ISWC

The International Standard Musical Work Code (ISWC) is an ISO standard similar to ISBNs for identifying musical works / compositions.

According to the Wikipedia article about ISWC, to register an ISWC, the following minimal metadata must be supplied:

• title
• names of all composers, arrangers and authors, with their role in the piece (identified by role code) and their CAE/IPI number
• work classification code (CIS (?))
• identification of other works it is a derivative of

MusicBrainz doesn't currently store ISWCs but could do so for composition objects in the planned NextGenerationSchema.
