MusicBrainz is a user-maintained community music metadatabase. Music metadata is information such as the artist name, the release title, and the list of tracks that appear on a release. MusicBrainz collects this information about recordings and makes it available to the public. All of the data in MusicBrainz is user contributed and user maintained. This library is an interface to the MusicBrainz database. It is aimed at developers of media players, CD rippers, taggers and other applications requiring music metadata. The service's architecture follows the REST design principles. Interaction with the web service is done using HTTP and all content is served in a simple but flexible XML format. This package contains version 5 of the library.
