Hi uFers,
Based on work that was done in this community over a year ago, we've
attempted to do a port of hAudio over to the RDFa world. The result is a
set of 4 vocabularies for media, audio, video and commerce. We used a
number of Microformats principles when porting the vocabularies and
re-using pre-existing vocabulary terms. We re-use Dublin Core heavily.
The vocabularies can be found here:
http://purl.org/media/
http://purl.org/media/audio
http://purl.org/media/video
http://purl.org/commerce
A small plugin, named Fuzzbot, has been put together to explore semantic
web UI approaches and two demos are now up regarding the audio and video
vocabularies:
Intro to Fuzzbot and Audio Vocabulary

Intro to Video Vocabulary

The intros are very rough, done in 1-2 takes, but hopefully they get the
concept across. The next steps are going to be an attempt to use Firefox
3's Microformats functionality to pull uF metadata into Fuzzbot's RDFa
triple store.
Downloads and source for librdfa and Fuzzbot can be found here:

The Linux version is the only one that is up-to-date. I'll compile the
Mac OS X and Windows versions when I get the time to do so.
Feel free to comment/discuss the videos on here. We're looking for
feedback on what would make the demos more enticing. Right now, it's
just you can use metadata to construct more accurate searches.

PS: I also mis-spoke at one point in the first video and said that
before Fuzzbot it wasn't possible to do this sort of thing, which is
not correct 'cause Operator has been around for a much longer time.
Apologies to Mike Kaply, since he started blazing this trail some time
ago. :)
