If you are curious about the DAISY standard for Digital Talking Books, here’s a link to the equivalent DAISY 2.02 book, conveniently available online. I’m not sure why the online player does not work on my machine, please ask the developer if it’s the case on your machine too:

Please note that DAISY 3.0 makes use of NCX+DTBook instead of HTML+NCC, and that ePub is based on technologies derived from this latest DAISY standard.

Regarding the IDPF/OPS specs, here is a direct link to the DTBook part:

Finally, I’m pretty sure you’ll be interested in the DAISY-Pipeline project, which can be used to automate document conversion processes. They provide a desktop GUI as well as a command-line build, and they are currently working on a server-side implementation:

I do discuss DTBook briefly here, but you’re correct, Bookworm is presently XHTML-only.

I’d like to be able to support DTBook as well. I need to do some more reading on the format, but I also need some help from the community:

1. What would be best way to “support” it? Convert DTBook to XHTML internally and render those books in the browser like the XHTML-native ones? Or allow DTBook content to be loaded but defer to some kind of external text-to-speech application that understands DTBook already? Or something else?

2. I’ll need some ePub+DTBook content to test with, which I haven’t come across. (I could make my own, but it’s always preferable to use real content.)
