[uf-discuss] a microformat for audio track metadata

[Chris Messina]

One other thing to consider w/r/t to using "rel" is how we mark up
media in a webpage. We've got embed and object, of course, but I want
to see a much more semantic way of embedding media in XHTML -- even if
we use those tags to get the actual media to be playable.

Here's my use case:

Record some audio. Save file to desktop. Want to podcast it. Open up
my blog editor, drag and drop media file into the post. Hit "publish".
The media file gets sent up to a repository in the sky and ends up
both as an RSS enclosure as well as a "play button" on my blog.

Pulling in rich meta data from the ID3 tags would also be nice... or
allowing me to add data around the file, like:

Track: My stupid dog
Artist: Some rock band
[   play button   ]

So if we can mark that up some standard way AND allow people to view
the media in situ, that would rock. Literally.
