John G,It's true that *most* of what EPUB 3 contains relates to HTML 5, but not all. For example, EPUB 3 now allows SVG documents in the OPF spine (making them part of the reading order), there are new elements for conditional content inclusion, there's CSS for defining list and content styles, and there are a whole slew of new bits and pieces - like scripting, TTS support, embedded fonts and the like - that need to be at least recognized and discarded. I'm not sure that these are "problems", but they need to be at least reviewed... A full list of the differences between EPUB 2 and EPUB 3 can be found at http://idpf.org/epub/30/spec/epub30-changes.html

Chris, I understand the new DAISY format, at least to some extent. We must certainly be able to import EPUB 3 into BrailleBlaster. That's not a big problem, since it is, after all, HTML. But HTML5 does include MathML andSVG, which we already intend to use. No problem there I trust.It is not quite so clear that we should also import DAISY 4. However ifDAISY 4 will be used to author DAISY with braille information, then weshould support it. It is my understanding that it will be used for thatpurpose, but I not 100% certain I am right.

The next version of DAISY uses ePub 3.0 (aka DAISY 4.0 Part B) as its distribution format, which is what most end users will end up with. There's a brief blurb about this in the DAISY Consortium 2010 Annual Report: "The convergence of the DAISY 4 distribution format with EPUB 3 will open up great opportunities for readers with print disabilities. It is our responsibility to continue our involvement in and influence on the implementation of fully accessible EPUB 3 in commercial e-books as well as in non-commercial information such as public information, information necessary for political decision making, and disaster preparedness information. The DAISY Consortium's endorsement of accessible EPUB 3 content will require an even greater effort by the Consortium in collaboration with print disability communities around the world, to influence the accessibility of mainstream e-book publications." http://data.daisy.org/publications/docs//ann_report_2010/AnnualReport2010.ht ml?q=publications/docs/ann_report_2010/AnnualReport2010.html On Jun 6, 2011, at 2:59 PM, Susan Jolly wrote:With a growing number of apps adding "Save as DAISY" options, I'd focus first on getting BrailleBlaster to work with DAISY files. If BrailleBlaster provides unique features that users need and can't easily obtain elsewhere then that should motivate them to find some method to convert any non-DAISY files to DAISY so they can use BrailleBlaster. Another important consideration is that the next-generation DAISY XML format known as ZedAI has already been developed and is currently under review. So this is not a good time to be investing a lot of resources in the old DAISY format. You can read more here: http://www.daisy.org/zw/ZedAI_UserDocumentation SusanJ
