We have posted some ePub samples on the AZARDI resource page to enable publishers to possibly understand and evaluate the various transition issues when making decisions about when to move to ePub 3, and how.
The samples include four Gutenberg books processed as ePub2, ePub3+2 (transitional) and ePub3 directly out of IGP:Digital Publisher. I could have added a KF8 mobi as well but that would have been showing off, and AZARDI doesn't like them.
The most interesting issue with these ePub variants is how they work on various readers - the reason for this evaluation set. It helps to set a baseline of understanding the issues.
Cover treatment is probably the biggest issue, but ePub 3 also has a cute little landmarks section that will only be seen in AZARDI right now.
We uploaded an informational demonstration book to the AZARDI download location today. EPUB3 UNLEASHED is a highly interactive ePub3. The book is pure HTML5, CSS3, SVG, MathML and Javascript.
AZARDI is designed for the controlled channel delivery of interactive content. It is optimized for specialist vertical channel content rather than being "just another reader". This demonstration starts to demonstrate what is possible.
One of the motivations for producing this was to show that the core technologies can deliver a lot more than anything that is in the market at present, and it can do it easily and cost effectively. The IGP:FoundationXHTML that is packaged into an ePub3 here can also be delivered as a Web Site and WebApp (with the exception that Android doesn't handle SVG!)
