Amongst the features of epub 3 is a possibility to insert accessibility tags to make the files more accessible for reading tools for handicapped. The possibility in 3.0 gets somewhat enforced in epub 3.1. No-one here at MobileRead seems to care much, and most of the ebooks I find "in the wild", that calls themselves epub 3 doesn't either. The only epub-creator tool giving the possibility to insert such tags (at least some of them) I have found are Jutoh.
But now there seems to be a new sheriff in town, so to speak, since the DAISY consortium are making an "accessibility checker" on the lines of epubchecker (
https://daisy.github.io/ace/), that are now in the release candidate stadium. I guess that the ebook-distributors will demand new epubs to pass this as well as epubcheck in some not-too-distant future.
Since we're producing solely epub 3-books here nowadays, we've reprogrammed our in-house tools to cather for this, but - are there any available tools except for Jutoh, that do this kind of thing?
Also, I've prepared an epub 3, that passes most of the ACE-tests. (It's a sample of an edition of a Maupassant short-story collection (in danish), and sort-of copyrighted, but since I myself is the copyright holder, and it will be free to download from our site from next monday, I guess it's allowable.) Feel free to play around with it - comments are welcome, I don't think it's in any way perfect …
