Re: Usage of the @role attribute (Fwd: IDPF event at Salon du livre)

Hi Robin,
thanks for your email and pleased to meet you too!

In general, I am interested in features that EPUB adds that aren't available on the vanilla "browser" web. I believe that those should provide use cases for additions to HTML. (Note that I'm not saying that HTML should just import them as is — but I do think that we should strive for convergence and I want to help with that.)

Glad to hear this -- and also agree that among the topics that relate to further harmonisation between EPUB and the OWP, usage of @role is just one of many items, and @role is not necessarily the sole or ideal solution the particular "problem" of structural inflection either. That said, @role is arguably the closest relative that we have for @epub:type in W3C space right now, so we are definitely interested in continuing this discussion.

Right. There are not many demoable implementations of specific reading system behaviours at this point (beyond the footnote behaviours in ibooks that everybody seems to know about). But there are several concrete (and general, as opposed to AT-specific) use cases for it in the pipeline, including as Ivan mentions the identification of structures such as glossaries, dictionaries and indexes. I will keep you updated as implementations emerge, both general and AT-specific.  

For now, /markus
