From MusicBrainz Wiki
- An artist is generally a musician, group of musicians, a collaboration of multiple musicians or other music professionals who contribute to works described in the MusicBrainz Database. They can also be a non-musical person (like a photographer, an illustrator, or a poet whose writings are set to music), or even a fictional character.
- Artist credits are a list of artists, variations of artist names and pieces of text to join the artist names.
- An organised event which people can attend, and is relevant to MusicBrainz. Events generally refer to live performances, like concerts and festivals.
- Labels are generally imprints on releases, and to a lesser extent, the record companies behind those imprints.
- Places are areas smaller than a geographical region (like a building or an outdoor area) used to perform or produce music. It could range from a stadium to a religious building to an indoor arena.
- Recordings are unique audio data. It has a title, artist credit, and duration. Recordings can be linked to tracks on releases. Each track must always be associated with a single recording, but a recording can be linked to any number of tracks.
- Releases are real-world release objects (like a physical album) that you can buy in your music store. When a musical product is issued on a specific date with specific information such as the country, label, barcode and packaging, it is a release.
- A medium is a piece of media included in a release. It contains information about the format, position in the release and an optional title as well as a list of tracks. Several media exist, including but not limited to: CD, 12" vinyl, digital media. A medium normally has a tracklist.
- A track contains a link to a recording, title, artist credit and the position on the medium. A track is different from a recording in that it is unique to a release; a number of different releases can contain the same recording.
- Release groups are an abstract "album" entity. Technically it's a group of releases, with a specified type.
- A series is a sequence of separate release groups, releases, recordings, works or events with a common theme. The theme is usually prominent in the branding of the entities in the series and the individual entities will often have been given a number indicating the position in the series.
- A URL represents a regular Internet Uniform Resource Locator and an associated description of that URL.
- A work is a distinct intellectual or artistic creation, which can be expressed in the form of one or more audio recordings. While a recording represents audio data, a work represents the composition behind the recording.
