivery quantity an event changed, for the events that change one: a parameter the participant or protocol altered mid-session, and a value a safety boundary constrained.
scope note: Only for discrete changes that the record cannot otherwise recover. A modulation declared in the specification — a breathing period gliding from one value to another over a stated transition — is already fully described there, and restating it as events would create a second source able to disagree with the first.

has claim direction
type: ObjectProperty
type: FunctionalProperty
domain: Evidence Claim
range: Claim Direction
definition: Whether the cited evidence supports, is mixed on, is inconclusive about, or refutes the asserted relation.

has delivery modality
type: ObjectProperty
domain: Sensory Stimulation Intervention
range: Sensory Modality
definition: Links an executed sensory stimulation intervention to one or more broad controlled modality categories engaged by its delivery. Use the exposure module for channel-level physical-medium and perceived-modality detail.

has effect direction (deprecated)
type: ObjectProperty
type: FunctionalProperty
range: Effect Direction
deprecated: true
definition: Deprecated ADR 0027: observed effect direction is source-level metadata; use sstim:basisObservedEffectDirection on the qualified evidence basis. Appears only in the generated non-authoritative 0.7 compatibility view.

has event type
type: ObjectProperty
type: FunctionalProperty
domain: Session Event
range: Session Event Type
definition: Identifies the single controlled category of an observed session event.

has evidence basis
type: ObjectProperty
range: Evidence Basis
definition: Links an evidence assessment to a qualified basis. Every assessment has at least one.

has evidence tier
type: ObjectProperty
type: FunctionalProperty
domain: Evidence Claim
range: Evidence Tier Value
definition: Links an evidence claim to its strength classification tier, accounting for study quality and modality matching.

has experience category
type: ObjectProperty
type: FunctionalProperty
domain: Unwanted Experience Observation
range: Unwanted Experience Category
definition: Identifies the single controlled category describing this experience.

has independence determination
type: ObjectProperty
type: FunctionalProperty
range: Independence Determination
definition: The policy-based independence determination of a review decision. External relationship never implies independence.

has instrument
type: ObjectProperty
type: FunctionalProperty
domain: Self-Report
range: Observation Instrument
definition: Identifies the single versioned instrument that produced this report's observations.

has intended effect
type: ObjectProperty
domain: Preset
range: Intended Effect
definition: Links a preset to one or more controlled design-intent categories. The relation describes purpose and does not assert that the effect occurred.

has modality tag (deprecated)
type: ObjectProperty
range: Evidence Modality Tag (deprecated)
deprecated: true
definition: Deprecated ADR 0027: the tag mixed sensory modality with study model and synthesis type. Authoritative data uses the orthogonal basis axes (basisSensoryModality, basisModalityApplicability, basisStudyModel, basisSynthesisType, basisIntervention). Appears only in the generated non-authoritative 0.7 compatibility view; removed no earlier than 1.0.

has observation
type: ObjectProperty
domain: Self-Report
range: Participant Observation
definition: Links a self-report to the qualified observations collected in it.

has observation role
type: ObjectProperty
type: FunctionalProperty
domain: Participant Observation
range: Observation Role
definition: Identifies the single thing this observation observes.

has onset phase
type: ObjectProperty
type: FunctionalProperty
domain: Unwanted Experience Observation
range: Experience Onset Phase
definition: Locates when this experience began relative to the session.

has perceived relatedness
type: ObjectProperty
type: FunctionalProperty
domain: Unwanted Experience Observation
range: Perceived Relatedness
definition: Records whether the participant perceived this experience as connected to the session.
editorial note: A perception, not a finding. No query, export, or aggregation may read this as an attribution of cause.

has persistence
type: ObjectProperty
type: FunctionalProperty
domain: Unwanted Experience Observation
range: Experience Persistence
definition: Records how long the experience persisted, as a controlled category.

has proposition form
type: ObjectProperty
type: FunctionalProperty
range: Evidence Proposition Form
definition: The single controlled logical form of an assessment proposition.

has public claim level
type: ObjectProperty
type: FunctionalProperty
domain: Preset
range: Public Claim Level
definition: Links a preset to the highest public-facing claim level its user-facing copy uses. The legality constraint (PresetShape, ADR 0018) checks that supporting evidence meets the level's required tier.

has rendering mechanism
type: ObjectProperty
type: FunctionalProperty
domain: Signal Rendering
range: Rendering Mechanism
definition: How the rendering produces the signal in this channel: amplitude modulation of a carrier, a binaural or monaural beat, direct presentation.

has rendering presence
type: ObjectProperty
type: FunctionalProperty
domain: Signal Rendering
range: Rendering Presence
definition: Whether this rendering puts the signal physically into the world or produces it perceptually. Required on every rendering, because evidence does not transfer freely between the two.

has report phase
type: ObjectProperty
type: FunctionalProperty
domain: Self-Report
range: Self-Report Phase
definition: Identifies the single collection phase of a session-associated self-report.

has reported severity
type: ObjectProperty
type: FunctionalProperty
domain: Unwanted Experience Observation
range: Reported Severity
definition: Records how severe the participant said this experience was.

has reproducibility level
type: ObjectProperty
type: FunctionalProperty
domain: Session Specification
range: Reproducibility Level
definition: States which reproduction claim this specification supports. Required to be stated rather than assumed: this class's own definition promises fully determined output, which is a stronger claim than a specification alone can honour when the engine is not pinned.

has resolution state
type: ObjectProperty
type: FunctionalProperty
domain: Unwanted Experience Observation
range: Experience Resolution
definition: Records the state the experience reached.

has response action
type: ObjectProperty
type: FunctionalProperty
domain: Unwanted Experience Observation
range: Experience Response Action
definition: Records what the participant did in response.

has response state
type: ObjectProperty
type: FunctionalProperty
domain: Participant Observation
range: Response State
definition: States why this observation does or does not carry a value. Required on every observation: an observation whose absence of value is unexplained cannot be interpreted or aggregated safely.

has review decision
type: ObjectProperty
type: FunctionalProperty
range: Review Decision Value
definition: The outcome of a review decision: confirm, request revision, or reject.

has review status (deprecated)
type: ObjectProperty
type: FunctionalProperty
range: Review Status
deprecated: true
definition: Deprecated ADR 0027: review state is derived from immutable EvidenceReviewDecision records, not stored as a mutable status. A non-authoritative 0.7 compatibility view may derive it; it is excluded from validation and authorization.

has reviewer relationship
type: ObjectProperty
type: FunctionalProperty
range: Reviewer Relationship
definition: The reviewer's relationship to the assessed work: self, same organization, external, or unknown.

has self-report
type: ObjectProperty
domain: Session Instance
range: Self-Report
definition: Links a session instance to zero or more consent-governed self-reports collected at explicit phases. Multiple reports support pre/post and follow-up observations without overwriting prior data.

has session event
type: ObjectProperty
domain: Session Instance
range: Session Event
definition: Links a recorded execution to the occurrences observed during it. Order is carried by each event's offset rather than by the order of these statements, because an RDF graph has no statement order.

has signal
type: ObjectProperty
domain: Stimulus Specification
range: Stimulation Signal
definition: Links a stimulus specification to a signal it describes. A specification may carry several, and several channels may render the same one.

has signal rendering
type: ObjectProperty
domain: Stimulus Channel
range: Signal Rendering
definition: Links a stimulus channel to a rendering it presents.

has signal shape
type: ObjectProperty
type: FunctionalProperty
domain: Stimulation Signal
range: Signal Shape
definition: The form of the signal: a periodic shape, an envelope, noise, or a sampled recording.

has source governance record
type: ObjectProperty
type: FunctionalProperty
range: Source Governance Record
definition: Links a governed research output to its single immutable source-governance record.

has stimulation target
type: ObjectProperty
domain: Class
  union of: Session Specification
  union of: Stimulus Specification
range: Class
  union of: BFO_0000029
  union of: BFO_0000040
definition: What the stimulation is directed at: a person, a non-human animal, a plant, an object or material, or a place. Absence is meaningful and permitted — a stimulation characterised as present in unoccupied space has no target.
scope note: Deliberately broad. SSTIM describes sensory stimulation wherever it is applied, and restricting the target to humans would exclude animal work, plant and material studies, and the characterisation of an environment independently of who is in it. Being a target carries no claim that the target perceives, responds, or benefits.

has stimulus channel
type: ObjectProperty
domain: Stimulus Specification
range: Stimulus Channel
definition: Links a specification to a channel through which stimulation reaches the subject.

has stimulus temporal structure
type: ObjectProperty
domain: Stimulation Technique
range: Stimulus Temporal Structure
definition: Links a stimulation technique to one or more controlled descriptions of its temporal organization, such as periodic, quasi-periodic, aperiodic, adaptive, continuous, pulsed, or scheduled administration.

has timing authority
type: ObjectProperty
type: FunctionalProperty
domain: Session Instance
range: Timing Authority
definition: Identifies the single timing surface whose readings produced this execution's clock origin and event offsets.

has typical frequency band
type: ObjectProperty
domain: Neural Oscillation Type
range: Frequency Band
definition: Links a named neural oscillation to the conventional Hz ambit by which it is usually delimited. The ambit is a measurement convention rather than a boundary of the phenomenon: see sstim:extendedHzMin and sstim:extendedHzMax for the wider range the rhythm is reported to occupy.

implements framework
type: ObjectProperty
domain: Sensory Stimulation Implementation
range: Sensory Stimulation Framework
definition: Links an implementation to the framework it realizes.

implements protocol
type: ObjectProperty
domain: Sensory Stimulation Implementation
range: Sensory Stimulation Protocol
definition: Links an implementation to a protocol it realizes.

implies presence
type: ObjectProperty
type: FunctionalProperty
domain: Rendering Mechanism
range: Rendering Presence
definition: The presence a mechanism necessarily produces. Whether a signal physically reaches the subject or is constructed by the nervous system is a fact about the mechanism, not a choice a curator makes per rendering: amplitude modulation puts a real modulation into the world and a binaural beat never does.
scope note: Stated on the mechanism so a rendering names only its mechanism and the presence follows, which is the pattern sstim:requiresEvidenceTierRank uses on claim levels. sstim:hasRenderingPresence may still be asserted, and a SHACL constraint rejects any rendering whose stated presence contradicts its mechanism.

in group
type: ObjectProperty
type: FunctionalProperty
domain: Preset
range: Preset Group
definition: Links a preset to its group classification. Each preset belongs to exactly one group.

incorporates technique
type: ObjectProperty
domain: Sensory Stimulation Framework
range: Sensory Stimulation Technique
definition: Links a sensory stimulation framework to a pre-existing, vendor-neutral technique that it uses but did not originate. Distinct from sstim:definesTechnique, which is reserved for techniques the framework itself defines or governs; a framework that merely applies binaural beats or photic driving incorporates them rather than defining them.

independence policy
type: ObjectProperty
type: FunctionalProperty
definition: The named policy whose criteria an independence determination applied. Required for independent and not-independent determinations.

intended neural phenomenon
type: ObjectProperty
range: Neural Phenomenon
definition: Links a stimulation process, technique, protocol, or intervention to the functional neural phenomenon it is intended to affect. Records target intention, not an observed result.

intended neural system
type: ObjectProperty
range: Neural System
definition: Links a stimulation process, technique, protocol, or intervention to the distributed neural system it is intended to engage. Independent of the entry route: targeting the auditory system does not imply entering through it.

intended neural target site
type: ObjectProperty
range: Neural Target Site
definition: Links a stimulation process, technique, protocol, or intervention to the broad nervous-system site it is intended to engage. Records target intention, never delivered dose or observed effect.

mechanism neural access route
type: ObjectProperty
domain: Stimulation Mechanism
range: Neural Access Route
definition: Tags a proposed mechanism with the neural access route it invokes. Hypothesis metadata: it never reclassifies the technique that proposes the mechanism.

mechanism neural phenomenon
type: ObjectProperty
domain: Stimulation Mechanism
range: Neural Phenomenon
definition: Tags a proposed mechanism with the functional neural phenomenon it invokes. Hypothesis metadata.

mechanism neural system
type: ObjectProperty
domain: Stimulation Mechanism
range: Neural System
definition: Tags a proposed mechanism with the distributed neural system it invokes. Hypothesis metadata.

mechanism neural target site
type: ObjectProperty
domain: Stimulation Mechanism
range: Neural Target Site
definition: Tags a proposed mechanism with the neural site it invokes. Hypothesis metadata, distinct from a technique's intended target and from an evaluated outcome.

neural access route
type: ObjectProperty
range: Neural Access Route
definition: Links a stimulation process, technique, protocol, intervention, or stimulus channel to the biological route through which its neural target is intended to be engaged. In a multi-channel exposure profile the channel-level binding is authoritative and the coarse value must be backed by it.

outcome neural access route
type: ObjectProperty
domain: Evidence Outcome Concept
range: Neural Access Route
definition: Tags an evidence outcome concept with the neural access route the finding is about. This is how a demonstrated route that competes with a technique's declared intended route is recorded without altering that declaration.

outcome neural phenomenon
type: ObjectProperty
domain: Evidence Outcome Concept
range: Neural Phenomenon
definition: Tags an evidence outcome concept with the functional neural phenomenon the finding is about. This is the join that makes evidence about neural effects queryable across techniques and routes.

outcome neural system
type: ObjectProperty
domain: Evidence Outcome Concept
range: Neural System
definition: Tags an evidence outcome concept with the distributed neural system the finding is about.

outcome neural target site
type: ObjectProperty
domain: Evidence Outcome Concept
range: Neural Target Site
definition: Tags an evidence outcome concept with the neural site the finding is about, which may differ from the intended target site of the technique assessed.

participant engagement mode
type: ObjectProperty
range: Participant Engagement Mode
definition: Links a stimulation or neuromodulation process, technique, or protocol to the degree and kind of active participation it requires of the individual. Not functional: a method with distinct phases may declare more than one mode. Records what the method demands of the participant, never whether the participation is effective.

primary frequency band
type: ObjectProperty
sub property of: targets frequency band
type: FunctionalProperty
domain: Preset
range: Frequency Band
definition: The single primary band among a preset's sstim:targetsFrequencyBand values, when more than one is declared. Corrects the former convention of an implicit 'first entry is primary' ordering, which RDF property values do not carry (RDF-08, 2026-07-24 audit).

proposed mechanism
type: ObjectProperty
domain: Stimulation Technique
range: Stimulation Mechanism
definition: Links a stimulation technique to a controlled mechanism category proposed to explain a response. The relation records a hypothesis or evidence interpretation, not proof of causation.

proposition outcome
type: ObjectProperty
type: FunctionalProperty
range: Evidence Outcome Concept
definition: The single identified outcome concept an assessment proposition is about.

proposition subject
type: ObjectProperty
type: FunctionalProperty
range: Class
  union of: Preset
  union of: Stimulation Technique
definition: The single subject of an assessment proposition; must match the assessment's evaluatesSubject value.

references preset
type: ObjectProperty
type: FunctionalProperty
domain: Session Specification
range: Preset
definition: Links a session specification to the preset it executes.

renders onto parameter
type: ObjectProperty
type: FunctionalProperty
domain: Signal Rendering
range: Renderable Parameter
definition: The parameter the signal drives — amplitude, frequency, luminance, spatial position, vibration intensity. This is also how one layer modulates another: a breathing signal driving spatial position is a rendering onto that parameter, not a separate mechanism.

renders signal
type: ObjectProperty
type: FunctionalProperty
domain: Signal Rendering
range: Stimulation Signal
definition: The single signal this rendering delivers. Two renderings naming one signal are the assertion that two channels deliver the same thing.

reports unwanted experience
type: ObjectProperty
domain: Participant Observation
range: Unwanted Experience Observation
definition: Links the observation that asked about unwanted experiences to the experiences the participant described. The asking is an observation with its own response state, so a report that asked and got nothing remains distinguishable from one that never asked.

review rubric
type: ObjectProperty
type: FunctionalProperty
definition: The immutable rubric or policy revision a review decision was made under.

reviews assessment
type: ObjectProperty
type: FunctionalProperty
range: Evidence Assessment Claim
definition: The single assessment revision an evidence review decision is about; must equal the revision its generating review activity used.

scope comparator
type: ObjectProperty
range: Class
  union of: Comparator Descriptor
  union of: Scope Marker
definition: The identified comparison condition of the proposition scope, or an explicit marker.

scope intervention or context
type: ObjectProperty
range: Class
  union of: Preset
  union of: Scope Marker
  union of: Stimulation Intervention
  union of: Stimulation Protocol
  union of: Stimulation Technique
  union of: Experiment Context
  union of: Exposure Profile
definition: The identified intervention, technique, protocol, context, or exposure profile the proposition scope covers, or an explicit marker.

scope population or model
type: ObjectProperty
range: Class
  union of: Population Descriptor
  union of: Scope Marker
  union of: Study Model
definition: A named population descriptor or study model of the proposition scope, or an explicit marker.

scope sensory modality
type: ObjectProperty

  union of: Scope Marker
  union of: Sensory Modality
definition: A named sensory modality of the proposition scope, or an explicit unknown / not-reported / not-applicable marker.

signal covers band
type: ObjectProperty
domain: Stimulation Signal
range: Frequency Band
definition: The signal's frequency extent contains the whole of this named band — broadband noise covering theta, for instance. The converse of signalWithinBand, and the reason the signal/band relation is an interval relation rather than membership.

signal overlaps band
type: ObjectProperty
domain: Stimulation Signal
range: Frequency Band
definition: The signal's frequency extent and the band intersect, with neither containing the other. Recorded rather than inferred, because a partial overlap is a design decision worth stating.

signal source asset
type: ObjectProperty
type: FunctionalProperty
domain: Stimulation Signal
range: information content entity
definition: The recorded material a sampled signal is taken from — a violin note, a voice, rainfall. Required when the shape is sampled and meaningless otherwise: a sampled signal is only reproducible if the sample is identified.

signal within band
type: ObjectProperty
domain: Stimulation Signal
range: Frequency Band
definition: The signal's whole frequency extent lies inside this named band. A point signal such as 10 Hz within alpha is the ordinary case.

specified by
type: ObjectProperty
domain: Preset
range: Stimulus Specification
definition: Links an engine configuration to the stimulus specification it realises.
scope note: Many presets may realise one specification; that is the point, and it is what makes cross-engine comparison possible. The link is asserted by whoever measured or derived it and is never inferred: what stimulus a preset produces depends on the engine, the transducer and the listening conditions, so entailing it would reintroduce exactly the engine-dependence this layer exists to escape.

stimulation delivery approach
type: ObjectProperty
range: Stimulation Delivery Approach
definition: Links a stimulation process, technique, protocol, or intervention to a coarse operational description of how the input is introduced or the interface positioned. Values are non-exclusive and may be combined.

supports relation (deprecated)
type: ObjectProperty
sub property of: evaluates subject
range: Class
  union of: Preset
  union of: Stimulation Technique
deprecated: true
definition: Deprecated ADR 0027: the property name encodes a supporting direction the claim may not have. Use sstim:evaluatesSubject; direction lives exclusively in hasClaimDirection. Retained as a materialized compatibility alias during 0.7.x; removed no earlier than 1.0.
history note: Deprecated 2026-07-13 in favour of sstim:evaluatesSubject (ADR 0027); original range decision from ADR 0013 is preserved on the replacement.

targets frequency band
type: ObjectProperty
domain: Preset
range: Frequency Band
definition: Links a preset to 1–2 target frequency bands. RDF property values are unordered; use sstim:primaryFrequencyBand to identify which one is primary (RDF-08, 2026-07-24 audit).

technique modality
type: ObjectProperty
domain: Sensory Stimulation Technique
range: Sensory Modality
definition: Coarse legacy/convenience relation linking a sensory stimulation technique to broad sensory modality tags. Use the SSTIM exposure module when physical delivery medium, perceived modality, device capability, body placement, experiment context, or knowledge status must be represented separately.
scope note: Kept unchanged for compatibility with SSTIM 0.3.0 consumers. New detailed modeling should use sstim-exposure.ttl terms such as sstim-ex:deliveryMedium, sstim-ex:perceivedModality, and sstim-ex:requiresDeviceCapability.

range: Session Specification
definition: Links a recorded session execution to the single immutable session specification it realizes.

uses technique
type: ObjectProperty
domain: Stimulation Protocol

expertise area
type: ObjectProperty
domain: Ecosystem agent
range: Concept
is replaced by: has ecosystem relationship
deprecated: true
definition: Links an ecosystem agent to SSTIM controlled concepts (modalities, mechanisms, techniques) it works on. A sourced claim about scope, not an assertion of rank or authority.

range: Ecosystem relationship type
definition: Assigns one controlled relationship type to one qualified ecosystem relationship record.

publication status
type: ObjectProperty
domain: Ecosystem relationship
range: Engagement outcome
definition: The current lifecycle status of a qualified ecosystem relationship — one controlled outcome (e.g. notification sent, consent granted, publication approved) matching the engagementOutcome of the relationship's chronologically most recent engagement activity. Introduced by ADR 0032 as a second, explicit admission basis for the public ecosystem graph: a relationship may be admitted with any truthful status via this property, not only a final publication-approved one, so that the person or organization it describes — and anyone else — can see exactly where the relationship stands, including its context, without waiting for approval to become visible at all. Only a publicationStatus of outcomePublicationApproved for a relationship whose agent is a person still requires that person's own prior consent or self-publication; every other status requires no consent to display, precisely because it does not claim confirmation. A relationship admitted through the legacy path (ending in a PublicationDecisionActivity with no explicit publicationStatus) is treated as approved for backward compatibility.

type: ObjectProperty
domain: Ecosystem agent
is replaced by: relationship target
deprecated: true
definition: Links an ecosystem agent to the specific SSTIM resource it relates to (a technique, the framework, a reference, the community group, the platform), when applicable.

applies boundary
type: ObjectProperty
range: Class

applies to placement
type: ObjectProperty
domain: Exposure Limit
range: Body Placement
definition: Links an exposure limit to the body or near-body placement it applies to, since limits differ by site (for example eyes are more vulnerable than hands to optical radiation).

channel role
type: ObjectProperty
domain: Stimulus Channel
range: Stimulus Channel Role
definition: Links a stimulus channel to the role it plays in the exposure. Deliberate co-stimulation is not concomitant: two or more causal channels may each be intended.

characteristic delivery medium
type: ObjectProperty
domain: Stimulation Technique
range: Physical Delivery Medium
definition: Links a stimulation technique to a physical energy, material, or chemical agent characteristic of the method. It does not describe an executed dose or imply perception or effect; use an exposure profile for channel-level delivery.

concerns effect dimension
type: ObjectProperty
range: Effect Dimension
definition: Links a hypothesis, research question, design objective, or planned-outcome specification to the comfort, risk, perception, or physiological dimension it concerns. Carries no OWL domain (ADR 0027): allowed subjects are enforced in SHACL so use on a non-evidence statement cannot re-infer the deprecated ExposureEffectClaim.

range: Standard
definition: Links an exposure limit to the external standard, guideline, or recommendation it is derived from.

definition: Links an exposure profile, stimulus channel, or capability to a body or near-body placement.

has boundary applicability
type: ObjectProperty
range: Boundary Applicability Statement
definition: Links an exposure profile or stimulus channel to a qualified boundary-applicability statement. Direct hasComfortBoundary / hasExposureLimit links remain valid structural shortcuts; the qualified statement carries the rationale.

has comfort boundary
type: ObjectProperty
domain: Class
  union of: Exposure Profile
  union of: Stimulus Channel

range: Exposure Profile
definition: Links a protocol, technique, represented stimulation process or intervention, preset, or experiment instance to a structured exposure profile.

has hypothesis
type: ObjectProperty
range: Exposure Hypothesis
definition: Links an exposure profile or protocol to a stated hypothesis. Optional: a delivery-only profile states none, and generators must never fabricate one.

has knowledge status
type: ObjectProperty
range: Knowledge Status
definition: Links a protocol, exposure profile, channel, device capability, statement role, or knowledge-status assertion to a controlled SSTIM/BSC Lab knowledge or capability status value. Carries no OWL domain (ADR 0027, KR-05): SHACL enforces allowed subjects, admitting the DeviceCapability use promised here and preventing status links from re-inferring evidence semantics.

has knowledge status assertion
type: ObjectProperty
range: Knowledge Status Assertion
definition: Links a preset, technique, protocol, exposure profile, or stimulus channel to a scoped, dated knowledge-status assertion about it. Each assertion has exactly one incoming subject link.

access classification
type: DatatypeProperty
type: FunctionalProperty
range: string
definition: The access classification of a governed research output (for example private, shared-research, de-identified, public).

actual duration (seconds)
type: DatatypeProperty
type: FunctionalProperty
domain: Session Instance
range: integer
definition: Observed playback duration of a recorded session instance in whole seconds.
scope note: Whole seconds deliberately, where sstim:deliveredDurationSeconds beside it is a decimal. Elapsed time is observed once at the end of a session and second granularity is all a recorder can honestly claim; delivered time accumulates fractional segments and is exact. The coarser side is therefore the observed one, which is the opposite of the usual intuition and is why it is written down here. It has a consequence: the SHACL constraint holding delivered <= elapsed can be violated by rounding alone, by less than one second, with no real overrun — so a producer must round elapsed UP rather than to nearest. src/session/sessionRecorder.js does, and did not at first, which is how this was found.

affected population
type: DatatypeProperty
domain: Caution Tag
range: string
definition: Conservative plain-language description of the users or contexts to which a caution is especially relevant; not a diagnostic classification.

caution severity rank
type: DatatypeProperty
type: FunctionalProperty

definition: Ordinal rank used to sort caution severities from informational (1) through high-priority stop or avoid guidance (4).

channel duration (s)
type: DatatypeProperty
type: FunctionalProperty

channel frequency (Hz)
type: DatatypeProperty

type: DatatypeProperty
type: FunctionalProperty
domain: Session Instance
range: decimal
definition: The timing context's own reading at the moment the session instance opened. Together with each event offset it reconstructs the exact timing-context reading of every occurrence, which a wall clock cannot do.

comparator (deprecated)
type: DatatypeProperty
range: string
deprecated: true
definition: Deprecated ADR 0027: use the identified sstim:basisComparator descriptor plus sstim:basisComparatorNote on the qualified basis. Appears only in the generated non-authoritative 0.7 compatibility view.

completion status
type: DatatypeProperty
type: FunctionalProperty
domain: Session Instance

configuration digest
type: DatatypeProperty
type: FunctionalProperty
domain: Session Specification
range: string
definition: Lowercase hexadecimal digest of the exact configuration this specification executed. Naming a configuration establishes which one was intended; the digest establishes that it still says what it said, which is what reproducibility requires.

consent basis note

range: langString
definition: The applicable consent or ethics basis for a governed research output, or an explicit not-applicable determination.

cycle duration
type: DatatypeProperty
type: FunctionalProperty
domain: Voice

definition: Duration of one repeated control or sequence cycle, in seconds.

delivered duration (s)
type: DatatypeProperty
type: FunctionalProperty
domain: Session Instance
range: decimal
definition: Time during which the session was actually delivering stimulus, excluding paused intervals. Distinct from the elapsed duration: a session paused for ten minutes and a session that ran ten minutes shorter have the same elapsed time and different exposures, and only this quantity describes what reached the subject.

type: DatatypeProperty
type: FunctionalProperty
domain: Class
  union of: Preset
  union of: Session Specification
range: integer
definition: Intended total duration in whole seconds, either of a session specification or as the default carried by a preset.
scope note: Whole seconds deliberately, as with sstim:actualDurationSeconds and unlike the decimal durations around it. This is an intended duration — something a person chose, or a preset shipped as its default — and intent is not authored at sub-second precision. What actually happened is measured separately and finely: sstim:deliveredDurationSeconds is a decimal. Recorded because the second-pass review of 2026-08-17 found two integer durations among nine decimals with nothing saying whether the difference was meaningful; the other one was answered the same day and this one was not.

evidence date (deprecated)
type: DatatypeProperty
type: FunctionalProperty
range: date
deprecated: true
definition: Deprecated ADR 0027: source publication dates stay as dct:issued on the bibliographic reference; assessment and review dates come from their generating activities. A non-authoritative 0.7 compatibility view may derive it.

evidence outcome (deprecated)
type: DatatypeProperty
range: string
deprecated: true
definition: Deprecated ADR 0027: use the identified sstim:basisObservedOutcome concept plus sstim:basisOutcomeNote on the qualified basis. Appears only in the generated non-authoritative 0.7 compatibility view.

type: FunctionalProperty
domain: Unwanted Experience Observation

extended maximum frequency (Hz)
type: DatatypeProperty
type: FunctionalProperty
domain: Neural Oscillation Type
range: decimal
definition: Highest frequency at which this rhythm is reported to occur, which may exceed its conventional ambit.

extended minimum frequency (Hz)
type: DatatypeProperty
type: FunctionalProperty
domain: Neural Oscillation Type
range: decimal
definition: Lowest frequency at which this rhythm is reported to occur, which may fall below its conventional ambit. A rhythm modulates and its edges are conventional rather than sharp; recording only the typical ambit would assert a precision the phenomenon does not have.

flash rate (Hz)
type: DatatypeProperty
type: FunctionalProperty
domain: Stimulus Channel
range: decimal
definition: Rate of luminance alternation presented to the subject, in hertz. Safety-bearing: rates in the photosensitive range are constrained at runtime rather than merely recorded.

focus rating
type: DatatypeProperty
type: FunctionalProperty

definition: True iff the preset contains exactly one voice with isOn=true. Governs visual breathing animation and haptic pulse delivery.

has cortical topography
type: DatatypeProperty
domain: Neural Oscillation Type
range: string
definition: Scalp or cortical region over which this rhythm is characteristically recorded. Topography is part of how a rhythm is identified alongside frequency: occipital alpha and central mu occupy overlapping ambits and are told apart by where they appear.

has oscillation state context
type: DatatypeProperty
domain: Neural Oscillation Type
range: string
definition: Behavioural or physiological state in which this rhythm is characteristically observed, such as eyes closed or slow-wave sleep.
editorial note: An observation condition, not an outcome. It records when the rhythm is seen, never what stimulating at that frequency does for anyone: effect and function statements are evidence claims with a tier, a source and a population, and never appear here.

Hz maximum
type: DatatypeProperty
type: FunctionalProperty
domain: Class
  union of: Frequency Band
  union of: Stimulation Signal
range: decimal
definition: Upper bound (inclusive) of a frequency extent in Hz, whether that extent is a named band or the extent a signal occupies.
history note: Domain widened 2026-08-16 (ADR 0052) from sstim:FrequencyBand to a union with sstim:StimulationSignal. The bound means the same thing in both — the upper edge of a frequency extent — and a signal needs one because noise spans a range rather than sitting at a point. Existing band assertions are unaffected.

history note: Domain widened 2026-08-16 (ADR 0052) from sstim:FrequencyBand to a union with sstim:StimulationSignal. The bound means the same thing in both — the lower edge of a frequency extent — and a signal needs one because noise spans a range rather than sitting at a point. Existing band assertions are unaffected.

type: DatatypeProperty
type: FunctionalProperty
domain: Session Event
range: decimal
definition: The value the changed quantity held immediately after this event, in the unit the parameter kind is measured in. On a safety-limit event this is the value actually delivered.
scope note: Unitless here on purpose: the unit follows from the parameter kind and the channel it applies to, and carrying a unit string on every event would invite two records of the same change to disagree about it.

parameter value before
type: DatatypeProperty
type: FunctionalProperty
domain: Session Event
range: decimal
definition: The value the changed quantity held immediately before this event. On a safety-limit event this is the value that was requested, which is the half a consumer cannot reconstruct from the delivered value alone.
scope note: Optional. At the first change of a session the prior value is the one the specification declares, and repeating it here would be derived rather than observed.

permitted use scope
type: DatatypeProperty
range: langString
definition: The permitted use and release scope of a governed research output as evidence.

permutation function
type: DatatypeProperty
type: FunctionalProperty
domain: Voice
range: integer
definition: Permutation function selector for sequence ordering. Values match the skos:notation of sstim-v:PermutationFunctionScheme members (0=shuffle, 1=rotate forward, 2=rotate backward, 3=reverse, 4=identity).

platform deliverable
type: DatatypeProperty
type: FunctionalProperty
domain: Sensory Modality
range: boolean
definition: Whether this modality is deliverable via standard consumer digital platforms without dedicated hardware.

preset version
type: DatatypeProperty
type: FunctionalProperty
domain: Preset
range: string
definition: Semantic version string (X.Y.Z) of this preset.

primary affect
type: DatatypeProperty
type: FunctionalProperty
domain: Self-Report
range: integer
definition: Affect rating at the report's declared collection phase, from 1 (very negative) to 5 (very positive).

prompt identifier
type: DatatypeProperty
type: FunctionalProperty
domain: Participant Observation
range: string
definition: Stable identifier of the question as shown, within its instrument.

prompt text
type: DatatypeProperty
domain: Participant Observation
range: string
definition: The exact wording shown to the participant.
editorial note: Prompts must stay neutral with respect to the session's intended effect: a question that names the hoped-for outcome produces an answer about the question.

proposition digest
type: DatatypeProperty
type: FunctionalProperty
range: string
definition: An immutable content digest identifying the exact proposition when text alone is insufficient.

proposition text
type: DatatypeProperty
range: langString
definition: The exact language-tagged text of an atomic assessment proposition.

pulse rate
type: DatatypeProperty
type: FunctionalProperty
domain: Class
  union of: Audio Track
  union of: Control Track
  union of: Voice
range: decimal
definition: Rhythmic pulse or sequence step rate in Hz.

recommended action
type: DatatypeProperty
domain: Caution Tag

definition: Plain-language action an interface should present when a caution applies, such as reduce intensity, disable a channel, stop, or avoid the context.

reference key
type: DatatypeProperty
type: FunctionalProperty
domain: Public-Safe Reference
range: string
definition: Short uppercase key (e.g. 'INGENDOH_2023') matching citation keys in preset techDesc fields.

rendering carrier (Hz)
type: DatatypeProperty
type: FunctionalProperty
domain: Signal Rendering
range: decimal
definition: The carrier frequency this rendering uses, where it needs one. A carrier exists because of a limitation of the sense being addressed and not because of anything about the signal: 10 Hz is below the audible range and must be carried, while a 10 Hz light flicker or vibration is presented directly and has no carrier at all.
scope note: Beside sstim-ex:hasCarrierFrequencyHz, which states the same quantity one layer down. This one is a fact about a binding — what this rendering uses to carry this signal — and belongs to the specification layer; the exposure one is a fact about emission, what the channel physically puts out, and answers the generic "what frequencies does this channel present?" through its place in the sstim-ex:hasFrequencyHz family. A channel may carry several renderings, so the rendering-level value is the finer of the two. Where both are asserted a SHACL constraint requires them to agree.

reported confidence
type: DatatypeProperty
type: FunctionalProperty
domain: Participant Observation
range: decimal
definition: How confident the participant said they were in their own answer, from 0 to 1, where the instrument collects it.

requires evidence tier rank
type: DatatypeProperty
type: FunctionalProperty
domain: Public Claim Level
range: integer
definition: Minimum sstim:tierRank of supporting evidence required to assert at this claim level on a public surface. 0 = no evidence required (descriptive/experiential/wellness). A value of 7 is an intentional sentinel above the maximum tier (6): no evidence can satisfy it, i.e. the level is never publicly assertable (C4 medical/condition). PROVISIONAL policy mapping — reconcile with the BioSynCare Reference publicClaimLevel/clinicalScope enum and a qualified EU MDR adviser before launch.

reviewed by (deprecated)
type: DatatypeProperty
range: string
deprecated: true
definition: Deprecated ADR 0027: reviewer identity and role live on the review activity's prov:qualifiedAssociation as agent IRIs, not name literals. A non-authoritative 0.7 compatibility view may derive it.

type: DatatypeProperty
type: FunctionalProperty
domain: Class
  union of: Session Specification
  union of: Visual Track

scale minimum label
type: DatatypeProperty

range: string
definition: Anchor text shown at the low end of the scale, without which the number is not interpretable.

scheduled start
type: DatatypeProperty
type: FunctionalProperty
domain: Session Specification
range: dateTime
definition: Intended start time of the session. A property of the plan, not of any execution: sstim:SessionInstance records when a session actually ran.

search coverage end
type: DatatypeProperty
type: FunctionalProperty
range: date
definition: The latest date the search covered; the as-of date of a scoped search finding.

definition: The number of results the executed search returned.

search source
type: DatatypeProperty
range: string
definition: A database or source searched, one value per source.

session clock offset (s)
type: DatatypeProperty
type: FunctionalProperty
domain: Class
  union of: Self-Report
  union of: Session Event
range: decimal
definition: Seconds elapsed on the session's timing context between the clock origin recorded on the session instance and this occurrence. Offsets order the timeline; wall-clock timestamps, where present, place the session in the calendar and order nothing.
scope note: Applies to anything placed on that clock. An event always is. A self-report is only when it was collected during delivery — a pre-session or follow-up report happens off the session clock, and an offset for it would be a fabricated placement.

sleepiness
type: DatatypeProperty
type: FunctionalProperty
domain: Self-Report
range: integer
definition: Sleepiness rating at the report's declared collection phase, from 1 (alert) to 5 (very drowsy).

sound pressure level (dB SPL)
type: DatatypeProperty
type: FunctionalProperty
domain: Stimulus Channel
range: decimal
definition: Sound pressure level at the subject's ear, in decibels SPL. This is the quantity sstim:masterVolume is not: a normalized engine gain is not a level, because the same gain produces different levels on different hardware.

stimulation intensity
type: DatatypeProperty
type: FunctionalProperty
domain: Class
  union of: Haptic Track
  union of: Session Specification
range: decimal
definition: Strength of haptic or sensory output.

stimulus regime
type: DatatypeProperty
type: FunctionalProperty
domain: Stimulus Specification
range: string
definition: Which kind of description this is: "determinate" when the stimulus is fixed in advance, "stochastic" when the specification describes a generating process whose realisations differ, or "adaptive" when the stimulus depends on the subject's measured state and what is described is a control law rather than a stimulus.

study population (deprecated)
type: DatatypeProperty
range: string
deprecated: true
definition: Deprecated ADR 0027: use the identified sstim:basisStudyPopulation descriptor plus sstim:basisPopulationNote on the qualified basis. Appears only in the generated non-authoritative 0.7 compatibility view.

subjective session quality
type: DatatypeProperty
type: FunctionalProperty
domain: Self-Report

type: DatatypeProperty
domain: Ecosystem agent
range: date
is replaced by: created
deprecated: true
definition: The date this ecosystem record was created.

archival consent
type: DatatypeProperty
domain: Ecosystem agent
range: boolean
is replaced by: Consent decision activity
deprecated: true
definition: True only when the agent has given specific, informed consent that the record may enter a permanent, citable archive and cannot then be fully erased (ADR 0024 §6). Absent or false permits only mutable live publication outside the Zenodo-tracked release repository; removal can be honored in the controlled store, but third-party public copies cannot be recalled.

consent status
type: DatatypeProperty
domain: Ecosystem agent
range: string
is replaced by: Consent decision activity
deprecated: true
definition: Listing-tier consent state: implicit-public, notified, consent-requested, consent-granted, consent-declined, removal-requested, or withdrawn (ADR 0024).

contribution status
type: DatatypeProperty
domain: Ecosystem agent
range: string
is replaced by: has ecosystem relationship
deprecated: true
definition: The agent's contribution state relative to SSTIM: none, potential, active, or past.

notification channel
type: DatatypeProperty
domain: Ecosystem agent
range: string
deprecated: true
definition: How the notification was sent (e.g. email, public message, institutional contact).

notification status
type: DatatypeProperty
domain: Ecosystem agent

definition: The date the agent was notified of inclusion in SSTIM.

record source

beat frequency (Hz)
type: DatatypeProperty
sub property of: modulation frequency (Hz)
type: FunctionalProperty
domain: Stimulus Channel
range: decimal
definition: Monaural or binaural beat frequency (the difference frequency) of an audio stimulus channel, in hertz.

carrier frequency (Hz)
type: DatatypeProperty
sub property of: frequency (Hz)
type: FunctionalProperty
domain: Stimulus Channel
range: decimal
definition: The frequency of a carrier this channel presents: a frequency whose job is to bear a signal the sense cannot receive directly. The 200 and 210 Hz tones of a 10 Hz binaural beat are carriers, as is the audible tone an isochronic rate modulates.
scope note: A carrier exists because of a limitation of the sense addressed, not because of anything about the signal: 10 Hz falls below the audible range and must be carried, while a 10 Hz light flicker or vibration is presented directly and has no carrier at all. Beside sstim:renderingCarrierHz, which states the same quantity one layer up, on the rendering that chose it. This one describes emission and joins the sstim-ex:hasFrequencyHz family so a consumer can ask what a channel presents without knowing how it was specified; that one describes a binding. Where both are asserted they must agree, which SHACL enforces.

duty cycle
type: DatatypeProperty
type: FunctionalProperty
domain: Stimulus Channel
range: decimal
definition: On-fraction of each blink or pulse cycle for a stimulus channel, between 0 and 1.

flicker rate (Hz)
type: DatatypeProperty
sub property of: modulation frequency (Hz)
type: FunctionalProperty
domain: Stimulus Channel
range: decimal
definition: Blink, pulse, or flicker rate of a stimulus channel, in hertz. Visual flicker rate is subject to photosensitivity exposure limits.

frequency (Hz)
type: DatatypeProperty
domain: Stimulus Channel
range: decimal
definition: A frequency this stimulus channel presents, in hertz, without saying what role it plays. The generic parent of the frequency family; assert a subproperty where the role is known, and this one only where it genuinely is not.
history note: Until 0.15 this was defined as "carrier or tone frequency" and was functional. Both were wrong for a generic: the two senses are different things, and a channel may present several frequencies at once. ADR 0052 made it the parent of hasCarrierFrequencyHz, hasToneFrequencyHz and hasModulationFrequencyHz, and dropped functionality, which is a weakening — every existing assertion remains valid and now also entails nothing it did not before.

gain level
type: DatatypeProperty
type: FunctionalProperty
domain: Stimulus Channel
range: decimal
definition: Relative output amplitude of a stimulus channel, between 0 and 1. This is a relative level, not a calibrated physical intensity.

modulation frequency (Hz)
type: DatatypeProperty
sub property of: frequency (Hz)
domain: Stimulus Channel
range: decimal
definition: The rate at which something about this channel varies, as distinct from a carrier that bears it. The general case of a flicker rate and of a beat frequency, both of which specialise it.
scope note: Not functional, because a channel may be modulated in more than one respect at once — amplitude at one rate and spatial position at another. Where the modulation is a flicker or a beat, assert the specific subproperty.

phase offset
type: DatatypeProperty
type: FunctionalProperty
domain: Stimulus Channel
range: decimal
definition: Phase offset of a stimulus channel's modulation relative to other channels, as a fraction of a cycle between 0 and 1.

tone frequency (Hz)
type: DatatypeProperty
sub property of: frequency (Hz)
type: FunctionalProperty
domain: Stimulus Channel
range: decimal
definition: The frequency of a tone or periodic stimulus that is itself what reaches the subject, carrying nothing — a 440 Hz reference tone, or a 10 Hz vibration delivered as itself.

knowledge as-of date
type: DatatypeProperty
type: FunctionalProperty
range: date
definition: The date as of which a knowledge-status assertion holds for its named corpus.

knowledge scope note
type: DatatypeProperty
range: langString
definition: A language-tagged description of the corpus or scope of a knowledge-status assertion, used when no scope IRI exists.

limit averaging time
type: DatatypeProperty
type: FunctionalProperty
domain: Exposure Limit
is replaced by: limit averaging time (s)
deprecated: true
definition: Averaging or reference time over which an exposure limit is defined, as an xsd:duration. Deprecated: xsd:duration is outside the OWL 2 datatype map, so its use made the Full closure OWL Full rather than OWL 2 DL. Replaced by sstim-ex:limitAveragingTimeSeconds. The range axiom is withdrawn rather than retyped, so that no xsd:duration reference remains anywhere in the closure.
history note: Deprecated 2026-08-17. Both public values were "PT8H" and are now 28800 seconds on the replacement property.

limit averaging time (s)
type: DatatypeProperty
type: FunctionalProperty
domain: Exposure Limit
range: decimal
definition: Averaging or reference time over which an exposure limit is defined, in seconds — an 8-hour dose is 28800. Seconds rather than a duration literal because xsd:duration is only partially ordered (P1M and P30D are not comparable) and is therefore outside the OWL 2 datatype map, which put every Full closure in OWL Full. Carrying the unit in the property name follows the SSTIM parameter convention.

limit maximum frequency (Hz)
type: DatatypeProperty
type: FunctionalProperty
domain: Exposure Limit
range: decimal
definition: Maximum frequency permitted by a cited exposure or accessibility rule, in hertz; compliance with the value is not an individual safety guarantee.

limit quantity
type: DatatypeProperty
type: FunctionalProperty
domain: Exposure Limit
range: string
definition: Physical quantity an exposure limit constrains (for example "flash frequency", "sound pressure level", or "effective irradiance").

limit unit
type: DatatypeProperty
type: FunctionalProperty
domain: Exposure Limit
range: string
definition: Unit of an exposure limit value (for example "dBA" or "J/m2"). A QUDT unit IRI may be linked separately where precision is required.

limit value
type: DatatypeProperty
type: FunctionalProperty
domain: Exposure Limit
range: decimal
definition: Numeric value of an exposure limit, interpreted together with limitUnit and limitQuantity.

pitch shift (cents)
type: DatatypeProperty
type: FunctionalProperty
domain: Stimulus Channel
range: decimal
definition: Resulting pitch shift in cents relative to the standard reference (e.g. about -31.77 cents for A4=432 versus A4=440).

reference pitch (Hz)
type: DatatypeProperty
type: FunctionalProperty
domain: Stimulus Channel
range: decimal
definition: Frequency in hertz assigned to the reference note (e.g. 432 or 440 for A4). This is a carrier/absolute-pitch attribute, not a modulation or beat frequency.

reference pitch note
type: DatatypeProperty
type: FunctionalProperty
domain: Stimulus Channel
range: string
definition: Named reference note whose pitch a tuning sets, commonly "A4".

retuned from reference (Hz)
type: DatatypeProperty
type: FunctionalProperty
domain: Stimulus Channel
range: decimal
definition: Standard reference frequency the tuning departs from, typically 440 Hz for A4.

Assessment Proposition
type: Class
subclass of: information content entity
definition: One immutable, atomic, independently assessable proposition evaluated by an evidence assessment: exactly one subject, one outcome concept, one scope, one proposition form, and exact text or digest.

Assessment Scope
type: Class
subclass of: information content entity
definition: The explicit modality, population/model, intervention/context, and comparator scope of an assessment proposition. Every axis carries a named value or an explicit unknown / not-reported / not-applicable marker; omission never means universal applicability.

Audio Track
type: Class
subclass of: Track
definition: A track whose output is audible: an isochronic tone, a binaural carrier pair, a plain carrier, noise, a drone, or a sample.

Bibliographic Reference
type: Class
subclass of: information content entity
definition: A bibliographic record of a published source. Being recorded implies neither endorsement nor permission to quote, reproduce, or display the source.

Binaural Voice
type: Class
subclass of: Voice
definition: Two sine tones at slightly different frequencies (fl, fr) presented dichotically to produce a perceived beat at |fr - fl| Hz.

Canonical Sensory Transduction Access Route
type: Class
subclass of: Neural Access Route
definition: A neural access route that engages canonical sensory receptor transduction and afferent processing. This is the route value that distinguishes the sensory-route neuromodulation overlap from approaches that bypass canonical sensory transduction.

Caution Severity
type: Class
subclass of: information content entity
definition: A controlled ordinal category for prioritizing a caution tag in user interfaces and validation. Severity describes the response required by the application; it is not a clinical diagnosis or risk probability.

Caution Tag
type: Class
subclass of: information content entity
label: Etichetta di Cautela @it
label: Etiqueta de Cautela @pt
label: Etiqueta de Precaución @es
definition: A safety or usage advisory flag attached to a preset, signalling conditions under which the preset may be unsuitable (e.g. photosensitivity risk, drowsiness, high sensory intensity). Advisory wellness metadata, not a medical contraindication.

Claim Direction
type: Class
subclass of: information content entity
definition: Whether a body of evidence supports, is mixed on, is inconclusive about, or refutes the asserted relation.

Comparator Descriptor
type: Class
subclass of: information content entity
definition: An identified description of the comparison condition (for example sham, no-stimulus, baseline, or alternative frequency) referenced by an assessment scope or evidence basis.

Conflict Disclosure
type: Class
subclass of: information content entity
definition: A record of declared conflicts of interest for a review, including the explicit declaration that no conflict was declared.

Control Track
type: Class
subclass of: Track
definition: A track that produces no sensory output of its own and instead supplies a time-varying control signal modulating parameters of other tracks. Breathing-guidance (Martigli) and symmetry-derived control signals are the current kinds.
editorial note: The modulation this definition describes is prose the graph cannot state: no property links a control track to the track and parameter it modulates. Two consequences follow. A configuration cannot be read to discover what drives what, and the control signal is not separable from the preset that contains it, so no shared signal object exists for two channels or two studies to be compared by. This is the abstract-signal half of SSTIM_DIRECTIONS.md §5: a time-varying function with a period or envelope and no modality, which a rendering then binds to a renderable parameter of some sensory channel. Carrier and modulator describe one audio rendering of such a signal, not the general structure — a carrier is needed because 10 Hz falls below the audible range, while a 10 Hz light flicker or vibration is presented directly.

Deliberate Self-Regulation
type: Class
subclass of: process
label: Autoregolazione Deliberata @it
label: Autorregulación Deliberada @es
label: Autorregulação Deliberada @pt
definition: A deliberate process in which an individual attempts to regulate their own neural, physiological, or affective state, whether or not an external stimulus, cue, or delivery mechanism is part of the process. The neutral genus for self-directed practices: unlike sstim:Stimulation, it carries no commitment to an applied controlled input.
scope note: Practices that also involve an applied stimulus, cue, or feedback delivery — neurofeedback, biofeedback, paced-breathing guidance — are additionally sstim:SelfDirectedNeuromodulation, since they meet sstim:Stimulation's applied-input requirement through sstim:Neuromodulation. Pure practices with no applied stimulus — unguided meditation, volitional breathwork — are sstim:DeliberateSelfRegulation only: SSTIM does not represent them as a stimulation, a neuromodulation, or a stimulation technique, however deliberate or goal-directed (ADR 0037).

Effect Direction
type: Class
subclass of: information content entity
definition: The direction of the measured outcome (increase, decrease, or no change). Wellness-neutral; describes what was measured, not a health claim.

Entrainment-Based Technique
type: Class
subclass of: Sensory Stimulation Technique
disjoint with: Non-Entrainment Technique
definition: A Sensory Stimulation technique whose primary proposed mechanism involves frequency-following responses, phase-locking, or oscillatory coupling between a periodic stimulus and endogenous neural oscillations.
example: Binaural beat stimulation, isochronous tone stimulation, photic driving, Symmetry permutation entrainment.

Evidence Assessment Activity
type: Class
subclass of: Activity
definition: The PROV activity that generates an evidence assessment revision. It used every qualified basis, its sources, and the immutable rubric/method revision actually applied, and carries a qualified association naming the responsible agent and role.

Evidence Assessment Claim
type: Class
subclass of: Evidence Claim
definition: A versioned, immutable assessment of an identified evidence basis about one atomic bounded proposition. The sole concrete evidence-bearing class: exactly one evidence tier and one claim direction, at least one qualified evidence basis, and exactly one assessed proposition. A correction mints a new revision IRI linked with prov:wasRevisionOf; it never edits a published revision in place.

Evidence Basis
type: Class
subclass of: information content entity
definition: One qualified contribution of a single source to an evidence assessment, carrying source-level modality, intervention, study design, model/population, synthesis, and observed-result metadata separately from the assessment's own conclusion.

Evidence Claim
type: Class
subclass of: information content entity
definition: Compatibility superclass of evidence assessments. Direct instantiation is rejected by SHACL: every instance must carry a concrete evidence subtype (sstim:EvidenceAssessmentClaim). Hypotheses, research questions, boundary applicability, requirements, design objectives, planned outcomes, knowledge-status assertions, and session observations are never EvidenceClaims.
history note: Narrowed 2026-07-13 (ADR 0027) from a single overloaded claim class to the compatibility superclass of EvidenceAssessmentClaim.

Evidence Modality Tag (deprecated)
type: Class
subclass of: information content entity
deprecated: true
definition: Deprecated ADR 0027: the tag conflated sensory modality (AUD, AV, VIS, TACTILE, MULTISENSORY), intervention (BREATH), study model (PRECLINICAL), and synthesis type (REVIEW). Authoritative data uses the orthogonal basis axes; the class survives only for the generated non-authoritative 0.7 compatibility view and is removed no earlier than 1.0.

Evidence Outcome Concept
type: Class
subclass of: information content entity
definition: A controlled endpoint, response, or mechanism category used to identify what a proposition or reported source result is about. It is a category, not an observed result or benefit.

Evidence Proposition Form
type: Class
subclass of: information content entity
definition: The logical form of an assessment proposition: bounded relation, bounded null result, scoped search finding, or universal absence. Universal-absence propositions never conform; a scoped search finding requires an evidence search record basis.

Evidence Review Activity
type: Class
subclass of: Activity
definition: The PROV activity that reviews exactly one assessment revision under a named rubric/policy revision and generates an immutable evidence review decision.

Evidence Review Decision
type: Class
subclass of: information content entity
definition: An immutable review decision about one assessment revision: reviewer relationship, independence determination, and decision are independent axes. A later decision supersedes or invalidates the earlier one; no mutable effective-review pointer exists.

Evidence Search Activity
type: Class
subclass of: Activity
definition: The PROV activity that executes an evidence search and generates an immutable evidence search record, with execution times and a qualified responsible agent/role.

Evidence Search Record
type: Class
subclass of: information content entity
definition: An immutable, reproducible record of a literature/evidence search: sources, exact query, coverage dates, eligibility criteria, result count, and content digest. Supports only scoped 'no eligible evidence found' findings, never universal absence.

Evidence Synthesis Type
type: Class
subclass of: information content entity
definition: The synthesis level of an evidence source: primary study, narrative review, systematic review, meta-analysis, literature review, or tutorial. A narrative review does not acquire systematic-review status merely because it synthesizes literature.

Evidence Tier Value
type: Class
subclass of: information content entity
definition: A classification of empirical support strength for a specific stimulation claim, accounting for study quality, result consistency, modality match, and population match. Six tiers: speculative(1) through established(6). A tier is meaningful only together with the claim direction and the bounded proposition scope it was assigned to.

Experience Onset Phase
type: Class
subclass of: information content entity
definition: A controlled category locating when an unwanted experience began, relative to the session.

Experience Persistence
type: Class
subclass of: information content entity
definition: A controlled category recording how long an unwanted experience lasted, as the participant described it.

Experience Resolution
type: Class
subclass of: information content entity
definition: A controlled category recording the state an unwanted experience reached.

Experience Response Action
type: Class
subclass of: information content entity
definition: A controlled category recording what the participant did in response to an unwanted experience.

Frequency Band
type: Class
subclass of: information content entity
label: Banda de Frecuencia @es
label: Banda de Frequência @pt
label: Banda di Frequenza @it
definition: An information entity describing a named Hz range used in BSC protocol design for targeting and evidence classification. BSC operational design category — not a medical diagnostic taxonomy or universal EEG ontology.

Frequency Band Group
type: Class
subclass of: information content entity
label: Grupo de Bandas de Frecuencia @es
label: Grupo de Bandas de Frequência @pt
label: Gruppo di Bande di Frequenza @it
definition: A named collection of frequency bands used as a SKOS scheme root or aggregate grouping concept. Not a band with a specific Hz range; used for SKOS hierarchy navigation (skos:narrower* traversal) rather than for range arithmetic.

Governed Research Output
type: Class
subclass of: Entity
definition: A versioned study record, dataset revision, or analysis output admitted as an evidence source. Requires exactly one source-governance record; an ungoverned dataset cannot serve as an evidence basis source.

Haptic Track
type: Class
subclass of: Track
definition: A track whose output is delivered as vibration through a device actuator.

Independence Determination
type: Class
subclass of: information content entity
definition: A policy-based determination of reviewer independence: independent, not independent, or undetermined. An independent or not-independent determination requires a named independence policy and conflict disclosure.

Intended Effect
type: Class
subclass of: information content entity
definition: A controlled information category identifying a target change in physiological, psychological, or cognitive state that a sensory stimulation intervention is designed to facilitate. It records design intent, not a guaranteed outcome.

Interventional Neuromodulation
type: Class
subclass of: Neuromodulation
label: Neuromodulación Intervencionista @es
label: Neuromodulazione Interventistica @it
label: Neuromodulação Intervencionista @pt
definition: Neuromodulation applied to an individual by an external agent, device, or agent-administered means. This is the sense the ADR 0034 non-sensory contrast set occupies, and it corresponds on techniques to a non-self participant-engagement mode (passive-receptive or guided-following).

Martigli-Binaural Voice
type: Class
subclass of: Voice
definition: Binaural beat combined with Martigli breathing oscillation. Both carriers sweep in parallel, maintaining constant beat frequency while timbral register evolves with breathing.

Martigli Voice
type: Class
subclass of: Voice
definition: A single tone whose frequency oscillates sinusoidally with a breathing arc that decelerates linearly from mp0 to mp1 over md seconds.

Modality Applicability
type: Class
subclass of: information content entity
definition: A controlled statement of how sensory modality applies to an evidence source: mixed modalities, unknown/not reported, or not applicable. Distinct states, never a wildcard.

Neural Access Route
type: Class
subclass of: information content entity
definition: A controlled category for the biological route through which a stimulation process is intended to engage a neural target. Route values describe the declared intended route; a competing or demonstrated actual mechanism remains an evidence-qualified statement recorded on a mechanism or outcome concept.
scope note: 'Receptor' on this axis means a canonical sensory receptor, never a molecular drug receptor. Mixed access is represented by multiple route values, which is not the same as uncertainty; an unresolved route is an epistemic status recorded by a scoped knowledge-status assertion, not a pseudo-route.

Neural Oscillation Type
type: Class
subclass of: information content entity
label: Tipo de Oscilación Neural @es
label: Tipo de Oscilação Neural @pt
label: Tipo di Oscillazione Neurale @it
definition: A controlled information category for a named rhythmic fluctuation of neural activity, such as the alpha or theta rhythm. Members are identified by a conventional frequency ambit together with characteristic recording topography and observation state; the ambit alone does not identify one.
scope note: A category, not the rhythm. Following ADR 0021, this classifies a real neurophysiological phenomenon without being that phenomenon: SSTIM records no measured neural activity, so there is no class of measured oscillation events and no instance of one. Distinct from sstim:FrequencyBand, which is a Hz interval and nothing more, and from sstim:NeuralPhenomenon, which categorises kinds of phenomena such as oscillatory dynamics rather than the named rhythms themselves.

Neural Phenomenon
type: Class
subclass of: information content entity
definition: A controlled information category for a coherent functional neural phenomenon, such as excitability or firing, oscillatory dynamics, temporal coordination, synaptic transmission, neurochemical signaling, connectivity or plasticity, and autonomic neural regulation.
scope note: One value set is reused across proposed-mechanism, intended-target, and observed-outcome roles, which are kept distinct by three separate properties. This axis replaces any single 'target level' axis: a route, a dynamic, a system, and an outcome domain are not values on one scale.

Neural System
type: Class
subclass of: information content entity
definition: A controlled information category for a distributed organizational neural system — sensory, motor, autonomic, or a named sensory subsystem. This is the axis for neuromodulation of a sensory system; it does not imply that the intervention entered through that sensory system.

Neural Target Site
type: Class
subclass of: information content entity
definition: A controlled information category for a broad anatomical target of a stimulation process, such as brain, cortex, deep-brain structure, spinal cord, peripheral nerve, or cranial nerve. It is a classification category, not the anatomical entity itself.
scope note: A local target category may have more than one broader concept; no forced single-parent tree is required. External anatomy alignment is a separate, evidence-checked pass.

Neuromodulation
type: Class
subclass of: Stimulation
label: Neuromodulación @es
label: Neuromodulazione @it
label: Neuromodulação @pt
definition: In SSTIM, a deliberately applied stimulation process whose declared intervention objective is to alter activity or function at an identified neural target. Anatomical site and distributed neural system are recorded on separate facets. Membership records target and design intent; whether modulation occurred is represented separately through observations and evidence.
note: Two different definitions live in the word 'neuromodulation'; SSTIM keeps them apart. (1) By SENSE: this class is neuromodulation as INTERVENTION — an applied process intending to modulate. The neurophysiological EFFECT sense — the resulting change in neural activity — is not this class but a neural phenomenon in the outcome role (sstim:outcomeNeuralPhenomenon); the state-change effects are grouped by sstim-v:NeuromodulatoryEffectCollection. (2) By PARTICIPANT ENGAGEMENT: neuromodulation WITHOUT active engagement of the individual is interventional (sstim:InterventionalNeuromodulation — e.g. neurostimulation); neuromodulation WITH the individual's deliberate self-regulation is self-directed (sstim:SelfDirectedNeuromodulation — e.g. neurofeedback, biofeedback; unguided meditation has no applied stimulus and is sstim:DeliberateSelfRegulation only, ADR 0037). This engagement axis is the one Theo Marins raised on 2026-07-22 (ADR 0035/0036).
scope note: This is the INTERVENTION sense of neuromodulation — a deliberately applied process with the intent to modulate — as distinct from the physiological EFFECT sense (the resulting neural change), which is recorded on the outcome facet (sstim:outcomeNeuralPhenomenon), not here (ADR 0036). It excludes SPONTANEOUS physiological, neurotransmitter-level endogenous neuromodulation and stimulation performed solely to probe or measure a response; but DELIBERATE self-directed neuromodulation IS in scope (sstim:SelfDirectedNeuromodulation, ADR 0036). It does not mean treatment or successful modulation. It neither subsumes nor is subsumed by sstim:SensoryStimulation; the two overlap, and the overlap is named by sstim:SensoryRouteNeuromodulation (ADR 0034).

Neuromodulation Intervention
type: Class
subclass of: Neuromodulation
subclass of: Stimulation Intervention
definition: A specific, designed execution of a neuromodulation process, with a declared neural access route, delivery approach, and intended neural target. Membership does not assert successful modulation, benefit, or safety.

Neuromodulation Protocol
type: Class
subclass of: Stimulation Protocol
definition: A protocol whose planned objective is to alter activity or function at an identified neural target. It remains an information artifact: a protocol records the planned objective through this type plus its route and target facets, while the realized process is typed as an intervention.

Neuromodulation Technique
type: Class
subclass of: Stimulation Technique
label: Tecnica di Neuromodulazione @it
label: Técnica de Neuromodulación @es
label: Técnica de Neuromodulação @pt
definition: A stimulation technique whose defining intervention objective is to alter activity or function at an identified neural target, with anatomical site and distributed neural system recorded separately. Membership does not assert successful modulation, benefit, or safety.
scope note: Cataloguing a neuromodulation technique states that SSTIM can describe it, not that BSC Lab delivers it or that it is effective. A proposed neural mechanism or an evoked response is not by itself a neuromodulation objective (ADR 0034 §2).

Neuroplasticity
type: Class
subclass of: disposition
label: Neuroplasticidad @es
label: Neuroplasticidade @pt
label: Neuroplasticità @it
definition: The disposition of a nervous system to undergo lasting structural or functional change in response to activity, experience, or stimulation. It is the capacity that durable neuromodulation realizes; it is not a process or an intervention.
scope note: Related to neuromodulation bidirectionally, not as a one-way precondition: plasticity enables durable neuromodulatory change, while neuromodulators (e.g. acetylcholine, dopamine, noradrenaline) in turn gate plasticity by setting its induction thresholds. Modelled as a stub in 0.10.0 (ADR 0036); properties relating it to durable effects are deferred.

Neurostimulation
type: Class
subclass of: Interventional Neuromodulation
label: Neuroestimulación @es
label: Neuroestimulação @pt
label: Neurostimolazione @it
definition: Interventional neuromodulation delivered by applied stimulation — energy applied to neural tissue (electrical, magnetic/electromagnetic, acoustic/ultrasonic) or, as its sensory branch, canonical sensory stimulation with a neural-modulation objective. It is the DELIVERY, distinct from the neuromodulatory EFFECT it is intended to cause (recorded on sstim:outcomeNeuralPhenomenon; ADR 0036).
note: How this term is defined, on two axes. (1) DELIVERY vs. EFFECT: neurostimulation is the delivery — the applied stimulation itself — not the neuromodulatory effect it aims to produce. The effect (the resulting change in neural activity) is a separate thing, recorded as a neural phenomenon in the outcome role (sstim:outcomeNeuralPhenomenon), never as this class. (2) PARTICIPANT ENGAGEMENT: neurostimulation is the branch of neuromodulation applied WITHOUT active engagement of the individual — they receive it — as opposed to self-directed neuromodulation (neurofeedback, biofeedback) which the individual actively self-regulates. Theo Marins (2026-07-22) framed neurostimulation precisely as the neuromodulation that does not require the individual's active engagement (see the participant-engagement facet, ADR 0035, and ADR 0036).
scope note: Recovers 'neurostimulation is a type of neuromodulation' as a true statement under the intervention sense (ADR 0036). Kinds such as electric, magnetic, and sensory neurostimulation are views over the delivery-medium and route facets, not primitive subclasses: the sensory kind is sstim:SensoryRouteNeuromodulation. Stimulation applied solely to probe or measure is not neurostimulation in this sense (it lacks the modulation objective), and pharmacological neuromodulation is not neurostimulation at all.

Neurostimulation Technique
type: Class
subclass of: Neuromodulation Technique
label: Tecnica di Neurostimolazione @it
label: Técnica de Neuroestimulación @es
label: Técnica de Neuroestimulação @pt
definition: A neuromodulation technique that delivers applied stimulation — energy applied to neural tissue — rather than a pharmacological agent or the individual's own self-regulation. The technique-layer counterpart of sstim:Neurostimulation, and the browsable parent of the electrical, magnetic, and acoustic/ultrasonic neurostimulation entries.
scope note: Its members share an energy-delivery route (physical neural interaction). The electric/magnetic/acoustic kinds are delivery-medium facet views, not subclasses; the sensory kind is sstim:SensoryNeurostimulationTechnique. Pharmacological neuromodulation (e.g. intrathecal agent delivery) and self-directed neuromodulation (e.g. neurofeedback) are neuromodulation techniques but not neurostimulation, and are deliberately excluded.

Non-Entrainment Technique
type: Class
subclass of: Sensory Stimulation Technique
definition: A Sensory Stimulation technique whose proposed mechanism does not rely on frequency-following responses. Includes stochastic resonance, autonomic respiratory entrainment, and attentional anchoring via ambient structured sound.
example: Calibrated pink noise for stochastic resonance, Martigli breathing oscillation, ambient Symmetry sequences for attentional anchoring.

Observation Instrument
type: Class
subclass of: information content entity
definition: The identified, versioned questionnaire in a given language that produced a set of observations. Reports are not comparable across instrument versions, so an observation without instrument provenance is not analysable.

Observation Role
type: Class
subclass of: information content entity
definition: A controlled category of what a participant observation observes.

Participant Engagement Mode
type: Class
subclass of: information content entity
definition: A controlled information category for the degree and kind of active participation a stimulation or neuromodulation method requires of the individual — from passive reception, through following an external pacing cue, to active self-regulation of one's own state. It records what the method demands of the participant, never whether that participation is effective.
scope note: Orthogonal to the ADR 0034 route, approach, target-site, system, and phenomenon axes: a method's engagement mode is neither implied by nor implies any of them. It is the axis that distinguishes self-regulatory practices (meditation, volitional breathwork, neurofeedback, biofeedback) and cue-following practices (paced-breathing guidance) from purely receptive exposure (binaural beats to a resting listener, tDCS). By itself it never reclassifies a method as neuromodulation; the relationship between active self-regulation and the sstim:Neuromodulation definition is discussed in ADR 0035.

Participant Observation
type: Class
subclass of: information content entity
definition: One qualified answer within a self-report: what was observed, what response state applies, the value if one was supplied, and the prompt and scale that produced it. Addressable in its own right, so an answer can be cited, corrected, or excluded without touching the rest of the report.
scope note: A participant's account of their own experience. It is never an outcome measurement, an efficacy indicator, or evidence, whatever its value.

Perceived Relatedness
type: Class
subclass of: information content entity
definition: A controlled category recording whether the participant perceived an experience as connected to the session. It records a perception and is never promoted to an attribution.

Permutation Function
type: Class
subclass of: information content entity
definition: A named reordering rule applied to a Symmetry voice note sequence at each cycle boundary (identity, rotate forward, rotate backward, reversal, shuffle).

Population Descriptor
type: Class
subclass of: information content entity
definition: An identified description of a study population or participant group referenced by an assessment scope or evidence basis.

Preset
type: Class
subclass of: information content entity
alternative label: Patch
definition: A reusable, versioned parameter configuration that makes a particular engine, instrument or design produce an intended sensory stimulation. A preset follows a protocol or framework but is not itself the protocol, and it is not the stimulation: it is the set of settings from which one engine reproduces it.
history note: Until 0.11.x the definition named "audio architecture" as a constituent. That described the BSC catalog format, not presets: a sensory stimulation preset may carry visual, haptic, respiratory, olfactory, gustatory or electromagnetic layers, as sstim-ex:StimulusChannel already recognises. Corrected by ADR 0041.
scope note: Engine-dependent by nature. Two engines that produce identical stimulation may have entirely unrelated presets, and two research groups will have unrelated schemas, so the field list is a property of a schema rather than of this class. The BSC catalog format and Patch Studio's patch-studio-model-1 are two such schemas; they are conformance profiles of this class, not distinct classes. "Patch" is a synonym, from modular-synthesis usage. The engine-independent description of what actually reaches the subject is sstim:StimulusSpecification, which is a different layer (ADR 0041).

Preset Group
type: Class
subclass of: information content entity
definition: A classification of BSC presets by design character, evidence strength, and use context. Five groups: Heal, Support, Perform, Indulge, Transcend.

Public Claim Level
type: Class
subclass of: information content entity
label: Livello di Affermazione Pubblica @it
label: Nivel de Afirmación Pública @es
label: Nível de Alegação Pública @pt
definition: A named ceiling on what a sensory-stimulation product may assert about itself on a public-facing surface, ordered from descriptive fact to quantified/superiority claims. Each level carries the minimum evidence-tier rank required to assert at that level publicly, so over-claiming is machine-checkable. A risk-reduction classification, not legal advice.

Public-Safe Reference
type: Class
subclass of: information content entity
subclass of: Bibliographic Reference
definition: A peer-reviewed publication cleared for citation in BSC user-facing content. Must be cleared in the BSC Reference Agent before use in preset techDesc fields.

Renderable Parameter
type: Class
subclass of: information content entity
definition: A controlled information category naming the parameter a signal is rendered onto — amplitude, frequency, luminance, size, spatial position, vibration intensity. Which parameters exist is modality-specific; that a signal drives one of them is not.
scope note: This is also the modulation relation. A control signal driving another layer's parameter, such as a breathing oscillation driving spatial position, is a rendering onto that parameter rather than a separate mechanism.

Rendering Mechanism
type: Class
subclass of: information content entity
definition: A controlled information category naming how a signal is made to reach a subject through one channel: amplitude modulation of a carrier, a binaural or monaural beat, direct presentation, and so on. The mechanism is a property of the rendering, not of the signal.

Rendering Presence
type: Class
subclass of: information content entity
definition: A controlled information category recording whether a rendering puts the signal physically into the world or produces it perceptually. An isochronic tone and a visual flicker are physically present; a binaural beat is not, being constructed by the auditory system from two carriers that each lack it.
scope note: Load-bearing for evidence, not descriptive: a finding about a physically present 10 Hz modulation does not transfer freely to a perceptually constructed one, even within the same modality.

Reported Severity
type: Class
subclass of: information content entity
definition: A controlled category recording how severe a participant said an experience was.

Reproducibility Level
type: Class
subclass of: information content entity
definition: A controlled category stating which reproduction claim a session record supports: identical rendered output, equivalent generated signal within numerical tolerance, or only the same targets, arc, architecture and duration.

Response State
type: Class
subclass of: information content entity
definition: A controlled category stating why a value is or is not present on an observation.

Review Decision Value
type: Class
subclass of: information content entity
definition: The outcome of an evidence review: confirm, request revision, or reject.

Review Status
type: Class
subclass of: information content entity
definition: The audit status of an evidence claim's tier assignment (provisional, reviewed, or needs update).

Reviewer Relationship
type: Class
subclass of: information content entity
definition: The relationship of a review's agent to the assessed work: self, same organization, external, or unknown. External relationship never implies independence.

Scope Marker
type: Class
subclass of: information content entity
definition: A controlled marker stating that a scope axis is unknown, not reported, or not applicable. Mutually exclusive with concrete values on the same axis.

Self-Directed Neuromodulation
type: Class
subclass of: Deliberate Self-Regulation
subclass of: Neuromodulation
label: Neuromodulación Autodirigida @es
label: Neuromodulazione Autodiretta @it
label: Neuromodulação Autodirigida @pt
definition: Neuromodulation produced by the individual's own deliberate self-regulation via an applied stimulus, cue, or feedback delivery — for example neurofeedback, biofeedback, or paced-breathing guidance — corresponding on techniques to the active-self-regulatory participant-engagement mode (ADR 0035). Requires a delivery medium, like every sstim:Stimulation; a practice with no applied stimulus is sstim:DeliberateSelfRegulation but not this class (ADR 0037).
scope note: Distinct from the spontaneous physiological, neurotransmitter-level endogenous neuromodulation that sstim:Neuromodulation excludes: self-directed neuromodulation is deliberate and stimulus-mediated. sstim:DeliberateSelfRegulation is the neutral genus that also covers practices with no applied stimulus (unguided meditation, volitional breathwork), which are not this class (ADR 0037).

Self-Report
type: Class
subclass of: information content entity
definition: A consent-governed, session-associated collection event gathering a participant's own account at an explicitly identified phase. Its content is a set of qualified participant observations, each carrying the prompt, scale and response state that make it interpretable.
history note: Definition revised 2026-08-13 (ADR 0048). The previous wording promised optional free text that no property supported, and named five fixed values as the report's content.
scope note: The five scalar properties below — primary affect, focus rating, sleepiness, subjective quality and goal achieved — remain valid as documented simple projections of that model, and existing data keeps its meaning. They carry the answer and drop everything that qualifies it, so new authoring should attach sstim:ParticipantObservation instances and treat the scalars as a summary.

Self-Report Phase
type: Class
subclass of: information content entity
definition: A controlled category identifying when a self-report was collected relative to its associated session, such as before, immediately after, or at follow-up.

Sensory Modality
type: Class
subclass of: information content entity
label: Modalidad Sensorial @es
label: Modalidade Sensorial @pt
label: Modalità Sensoriale @it
definition: A controlled information category identifying a channel of sensory perception through which stimulation is delivered or perceived. Values include auditory, visual, somatosensory, interoceptive, vestibular, and olfactory.

Sensory Neurostimulation
type: Class
equivalent class: Class
  intersection of: Neurostimulation
  intersection of: Sensory-Route Neuromodulation
subclass of: Neurostimulation
subclass of: Sensory-Route Neuromodulation
definition: The sensory kind of neurostimulation: canonical sensory stimulation delivered without the individual's active self-regulation, with a neural-modulation objective. The intersection of sstim:Neurostimulation and sstim:SensoryRouteNeuromodulation, not a further primitive class.
scope note: A sensory-route neuromodulation case that is instead self-directed (for example sonification-based biofeedback) is sstim:SensoryRouteNeuromodulation but not this class, because it does not meet sstim:Neurostimulation's own exclusion of self-directed cases (ADR 0036).

Sensory Neurostimulation Technique
type: Class
equivalent class: Class
  intersection of: Neurostimulation Technique
  intersection of: Sensory-Route Neuromodulation Technique
subclass of: Neurostimulation Technique
subclass of: Sensory-Route Neuromodulation Technique
definition: The technique-layer counterpart of sstim:SensoryNeurostimulation: a sensory-route neuromodulation technique delivered without the individual's active self-regulation. The intersection of sstim:NeurostimulationTechnique and sstim:SensoryRouteNeuromodulationTechnique, not a further primitive class.

subclass of: Neuromodulation
subclass of: Sensory Stimulation
label: Neuromodulación por Vía Sensorial @es
label: Neuromodulazione per Via Sensoriale @it
label: Neuromodulação por Via Sensorial @pt
definition: A stimulation process that is both sensory stimulation and neuromodulation, and that declares canonical sensory transduction and afferent processing as an intended causal route. This is the overlap of the two families, not a subclass of either alone.
scope note: Distinct from neuromodulation of a sensory system, which is a target-axis statement, and from a sensation merely accompanying neuromodulation, which is recorded through perceived modality and channel role (ADR 0034 §2).

Sensory-Route Neuromodulation Intervention
type: Class
equivalent class: Class

  intersection of: Sensory Stimulation Intervention
  intersection of: Restriction

Sensory-Route Neuromodulation Technique

  intersection of: Neuromodulation Technique
  intersection of: Sensory Stimulation Technique
  intersection of: Restriction
    on property: neural access route
    some values from: Canonical Sensory Transduction Access Route
subclass of: Neuromodulation Technique
subclass of: Sensory Stimulation Technique
definition: A technique that is both a sensory stimulation technique and a neuromodulation technique, declaring canonical sensory transduction and afferent processing as an intended causal route. A technique is dual-typed here only when neural-modulation intent is part of the technique concept's own definition, never because one possible use is neuromodulatory.

Sensory Stimulation
type: Class
subclass of: process
subclass of: Stimulation
label: Estimulación Sensorial @es
label: Estimulação Sensorial @pt
label: Stimolazione Sensoriale @it
definition: A stimulation process whose defining intervention route engages canonical sensory transduction and afferent processing with structured input delivered according to specified parameters for a declared purpose. The class identifies the delivery process; any mechanism, response, or outcome is represented separately and requires its own evidence.
narrow match: http://snomed.info/id/226056003
scope note: Conscious perception is not required, and an incidental sensation arising from another primary route is insufficient. Covers entrainment-based stimulation (binaural beats, isochronous tones), non-entrainment stimulation (stochastic resonance, attentional anchoring), and autonomic stimulation (paced respiratory entrainment). Does not include passive incidental sensory exposure.

editorial note: Intension: the SNOMED concept carries an explicit therapeutic intent attribute, while this class admits experimental, expressive, accessibility and informational purposes and asserts no therapeutic commitment. Extension: the SNOMED concept subsumes clinical tactile technique, while this class covers binaural beats, photic driving and isochronic tones, which it does not subsume. Hence narrowMatch. Deliberately not closeMatch: asserting interchangeability would import a therapeutic framing this project disclaims (docs/concept/SCOPE.md and the no-medical-claims invariant).

Sensory Stimulation Framework
type: Class
subclass of: information content entity
definition: A broad information artifact defining a family of sensory stimulation principles, techniques, protocols, evidence rules, grouping logic, and design constraints. A framework can guide multiple protocols, implementations, presets, and sessions.

Sensory Stimulation Implementation
type: Class
subclass of: Entity
disjoint with: Ecosystem agent
definition: A concrete realization of a sensory stimulation framework or protocol, represented in SSTIM by the implementation identity and metadata. An implementation can be software, hardware, mechanical, manual, or hybrid.

Sensory Stimulation Intervention
type: Class
subclass of: planned process
subclass of: Sensory Stimulation
subclass of: Stimulation Intervention
label: Intervención de Estimulación Sensorial @es
label: Intervento di Stimolazione Sensoriale @it
label: Intervenção de Estimulação Sensorial @pt
definition: A specific, designed execution of Sensory Stimulation with defined parameters, target modalities, intended effect, and delivery mechanism. An intervention can realize a session specification derived from a preset, protocol, or framework.

Sensory Stimulation Protocol
type: Class
subclass of: information content entity
subclass of: protocol
subclass of: Stimulation Protocol
definition: A structured method specification for using one or more sensory stimulation techniques toward an intended use, including composition rules, timing, parameter ranges, constraints, and cautions. A protocol is narrower than a framework and can constrain many presets.

Sensory Stimulation Technique
type: Class
subclass of: information content entity
subclass of: Stimulation Technique
label: Tecnica di Stimolazione Sensoriale @it
label: Técnica de Estimulación Sensorial @es
label: Técnica de Estimulação Sensorial @pt
definition: An information-content category for a reusable, parameterizable method of sensory stimulation, characterized by stimulus form, delivery mechanism, and any explicitly proposed response mechanism. A technique is less specific than a protocol and does not by itself provide enough detail to reproduce an intervention.

Sensory-Transduction-Bypassing Access Route
type: Class
subclass of: Neural Access Route
definition: A neural access route that reaches its target without canonical sensory receptor transduction, whether by physical neural interaction, biochemical or pharmacological engagement, or indirect non-sensory physiological mediation.
scope note: An asserted bypass route positively identifies such a route; it does not prove the technique is non-sensory, because a hybrid may also declare an intended sensory route. Absence of a sensory type is not OWL negation.

Session Event
type: Class
subclass of: Activity
definition: One observed occurrence during the execution of a session, located by its offset on the timing context that delivered the stimulus. An event records what the delivering system did — starting, pausing, resuming, falling back to another engine, applying a safety limit — and never what a participant experienced, which is a participant observation.
scope note: Deliberately not a planned process: an event is observed during execution, whereas the session specification is the plan.

Session Event Type
type: Class
subclass of: information content entity
definition: A controlled category of occurrence during a session execution.

Session Instance
type: Class
subclass of: Activity
subclass of: Sensory Stimulation Intervention
definition: The record of an actual execution of a session specification, including timing, completion status, platform, and optional self-report. Append-only: never modified after creation.

Session Specification
type: Class
subclass of: information content entity
subclass of: Plan
definition: A complete, reproducible description of a specific intended execution of a preset, including user-defined overrides of preset defaults. The unit of scientific reproducibility: given a specification and a conforming engine, the acoustic output is fully determined.

Signal Rendering
type: Class
subclass of: information content entity
definition: How one signal is made to reach a subject through one channel: onto which renderable parameter, by which mechanism, and whether the result is physically present or perceptually constructed. A qualified relation rather than a bare link, because all three of those are properties of the binding and not of either end.

Signal Shape
type: Class
subclass of: information content entity
definition: A controlled information category naming the form of a time-varying signal: the periodic shapes (sine, square, sawtooth, triangle), an envelope, noise, or a sampled recording. One vocabulary serves two roles — the shape a signal has, and the waveform a rendering presents — because they are the same fact seen from either side.
scope note: Noise is a shape whose extent is wide rather than a special case: white noise is this shape across the audible range, band-limited noise the same shape bounded to an interval. A sampled shape is an asset rather than a function, so it carries a source, a licence and a checksum where a sine carries none.

Source Governance Record
type: Class
subclass of: information content entity
definition: An immutable record governing a research output used as evidence: source version and digest, custodian, access classification, consent/ethics basis or an explicit not-applicable determination, and permitted use scope, with generation time and a qualified responsible agent.

Stimulation
type: Class
subclass of: process
label: Estimulación @es
label: Estimulação @pt
label: Stimolazione @it
definition: A deliberately parameterized process in which structured physical energy, mechanical input, a chemical agent, or another controlled input is applied as a stimulus with a declared design intent to elicit, perturb, regulate, or probe an identified biological, sensory, or neural process. Mere exposure, administration, or energy transfer without that stimulation intent is insufficient. Classification does not assert excitation, conscious perception, response, benefit, or safety.
related match: http://snomed.info/id/122545008

editorial note: The direction is left undetermined on purpose. This class's definition admits any deliberately parameterized process applied to an identified biological, sensory or neural process, under which the SNOMED concept would be narrower. Its scope note instead describes a neutral umbrella over sensory stimulation and interventional neuromodulation, under which the two merely overlap, because the SNOMED concept subsumes procedural stimulation that is neither. That is the same definition-versus-scope-note divergence recorded for sensory stimulation and non-neural recipients in docs/ontology/SENSORY_STIMULATION_SENSE_REVIEW.md. relatedMatch asserts the association without asserting a subsumption that a definition-authority decision could invalidate; upgrade to narrowMatch if the definition text is ruled normative.

definition: A coarse, non-exclusive operational category summarizing how an input is introduced or an interface is positioned — for example external, transcutaneous, transcranial, implanted, or systemic. Detailed device, body placement, administration, and dose remain in the exposure profile.
scope note: Values are deliberately non-exclusive: a method may be external, transcutaneous, and transcranial at once. No approach tag is inferred from any other facet.

Stimulation Intervention
type: Class
subclass of: planned process
subclass of: Stimulation
definition: A specific, designed execution of a stimulation process with defined parameters, delivery, and intended effect. The neutral planned-process layer over sensory stimulation and neuromodulation interventions.

Stimulation Mechanism
type: Class
subclass of: information content entity
label: Mecanismo de Estimulación @es
label: Mecanismo de Estimulação @pt
label: Meccanismo di Stimolazione @it
definition: A controlled information category identifying a proposed neurobiological or psychophysiological pathway through which a stimulus may produce a measured response or intended effect. Mechanism assignments require separate evidence assessment.

Stimulation Parameter Kind
type: Class
subclass of: information content entity
definition: A controlled, modality-neutral category naming which delivery quantity a mid-session change acted on, such as the level, the carrier, or the modulation rate.
scope note: Kinds, not field names. A vocabulary of named product fields would bind SSTIM to one application's parameter list; these categories are meant to hold for an auditory, visual or haptic channel alike, and an implementation maps its own field onto the kind.

Stimulation Protocol
type: Class
subclass of: information content entity
subclass of: protocol
definition: A structured method specification for using one or more stimulation techniques toward an intended use, including composition rules, timing, parameter ranges, constraints, and cautions. The neutral protocol layer over sensory stimulation and neuromodulation protocols.

Stimulation Signal
type: Class
subclass of: information content entity
definition: A time-varying function with a frequency extent, a shape, and no modality: what is to be delivered, said independently of any sense it might be delivered through. A 10 Hz square wave is one signal whether it becomes an amplitude-modulated tone, a flickering light or a vibration.
scope note: Deliberately modality-free. The moment a signal acquires a carrier or a luminance it has become a rendering, which is a different entity. Its identity is what makes two channels comparable, so a signal shared between them is the assertion that they deliver the same thing.

Stimulation Technique
type: Class
subclass of: information content entity
definition: A reusable information-content category for a parameterizable stimulation method. Classification records the method's declared design intent and characteristic delivery, not that any response occurred.
scope note: The neutral technique layer over sensory stimulation and interventional neuromodulation techniques. Electrical, magnetic, acoustic, optical, thermal, and chemical stimulation are property-based views over this class, not primitive subclasses (ADR 0034 §4).

Stimulus Specification
type: Class
subclass of: information content entity
definition: An engine-independent description of a sensory stimulation, stating what reaches the subject in physical or perceptual units rather than the settings that make a particular engine produce it. Two implementations whose output matches realise the same stimulus specification, which is what makes them comparable.
editorial note: Most of the rendering layer this class needs already exists on sstim-ex:StimulusChannel: a delivery medium and a perceived modality held apart, and rate properties per rendering — hasFrequencyHz for a carrier or tone, hasFlickerRateHz for a visual rate, hasBeatFrequencyHz for a monaural or binaural difference frequency. What is missing is the shared signal that ties them together. When one specification targets 10 Hz through an audio channel and a visual one, each channel states its own decimal and nothing asserts they are the same 10 Hz, so a consumer must infer identity by comparing numbers — and the comparability this class exists to provide is exactly what goes unstated. hasFrequencyHz also carries two roles at once, a carrier or a tone frequency, so a 10 Hz tactile vibration and a 200 Hz audio carrier use one property for different things. When the shared signal is added, keep the physical/perceptual distinction at the rendering layer: an isochronic tone and a visual flicker put a real modulation into the world, a binaural beat does not, and evidence does not transfer freely between them. See SSTIM_DIRECTIONS.md §5.
scope note: Not a sstim:Preset, which is engine-dependent by nature, and not a prov:Plan: a plan is something to be carried out, while this states what is or would be the case. It asserts nothing about effect — evidence, intended outcome and safety metadata are authored by a human through the gated catalog bridge and are never inferred from parameters.

Stimulus Temporal Structure
type: Class
subclass of: information content entity
definition: The temporal organization of an applied stimulus or agent. Values cover carrier periodicity (periodic, quasi-periodic, aperiodic), closed-loop adaptation, discrete event and pulse-train patterns, and administration schedules. Values are non-disjoint and may be combined, because carrier periodicity, pulse pattern, and administration schedule are different temporal features. Detailed executed timing remains in the exposure profile.

Study Design
type: Class
subclass of: information content entity
definition: The design of the underlying studies contributing to an evidence source (for example randomized controlled trial, observational, case report, preclinical experiment, mixed, or unknown).

Study Model
type: Class
subclass of: information content entity
definition: The model or stage in which an evidence source's findings were produced (for example human participants, preclinical animal model, in vitro, computational).

Symmetry Voice
type: Class
subclass of: Voice
definition: N notes log-distributed over I octaves, repeated with algebraic group permutation at each cycle boundary, at pulse rate N/d Hz. When I=0, reduces to traditional isochronous tone stimulation.

Timing Authority
type: Class
subclass of: information content entity
definition: A controlled category identifying which timing surface produced a session's event offsets, so a consumer can tell whether they came from audio hardware or from a substitute clock.

Track
type: Class
subclass of: information content entity
definition: A single layer within an engine configuration, carrying the parameters that specify what that layer contributes to the arrangement. A track is exactly one of audio, visual, haptic or control.
scope note: The generic superclass for audio, visual, haptic, and control layers. The optional Patch Studio profile specializes sstim:Voice under sstim:AudioTrack; other configuration schemas may define their own Track subclasses. ADR 0041 renamed the former Patch Studio control voices to LFO and Permutation before adding that Voice subsumption, removing the earlier audible-versus-control ambiguity.

Unwanted Experience Category
type: Class
subclass of: information content entity
definition: A controlled, non-diagnostic category describing an unwanted experience in the participant's own terms.

Unwanted Experience Observation
type: Class
subclass of: information content entity
definition: One unwanted experience as described by the participant: a controlled category, the severity they reported, when it began, how long it persisted, what they did about it, whether it resolved, and whether they perceived it as related to the session.
editorial note: Deliberately not named or modelled as a side effect or adverse event. Both terms assert a causal or clinical conclusion that a participant report cannot establish, and using them would make every record of ordinary discomfort read as a safety finding.

Visual Track
type: Class
subclass of: Track
definition: A track whose output is visible. Rate-bearing visual tracks are subject to the runtime flash-rate safety limits recorded in the exposure module.

Voice
type: Class
subclass of: information content entity
subclass of: Audio Track
definition: An audio layer within a BSC catalog preset, identified by its technique type (Binaural, Martigli, Martigli-Binaural, Symmetry) and carrying the parameters that fully specify that voice. A catalog preset contains 1–6 voices.
scope note: The catalog-model specialisation of sstim:AudioTrack: every voice is an audio track, while an audio track in another schema need not be one of the four catalog technique types.

Voice Type
type: Class
subclass of: information content entity
definition: A named category of BSC audio voice (Binaural, Martigli, Martigli-Binaural, Symmetry) identifying the synthesis technique a voice realizes. Classification anchor for the SKOS voice-type vocabulary; distinct from the sstim:Voice parameter-bundle classes in Part 6.

Amendment activity
type: Class
subclass of: Ecosystem engagement activity
definition: An operational activity recording that an ecosystem relationship was amended, with the revision chain expressed using PROV. Invalidated values and the detailed amendment event remain in the private audit ledger; the public graph publishes only the approved current replacement.

Consent decision activity
type: Class
subclass of: Ecosystem engagement activity
definition: An activity recording a controlled consent outcome for one relationship and purpose. Raw consent evidence remains private and is not represented by this public summary.

Ecosystem agent
type: Class
subclass of: Agent
definition: A person or organization active in, or relevant to, the field of sensory stimulation, recorded in the SSTIM ecosystem. Instances are additionally typed with schema.org/FOAF person or organization classes. The class is evaluatively neutral: contributor, stakeholder, cited-author, peer-project, and similar roles are assigned to qualified relationship records with sstim-eco:hasRelationshipType, not asserted as global agent types.

Ecosystem record purpose
type: Class
subclass of: information content entity
definition: A controlled purpose for which an ecosystem relationship or engagement activity is recorded, such as public discovery, attribution, outreach, or live publication.

Ecosystem relationship
type: Class
subclass of: information content entity
subclass of: Entity
definition: A named, qualified record binding exactly one ecosystem agent to one target, relationship type, purpose, source set, curator, and review history so values cannot be cross-associated across several relationships.

Ecosystem engagement activity
type: Class
subclass of: Activity
definition: A named activity recording one lifecycle event for one ecosystem relationship, with a purpose, controlled outcome, timestamp, and responsible agent. The private operational ledger is append-only; only approved positive state is projected publicly.

Engagement outcome
type: Class
subclass of: information content entity
definition: A controlled minimal outcome of an ecosystem engagement activity. Positive admission outcomes may appear in the public current-state graph; negative and operational outcomes remain private. No outcome publishes correspondence, contact details, or raw consent evidence.

Implementation responsibility
type: Class
subclass of: Ecosystem relationship
definition: A qualified relationship identifying a person or organization that develops, publishes, maintains, provides, operates, hosts, or funds a specific sstim:SensoryStimulationImplementation.

Implementation responsibility type
type: Class
subclass of: Ecosystem relationship type
definition: A controlled relationship type identifying how a person or organization is responsible for a sensory-stimulation implementation, such as developer, publisher, maintainer, provider, operator, host, or funder.

Notification activity
type: Class
subclass of: Ecosystem engagement activity
definition: An activity recording that notification about an ecosystem relationship was sent or failed, without publishing its channel, address, or message.

Organization membership
type: Class
subclass of: Membership
subclass of: Ecosystem relationship
definition: A sourced, time-qualified relationship in which a person is a member of an organization in an identified ORG role. The member and organization also fill the relationship-agent and relationship-target positions.

Publication decision activity
type: Class
subclass of: Ecosystem engagement activity
definition: An activity recording whether a qualified ecosystem relationship is approved or withheld for publication under its declared purpose. In a public SSTIM ecosystem artifact, the chronologically final activity for every admitted relationship is an approval decision.

Ecosystem relationship type
type: Class
subclass of: information content entity
definition: A controlled category describing how an ecosystem agent relates to sensory stimulation or to SSTIM (e.g. contributor, stakeholder, cited author). Instances are the dual-typed SKOS concepts of the EcosystemRelationScheme.

Response activity
type: Class
subclass of: Ecosystem engagement activity
definition: An activity recording a controlled response outcome for an ecosystem relationship without publishing response text or private evidence. Only acknowledged is public-safe; change, objection, and removal outcomes remain private.

Withdrawal activity
type: Class
subclass of: Ecosystem engagement activity
definition: An operational activity recording a removal request or consent withdrawal for one qualified ecosystem relationship. The event is retained in the private audit ledger while the withdrawn relationship and identifying public chain are removed from the current public graph.

Audio Noise Color
type: Class
subclass of: Stimulus Pattern
definition: Controlled vocabulary class for named audio-noise color conventions. Names vary across communities and should be defined by spectral slope when possible.

Biohacking Context
type: Class
subclass of: Experiment Context
definition: Experiment context for exploratory self-observation, sensory experimentation, or non-clinical biohacking practice.

Body Placement
type: Class
subclass of: information content entity
definition: Controlled vocabulary class for where a device, medium, or exposure is placed on, in, or near the body.

Boundary Applicability Statement
type: Class
subclass of: information content entity
definition: A reasoned statement that a named comfort or safety boundary or exposure limit applies to a profile or channel. An applicability judgment, not an evidential finding.

Comfort Boundary
type: Class
subclass of: information content entity
definition: A boundary or caution condition for comfort, discomfort, awareness, fatigue, or risk during an exposure.

Device Capability
type: Class
subclass of: information content entity
definition: Controlled vocabulary class for hardware or environmental capabilities required to deliver, separate, sense, or shape an exposure.

Effect Dimension
type: Class
subclass of: Evidence Outcome Concept
definition: Controlled vocabulary class for comfort, risk, perception, and physiological dimensions that a hypothesis, research question, design objective, or planned outcome can concern. A subclass of sstim:EvidenceOutcomeConcept (ADR 0027), so existing dimension values are reusable as outcome concepts without ad hoc dual typing.

Experiment Context
type: Class
subclass of: information content entity
definition: Information artifact describing the local context of an exploratory protocol or exposure example.

Exploratory Protocol
type: Class
subclass of: information content entity
subclass of: protocol
definition: Non-clinical protocol used to explore an exposure idea, capability boundary, or perceptual hypothesis without asserting treatment, diagnosis, cure, or guaranteed effect.
scope note: Deliberately not a subclass of any stimulation protocol: a baseline defined by the absence of stimulation, or a mere-exposure hypothesis, must not become stimulation by inheritance. An exploratory protocol that is genuinely stimulation declares that type explicitly (ADR 0034 §7).

Exposure Design Objective
type: Class
subclass of: information content entity
definition: A desired delivery capability or experience that does not predict an observed effect. Any empirical expectation belongs in a separate hypothesis.

Exposure Effect Claim (deprecated)
type: Class
subclass of: Evidence Claim
deprecated: true
definition: Deprecated ADR 0027: this class mixed hypotheses, questions, boundary applicability, requirements, design objectives, planned outcomes, and status assertions under evidence semantics. Its instances migrate to the role-specific statement classes; removed no earlier than 1.0.
history note: Deprecated 2026-07-13 by ADR 0027; the 27 live instances migrate per the ADR 0027 migration ledger.

Exposure Hypothesis
type: Class
subclass of: information content entity
definition: A testable proposition asserting an expected relation, difference, or direction for an exposure. Not evidence: it carries no tier, direction, basis, or review metadata and can never satisfy an evidence-assessment shape.

Exposure Limit
type: Class
subclass of: information content entity
definition: A quantified safety limit for an exposure, such as a maximum flash frequency, a sound-level dose, or an optical-radiation exposure boundary. An exposure limit carries a value and/or maximum frequency, an optional averaging time and body placement, and should cite the external standard it is derived from. It does not itself assert that any specific delivery is safe; it records the threshold against which a delivery is checked.

Exposure Measurement Requirement
type: Class
subclass of: Protocol Requirement
definition: A protocol requirement identifying the exposure quantities and sensor capability that must be measured or recorded.

Exposure Profile
type: Class
subclass of: information content entity
definition: Information artifact describing how one exploratory or operational stimulation exposure is delivered, perceived, placed, bounded, and interpreted.

Knowledge Status
type: Class
subclass of: information content entity
definition: Local status vocabulary for distinguishing known SSTIM patterns, hypotheses, unknowns, lack of known SSTIM evidence, and BSC Lab capability boundaries.

Knowledge Status Activity
type: Class
subclass of: Activity
definition: The PROV activity that generates a knowledge-status assertion, recording time, method/corpus revision, and a qualified responsible agent/role.

Knowledge Status Assertion
type: Class
subclass of: information content entity
definition: An immutable, scoped, dated assertion assigning an existing controlled KnowledgeStatus value to an identified subject: exactly one subject link, one status value, one as-of date, and a named corpus scope or scope note. It states what a named corpus records as of a date — never a universal claim — and carries no evidence tier, direction, basis, or review metadata.

Perceived Modality
type: Class
subclass of: information content entity
definition: Controlled vocabulary class for the sensory, perceptual, behavioral, interoceptive, or social-perceptual channel engaged by an exposure.

Perceptual Gain
type: Class
subclass of: information content entity
definition: A perceived capability, salience, immersion, or access gained by an exposure setup.

Perceptual Loss
type: Class
subclass of: information content entity
definition: A perceived field, awareness, comfort, capability, or certainty lost or reduced by an exposure setup.

Physical Delivery Medium
type: Class
subclass of: information content entity
definition: Controlled vocabulary class for the physical medium, energy, material, or environmental interface through which a stimulus or exposure reaches a person.

Planned Outcome Specification
type: Class
subclass of: information content entity
definition: A dimension and collection/comparison plan for an exposure — what would be collected and compared, not an observation result.

Protocol Requirement
type: Class
subclass of: information content entity
definition: A reproducibility, measurement, context, or study-design requirement constraining a protocol, profile, or channel.

Research Question
type: Class
subclass of: information content entity
definition: An open question about an exposure that asserts no expected result.

Stimulus Channel
type: Class
subclass of: information content entity
definition: A channel within a stimulus specification or exposure profile, such as an audio, visual, haptic, respiratory, olfactory, gustatory, or electromagnetic exposure path.
editorial note: The paths named here are asserted by sstim-ex:perceivedModality and sstim-ex:deliveryMedium, which hold apart the sense a channel engages and the physical medium that reaches it. Note that SSTIM carries two modality vocabularies with different intensions: sstim-ex:PerceivedModality names the channel an exposure engages, twelve values including proprioceptive, gustatory, multimodal and not-directly-perceived — the last two are not senses at all — while sstim:SensoryModality names a sense, six values. The six they share are bridged by skos:closeMatch from the exposure side, deliberately close rather than exact because the intensions differ. Choose by role: a channel engages a perceived modality; a technique or an assessment scope is about a sensory modality.

Stimulus Channel Role
type: Class
subclass of: information content entity
definition: A controlled category for the part a stimulus channel plays in an exposure: an intended causal intervention path, an associated concomitant exposure, a control or sham path, or a feedback path.

Stimulus Pattern
type: Class
subclass of: information content entity
definition: Controlled vocabulary class for temporal, spatial, color, or stochastic stimulus patterns.

Visual Noise Type
type: Class
subclass of: Stimulus Pattern
definition: Controlled vocabulary class for visual noise, visual field, and simple visual stimulus types.

definition: Accessibility safeguard derived from WCAG 2.2 success criterion 2.3.1 and ITU-R BT.1702: content should not exceed three general flashes or three red flashes in one second unless the applicable below-threshold test is satisfied.

limit value: 85
definition: NIOSH occupational recommended exposure limit of 85 dBA as an 8-hour time-weighted average, with a 3 dB exchange rate (each 3 dB increase halves the recommended duration). This occupational limit is not a general-public listening recommendation. BSC Lab cannot measure delivered sound pressure level and treats this record as advisory rather than a safety guarantee.

definition: ICNIRP daily exposure limit of 30 J/m2 spectrally weighted effective ultraviolet radiant exposure for unprotected skin and eye, calculated over 180-400 nm. IEC 62471 supplies lamp photobiological risk classification; it is not the source of the 30 J/m2 value. BSC Lab does not deliver ultraviolet radiation at the body.

SSTIM Frequency Band Vocabulary
type: NamedIndividual
type: ConceptScheme
description: Controlled vocabulary of named frequency ambits — Hz intervals — used in BSC protocol design for targeting and evidence classification. An ambit is not a rhythm: the named neural oscillations are sstim-v:NeuralOscillationScheme, and each points here through sstim:hasTypicalFrequencyBand. BSC operational taxonomy — not a medical diagnostic taxonomy.
license: https://creativecommons.org/licenses/by/4.0/
editorial note: Resolved 2026-08-15 (ADR 0049). The earlier note here recorded a suspected conflation between an observed-EEG-oscillation sense and a stimulus-frequency-target sense of these concepts, deferred pending a dedicated ADR. The suspicion was mistaken: a band is a Hz interval throughout — sstim-v:alpha10 and sstim-v:gamma40 sit in this same scheme and name no rhythm — and a band does not change identity by being aimed at, since it is the relation sstim:targetsFrequencyBand that makes one a target. What was missing was a term for the rhythm itself, now sstim-v:NeuralOscillationScheme. The outcome associations that used to sit in the per-band scope notes moved to those rhythms as evidence claims or as dated knowledge-status assertions where no evidence was found.

scope note: This scheme replaces any single target-level axis. A route, a dynamic, a system, and an outcome domain are not values on one scale, and an autonomic outcome can also be neural. Perceptual, cognitive, motor, physiological, and behavioural outcome domains are modelled separately and non-exclusively; a controlled vocabulary must not force false partitions to simplify a query.

scope note: A single coarse ordinal-ish axis, deliberately orthogonal to route, approach, target site, system, and phenomenon (ADR 0034). Engagement mode is a property of the method, not a claim about efficacy, and does not by itself decide whether a method is neuromodulation (ADR 0035).

history note: Relabelled in 0.9.0 (ADR 0034). The scheme IRI has always been sstim-v:TechniqueScheme, never SensoryTechniqueScheme, so only the label was narrower than its own identifier; this brings the label into line rather than widening the scheme. Precision moved to the definition, which keeps the label stable against future widening. Cataloguing a technique means SSTIM can describe it, never that BSC Lab delivers it.

Alpha
type: NamedIndividual
type: Concept
type: Frequency Band
Hz maximum: 13
Hz minimum: 8
broader: All Frequency Bands
definition: A named frequency interval, 8–13 Hz: the interval the alpha rhythm is delimited by. A conventional ambit rather than a natural boundary — the edges are agreed rather than observed, and differ between sources. It is a Hz range and nothing more; the rhythm delimited by it is a separate term (ADR 0049).
history note: External mapping moved 2026-08-15 (ADR 0049): wd:Q2469782 describes a neural oscillation, not a Hz interval, and now maps to sstim-v:alphaOscillation. This band is reachable from that concept through sstim:hasTypicalFrequencyBand.

Alpha 10 Hz
type: NamedIndividual
type: Concept

Hz maximum: 10
Hz minimum: 10
broader: Alpha
definition: A single-frequency target, 10 Hz exactly: a single frequency inside alpha. A conventional ambit rather than a natural boundary — the edges are agreed rather than observed, and differ between sources. It is a Hz range and nothing more; the rhythm delimited by it is a separate term (ADR 0049).
in scheme: SSTIM Frequency Band Vocabulary
notation: alpha-10
preferred label: Alfa 10 Hz @es
related: High Alpha
related: Low Alpha
scope note: The canonical 10 Hz stimulation target (Berger's classic alpha peak / typical individual alpha frequency). Distinguished from broad alpha because multiple protocols specifically target this frequency. It names a delivery target, not a rhythm and not an outcome: what targeting it is claimed to do is recorded against sstim-v:alphaOscillation with a tier and a source, or as a dated knowledge-status assertion where none was found. 10 Hz sits exactly on the shared boundary of the two alpha sub-bands — the inclusive upper bound of low-alpha (8–10 Hz) and the inclusive lower bound of high-alpha (10–13 Hz) — so it is associatively related (skos:related) to both, not filed under either. skos:related is used rather than a cross-scheme mapping property such as skos:broadMatch because all three concepts are in this same scheme.

editorial note: Added 2026-08-18 (ADR 0025 decision 5). Without it a stimulus that steps between values mid-session could only be described by flattening it into one row, which that decision forbids. A modulation the specification already declares in full stays declarative and is rendered as a linked trace; this type is for changes the plan does not contain.

definition: A named frequency interval, 12–15 Hz: the sensorimotor interval, overlapping both alpha and beta. A conventional ambit rather than a natural boundary — the edges are agreed rather than observed, and differ between sources. It is a Hz range and nothing more; the rhythm delimited by it is a separate term (ADR 0049).

scope note: "Rhythm", "wave" and "oscillation" name this same entity interchangeably, but they are near-synonyms rather than exact ones and are not substitutable in general: an oscillation is the rhythmic fluctuation itself; a wave is how it appears in a recorded signal, a word EEG also uses for deflections that are not oscillatory at all such as a P300 wave or a K-complex; and a rhythm is an oscillation regular enough to be named and tied to a state or generator, which a transient oscillatory burst is not.

intended neural target site: peripheral nervous system
neural access route: canonical sensory transduction and afferent access
participant engagement mode: Active / Self-Regulatory
stimulation delivery approach: external
characteristic delivery medium: air-conducted sound
characteristic delivery medium: visual light
definition: A closed-loop practice in which a measured physiological signal (heart rate, heart-rate variability, respiration, muscle tension, or skin conductance) is rendered back to the individual as sensory feedback so that they can learn to self-regulate that function.
editorial note: Added from the 2026-07-22 Theo Marins interview; typed as self-directed neuromodulation by ADR 0036.
editorial note: Deliberately kept as one neutral technique rather than split into narrower neural-only and peripheral-only variants (ADR 0037, RDF-05 of the 2026-07-24 audit): the neural-modulation objective is not equally definitional across its autonomic, muscular, and electrodermal forms, so a narrower neuromodulation-only subtype would misrepresent the peripheral cases. sstim:techNeurofeedback already exists as the separate, narrower technique for which the neural-modulation objective is definitional.
in scheme: SSTIM Stimulation Technique Vocabulary
notation: biofeedback
related: Sonification / Auditory Biofeedback
scope note: Self-directed neuromodulation (ADR 0036), marked by the active-self-regulatory engagement mode. Its neuromodulation status is clearest for autonomically mediated forms — heart-rate-variability biofeedback trains vagal and baroreflex regulation; peripheral forms such as EMG muscle biofeedback sit closer to motor self-regulation than to neural modulation, so the neural target is recorded broadly. Auditory biofeedback is the sonification case (sstim-v:techSonification); HRV/paced-breathing biofeedback connects to BSC's Martigli breathing component. Theo Marins (2026-07-22) placed biofeedback closer to neuromodulation than to neurostimulation, which ADR 0036 adopts.

editorial note: Catalogued for transparency. SSTIM's curated corpus has not assessed a tuning-specific physiological effect for 432 Hz reference-pitch retuning (small unidentified pilots exist, so 'no evidence recorded' would overstate the corpus scope) — a corpus-scoped status, not a universal claim; see the scoped KnowledgeStatusAssertion at bsclab-evidence:reference-pitch-432-inconclusive/status/1 (ADR 0027).

Parametrize a stimulus channel with sstim-ex:referencePitchNote / referencePitchHz / retunedFromReferenceHz / pitchShiftCents.

top concept of: SSTIM Stimulation Technique Vocabulary
evidence notes: Honest ceiling: tier 2-3, claim direction mixed/inconclusive. The few small double-blind crossover pilots (e.g. ~4.79 bpm heart-rate reduction for 432 vs 440 Hz, n=33) tested full transposed MUSIC, confounding absolute tuning with overall pitch-lowering and tempo, and none tested a 432 Hz carrier under a binaural/isochronic beat — a modality/population mismatch that discounts any transfer to BSC's use case. At least one 2025 athlete study found 440 Hz more effective for several outcomes. Audit citation venues before use.

type: NamedIndividual
type: Concept
type: Non-Entrainment Technique
has stimulus temporal structure: Periodic
intended neural phenomenon: frequency-following response
proposed mechanism: Vibrotactile Mechanoreceptor Activation
technique modality: Auditory
technique modality: Somatosensory
characteristic delivery medium: air-conducted sound
characteristic delivery medium: contact acoustic vibration
alternative label: vibroacoustic therapy
definition: Low-frequency sound delivered through body transducers, chairs, beds, or wearables, so it is felt as well as heard.

Vibrotactile Pulse Entrainment
type: NamedIndividual
type: Concept
type: Entrainment-Based Technique
has stimulus temporal structure: Periodic
intended neural phenomenon: somatosensory steady-state response
proposed mechanism: Vibrotactile Mechanoreceptor Activation
technique modality: Somatosensory
characteristic delivery medium: mechanical vibration
definition: Rhythmic vibrotactile pulses delivered to the skin (wrist, fingertips, torso, or a wearable) at a target rate to drive somatosensory cortical rhythms. The tactile counterpart of isochronic auditory entrainment; deliverable on consumer hardware via the Web Vibration API.

Theta
type: NamedIndividual
type: Concept
type: Frequency Band
Hz maximum: 8
Hz minimum: 4
broader: All Frequency Bands
definition: A named frequency interval, 4–8 Hz: between delta and alpha. A conventional ambit rather than a natural boundary — the edges are agreed rather than observed, and differ between sources. It is a Hz range and nothing more; the rhythm delimited by it is a separate term (ADR 0049).
history note: External mapping moved 2026-08-15 (ADR 0049): wd:Q2370623 now maps to sstim-v:thetaOscillation.

scope note: 4–8 Hz. The conventional ambit by which the theta rhythm is delimited; the rhythm itself is sstim-v:thetaOscillation.

Theta oscillation
type: NamedIndividual
type: Concept
type: Neural Oscillation Type
has typical frequency band: Theta

scope note: "Rhythm", "wave" and "oscillation" name this same entity interchangeably, but they are near-synonyms rather than exact ones and are not substitutable in general: an oscillation is the rhythmic fluctuation itself; a wave is how it appears in a recorded signal, a word EEG also uses for deflections that are not oscillatory at all such as a P300 wave or a K-complex; and a rhythm is an oscillation regular enough to be named and tied to a state or generator, which a transient oscillatory burst is not.

editorial note: Upgraded from closeMatch on the band to exactMatch on the rhythm (ADR 0049). The item describes a neural oscillation, which is what this concept now names; the earlier closeMatch was forced by the subject being a Hz interval. Quoted numeric bounds differ only as delimiting conventions differ.
