The following attributes can be used with this relationship type:
Use this to mark acts of an opera (as opposed to other parts that are not acts)
Use this when the parent work consists of several parts which are generally meant to be performed one after another in a particular order (rather than in any order, or multiple times, or in arbitrary selections rather than as a whole).
Use this for operas and similar works that are separated in numbers, to specify what parts are numbers (as opposed to spoken dialog or other non-numbered parts).
part of collection
Use this to indicate the parent work is not intended to be performed as a whole, but is just a grouping of pieces or works that can be performed individually (collections of songs, several sonatas or concertos published as a set, books of piano pieces, etc.)
This relationship should only be used for works where the composer split a work into multiple parts, not where a performer merely performed part of a work (often described as an excerpt, intro, or conclusion), instead see the 'partial' attribute of the Performance relationship.
For example, The Planets suite by Gustav Holst is broken into seven parts. Each counts as a work of its own (e.g. Mars, the Bringer of War), and is part of the aggregate work. The Planets, op. 32: Jupiter, the Bringer of Jollity (conclusion) is merely a partial recording of a discrete work, and doesn’t count as a work on its own.
Works for a part for which no recordings exist in MusicBrainz should be kept to a minimum. Some examples where this might be necessary:
- Accurately credit an artist, for example if Artist A wrote the lyrics for part I and artist B wrote the lyrics for part II, even though there are no recordings of part I or part II by themselves'.
- Provide a complete list of parts, for example if parts I and IV have recordings, but parts II and III do not.
Recordings which comprise multiple parts should be linked to all of their component works. Do not create additional works for every combination of parts. For example, if an artist records parts I and II of a work on one track and parts III and IV on another, do not create a work for parts I and II combined; just link the recording to the works for part I and part II.
