I have been (very slowly as my dad is in hospital following a major stroke and 20 minutes for me immersed in MB has become a wonderful luxury) adding works found in
Many of these works are from old manuscripts c. 1500.
The current style guidelines read; Note: In general you should only add a collection if the composer was involved. Do not enter things like "All piano sonatas by Beethoven" as works in MusicBrainz.
Can see the danger of having Beethoven's 5th Symphony being linked to 12,000 publications of the work.
However I think that having the relationship between a recording of a circa 1480CE work and the collection of works in which it found, the Cancionero Montecassino, adds a significant aspect to the recording metadata. I would easily be able to find other recordings of works from that manuscript. And future editors could benefit from having possible confusions around works in that manuscript being flagged.
Are there other ways of avoiding the dangers of having "collections of works" in the database, while getting the benefits?
Very open to other views.
(And suggestions of how to describe the relationship between work and collection.)
