That does sound good to me. Let's see if there are comments on this.
Also if you or anyone else can think of other relevant DBs (discogs
for music ? musicbrainz ? amazon store ?). Maybe an accompanying URL
or at least DNS for the service could be good. Maybe the DNS as the
tag name ? There could be an issue if one DNS have 2 different DBs (ie
IDs not matching in the 2 different DBs) for music and video.
