The idea is to have a ranking of artists, based on partly objective criteria. The reason for this is more fun to clean up artists (like: I want to have my favorite band be fully cleaned up, and let others know). These artists are then also a show case what can be achieved with the full level of MusicBrainz interlinked data!
The proposed criteria are (only for artists that have a discography):
- unknown: default
- bronze: has "full" discography on overview page (release groups cleaned up), all artist relationships (performs as, band members) set, IPI set for artist and/or all band members
- silver: all releases/release groups cleaned up (date, label, barcode, ASIN/discogs links)
- gold: all recordings cleaned up (comments for live recordings / recordings with same name, identical ones merged), works cleaned up, every recording is associated with at least one work, all works have ISWC if they have any
- platinum: all external links set (lyrics, allmusic, discogs, ASIN, ...), all relationships set (writer, composer, ...); in this state nothing more can be done for the artist, except when musicbrainz gets new features or new releases appear.
