Alas no. I did a lot of research and thinking about this last fall, but
haven't found time to implement anything. I remain excited about these
issues though, so I'd be happy to talk about your requirements and see
what can be done to help meet them.
See my recent summary on the vorbis-dev list and the resulting thread
for a rundown of metadata plans we have:
http://www.xiph.org/archives/vorbis-dev/0027.html
(or after the month is over, vorbis-dev/200104/0027.html)
Note that vorbis does have a working 'informal' comment system
that's
fairly broad as far as indexing metadata, more broad than id3 but not as
featureful as MusicBrainz or id3v2. It is however extensible for private
purposes. You can find a list of the standard tags in the vorbis
documentation:
http://www.xiph.org/ogg/vorbis/doc/v-comment.html
If you've also got transcripts or long lists of who did what kind of
engineering, you'll need a more capable format. My general thought is to
include xml-formatted text for that sort of thing: something like
MusicBrainz based on dublin core rdf-in-xml for "kitchen sink"
metadata,
something like my 'transcript' proposal for lyrics/subtitles/event
tracks:

Hope that helps,
