#  BSC Framework Vocabulary

#
#  The terms that belong to the BSC framework rather than to sensory
#  stimulation in general: the catalog's voice model, its five preset
#  groups, the parameterisation of the Martigli oscillation, and the
#  integer coding of Symmetry's permutation functions.
#
#  SSTIM ADR 0061 moved them out of SSTIM's universal namespaces. SSTIM
#  keeps each old term, deprecated, with dct:isReplacedBy pointing here.
#  The dependency runs one way: this vocabulary uses SSTIM terms, SSTIM
#  never uses these. It is part of no SSTIM profile or snapshot, and the
#  W3C Community Group that publishes SSTIM does not publish it.
#
#  What did not move: a parameter whose meaning holds without BSC stayed in
#  SSTIM. A Symmetry voice's note count, octave span and cycle are
#  sstim:noteCount, sstim:octaveSpan and sstim:cycleDuration; composition
#  and breath guidance are sstim:composedOfTrack and sstim:breathGuideTrack.
#  The Martigli parameters stay BSC's because each carries the catalog's
#  own bounds, but each is declared a sub-property of the generic SSTIM
#  breathing-oscillation term it specialises.
