The rating system was introduced with the November 23rd, 2008 server release, and is a feature that allows users to rate MusicBrainz entities (artists, labels, releases and tracks).
User may assign a value between 1 and 5 to various entities as a rating, these values are then aggregated by the server to compute an average community rating for that same entity.
The community rating is shown by default for each entity, however, once a user submits their own rating that value will be shown instead.
Display of ratings can be disabled in User Preferences for those who prefer not to use or see ratings.
The two methods of submission/retrieval are:
- Using the new /rating resource for submitting/retrieving one specific rating.
wget --user=<editor name> --password=<password> --post-data=id=8f6bd1e4-fbe1-4f50-aa9b-94c450ec0f11\&entity=artist\&rating=3 http://test.musicbrainz.org/ws/1/rating
- Using the two new inc parameters with the artist, label, release or tracks resources as described in XML Web Service.
