EPUB 3 was just announced this morning by the IDPF. The final draft of standard being readied for release at BEA 2011. http://idpf.org/epub/30 – public release of standard here, ready for comment, looking for lots of comment/feedback from the international community. They have a great “human readable” document to give everyone an overview/introduction of what this is.
A few items of interest from the presentation are below. Lots more tweets at #toccon
Accessibility Issues – DAISY consortium have been an integral part of the development of EPUB 3. Accessibility features are woven throughout EPUB 3. Some key features: reading order will be well defined, ability to use navigation center to go to different areas of the book, page numbering that is aligned with the print counterpart, semantic structure will be enriched.
Metadata side of things – this standard is designed to be backwards compatible. New model is built on Dublin CORE and uses a tiny subset of RDFA 1.1. Not just books! This will work with other formats too – newspapers, magazines, etc.
Multimedia – now have a way to embed multimedia into EPUB. Also inheriting richer multimedia – MathML, SVG, allow more of the app like experience, etc.
