Agenda of the Plenary Sessions

• 2026, June 25th, AI Preference Signals This session will examine the fine-grained acceptance of content usage through IETF signals once a content provider has reserved their Text and Data Mining (TDM) rights via TDMRep. Our discussion will focus on the proposed vocabulary:
  • The current IETF draft defines the terms AI Model Training and Search.
  • Other proposed terms related to AI inference: AI Grounding, AI Input, and AI Remix. The goal of the plenary is to collect feedback on the central question: is this the specific vocabulary that publishers really need?

• 2026, may 28th, incubation & standardisation.
  Following recurrent discussions going back and forth between Community and Maintenance WG, challenging how topics are incubated before becoming part of the EPUB specification, we will hold a plenary discussion on this workflow. This discussion will build on the GitHub thread “Incubation of features and Ideas vs. adding them to the Spec” to clarify when issues are better handled by the CG and when they should move to the WG. During the plenary, we will collect concrete ideas, expectations, and next steps from both implementers and content creators, with the goal of establishing a clearer and more predictable path from incubation to specification changes.

• 2026, april 23th. Anti-counterfeit options for publishers. We will host presentations of available services and explore practical approaches to detection, response, and prevention.
  • Anna Berthod (1D345 Compilatio - https://www.compilatio.net/),
  • Titusz Pan (Amlet - https://amlet.ai/),
  • Sebastian Posth (Liccium - https://liccium.com)

• 2026 february 26th. discussion on parallel content in EPUB, building on the explainer “Parallel Content” and the GitHub discussion “Ways to publish and consume parallel contents”. The goal is to collect concrete use cases and requirements from content creators and implementers, and to discuss whether and how this work should evolve into a dedicated EPUB WG task force.

• 2026 January 29th: We will discuss what the W3C Web Publications format is suitable for and explore its distinction from EPUB and other formats — in other words, under what conditions it is the best option. We would love to hear testimonies from professionals who are using or considering the use of the Web Publications format. Please come and join us!
