Well, musicbrainz is great, but it won't identify actors
(for example). More generally for organisation internal
metadata where you might want to say 'Bob recorded this'
musicbrainz is never going to give you an ID unless Bob
also happens to be a successful recording artist. You
could use an organisation internal ID scheme of course;
a new band releasing a track online still faces a problem
Actually it might be instructive to bring up (some of!)
the tags from a file that I have on my hd:
All capitalised tags are the result of an MB automatic
tagging tool. The MB one includes all the uuids, but
also pulls in a 'sortname'. (Incidentally the album name
had been added when encoding, I suspect that's why it was
unmodified.) Despite UUIDs there's an acknowledgement
here that you don't want to have to query the MB database
every time you want to search your music collection, the
UUID's main feature as far as I can see is to help tie
the database together at their end.
What I think would be useful would be a way of specifying
names which makes it easier to do structured sort.
Having separate first name(s) and last name fields would
work for most cases, but a vCard-like sortname field is
probably more realistic. Make the sort name a mandatory
part of the name description and suggest to application
developers how it should be used.
