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 from it is derived

MusicBrainz stores ISWCs for works.
