First Public Working Drafts: EPUB 3.3

 12 January 2021

The EPUB 3 Working Group has published four First Public Working Drafts today for EPUB 3.3. This technology defines a distribution and interchange format for digital publications and documents. The EPUB format provides a means of representing, packaging, and encoding structured and semantically enhanced Web content — including HTML, CSS, SVG, and other resources — for distribution in a single-file container.

The specification represents the third major revision and, in particular, a revision of the EPUB 3.2 document published by the EPUB 3 Community Group. This new version of the specification is now on a W3C Recommendation Track.

The four documents published by the Working Group are:

• The EPUB 3.3 specification defines the authoring requirements for EPUB Publications and represents the third major revision of the standard.
• The EPUB 3.3 Reading Systems specification defines the conformance requirements for EPUB 3 Reading Systems — the user agents that render EPUB Publications.
• The EPUB Multiple-Rendition Publications 1.1 specification defines the creation and rendering of EPUB Publications consisting of more than one Rendition. This document is not on recommendation track.
• The EPUB 3 Overview gives a high level overview of the EPUB 3.3 specification aimed primarily at non-technical readers. This document is not on recommendation track.

The Working Group welcomes comments via the GitHub repository issues.

W3C Advisory Committee Elects Technical Architecture Group

 

The W3C Advisory Committee has elected the following people to the W3C Technical Architecture Group (TAG): Amy Guy (Digital Bazaar), Sangwhan Moon (W3C Invited Expert), Theresa O’Connor (Apple, Inc.) and Lea Verou (W3C Invited Expert). They join co-Chair Tim Berners-Lee and continuing participants, Daniel Appelquist (Samsung Electronics; co-Chair), Rossen Atanassov (Microsoft Corporation), Hadley Beeman (W3C Invited Expert), Kenneth Rohde Christiansen (Intel Corporation) and Peter Linss (W3C Invited Expert; co-Chair). Yves Lafon continues as staff contact. Many thanks for contributions to the TAG to the departing participants, David Baron (W3C Invited Expert) and Alice Boxhall (Google), whose terms end at the end of this month.

The TAG is a special group within the W3C, chartered under the W3C Process Document, with stewardship of the Web architecture. The mission of the TAG is to build consensus around principles of Web architecture and to interpret and clarify these principles when necessary, to resolve issues involving general Web architecture brought to the TAG, and to help coordinate cross-technology architecture developments inside and outside W3C. The elected Members of the TAG participate as individual contributors, not as representatives of their organizations. TAG participants use their best judgment to find the best solutions for the Web, not just for any particular network, technology, vendor, or user. Learn more about the TAG.
