R2RML mappings for the MusicBrainz schema on an entity-by-entity basis.
These can be run on the MusicBrainz server using ultrawrap, for which a script is provided (dump.sh). (You must set an environment variable ULTRAWRAP_HOME)
Running musicbrainz-r2rml/dump.sh entity (where entity is artist, track, etc.) runs the appropriate set of mappings e.g. mappings/artist.ttl to produce output in the form of NTriples e.g. output/artist.nt
A virtual machine is available (for use with VirtualBox, VMware, etc.) with a replicated MusicBrainz database.
Note that the file musicbrainz_compile_config.properties must reflect your DB name:
- musicbrainz_db is the default for a snapshot
- musicbrainz_db_slave is the default for a replicated database
