multipart, atompub, and a11y
Should I be thinking about the a11y
of atompub? A little red flag is up for me because of the discussion
about http://tools.ietf.org/html/draft-gregorio-atompub-multipart-00 Earlier,
on the list, I asked about if it would make sense to package alternative
media using the MIME type multipart/alternative, e.g. both visual and aural
representations to assist those who are deaf or blind respectively but
got back these responses:
- From Aristotle Pagaltzis: multipart/*
is forbidden as an Atom payload so you won’t find any such feeds.
- From Ernest Prabhakar: As mentioned,
Atom doesn't support multiparty. It does support multiple enclosures, though.
Are there any HTML conventions we could perhaps adopt to identify accessible
alternatives?
- From Brian Smith: My guess is
that multipart/alternative content would make things *less* accessible
today, not more accessible. My feed reader won't even display entries that
have multipart/alternative content and no tools (I know of) will help users
author entries as multipart/alternate
So I wasn't going to think about mutipart
any more and focus on file types like SMIL that have the alternative content
embedded. But maybe I still need to think about multipart. What
do you think?
