MusicBrainz Metadata Initiative uses Dublin Core-based metadata

The MusicBrainz Metadata Initiative was formed to organize a means of exchanging metadata describing media files on the Internet. The vocabulary developed is a Dublin Core-based metadata application and free web service that uses XML and RDF to make artist names, track numbers, song titles and other metadata describing musical content sownloadable to the user's CD player, MP3 player, Vorbis player or other client.
