Introduction

The MusicBrainz database stores all the data of the MusicBrainz music metadata catalogue. This data includes information about artists, release groups, releases, tracks, labels and relationships between them. It also contains information about the MusicBrainz users (editors) and the changes they have entered into the database (edits).

Each of these Artist, Release, Track and Label entities can be linked with Advanced Relationships that provide a rich tapestry of data relationships. Advanced relationships provide information about web resources (e.g. Wikipedia pages, download locations, etc) for entities and they can indicate instrument/vocal performances on a piece of music. These relationships allow MusicBrainz to capture most of the data contained in the liner and liner notes for an Audio CD. For more details on these relationships, please read our Advanced Relationships page.

Download

The MusicBrainz database is built on the PostgreSQL relational database engine. Therefore the data files are provided in the PostgreSQL "COPY TO" format, only really suitable for restoring to a PostgreSQL database. See the Database Schema documentation for a description of the schema, and what each of the tables are used for.

see the Database Download page for instructions on how to download the dumps.

Installation

There are a few contributed guidelines how to setup the database on different systems. See Database Setup for the list of available documents. The easiest way to get a running database is to install a Virtual MusicBrainz Server.

License

The data collected by the MusicBrainz project is made available to the public under open licenses. Some of the data is available under the Public Domain, and some under the Creative Commons Attribution-NonCommercial-ShareAlike license (See MusicBrainz License for more details).

Live data-feed (or Replication)

The live data-feed enables a server running a PostgreSQL database in conjunction with the MusicBrainz Server to automatically stay in synch with the main server (See Live Data Feed for more details).
