[edit] Description
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).
[edit] Details
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.
[edit] Color Definitions

[edit] Web Service
The XML Web Service has been updated in order to allow to retrieve or update ratings via WS in a similar way to how folksonomy tagging works.
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.
