Recordings are unique audio data. Has title, artist credit, duration, and ISRCs.
Release
Releases are real-world release objects (like a physical album) that you can buy in your music store.
Release Group
Release groups are an abstract "album" entity. Technically it's a group of releases, with a specified type.
Series
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.
Track
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.
URL
A URL represents a regular Internet Uniform Resource Locator and an associated description of that URL.
Work
One layer above recordings ("song", "composition", etc.). While recording represents audio data, work represents the composition behind the recording.
