I haven't given up on editing operas either but haven't done much for the moment (there are still a lot of lower-hanging fruits first...).
My two eurocents:
I think Mozart operas shouldn't be a problem here. Most releases split tracks
nearly the same way around the arias or spoken sections. I would have
separate works for the spoken parts as ordered part works, with the first line explicitly quoted in the work title.
From my (limited) experience that's never the case for Die Zauberflöte or Don Giovanni where the spoken sections are always very short (< 2 minutes). Some releases skip completely the spoken parts also.
I added a few Wagner releases and they are much more annoying, with scenes ~20 minutes long without a clear and unique way to split, and all releases I found have their own way to split it in 3-6 minutes tracks.
I dislike the idea of linking all recordings to a "partial" scene, but I don't see how to do better...
Let me know if I can help, I would be happy to make things move forward
Indeed. My "guess related works" script can help, usually the track titles on opera are sufficiently explicit to find the right related work automatically.
One thing I have been thinking about for some time (but is not ready to be implemented) to make filling AR easier is to write a script that:
- takes the related work to determine the characters singing on a track
- looks at the corresponding singer in the release AR or release annotation
- fills automatically the singers (with voice range and character name) as recording AR
Of course I first need the track title to be complete with the right lyrics (so that the related work can be autoguessed easily) and the work title to contain the character names in a reliable way. Easier said than done...
One last point about Wagner, I wanted some feedback before trying: I thought about creating new works explicitly for excerpts of the opera played as concert pieces (Ride of the Valkyries, Magic Fire...). Those are usually slightly different from the parts played in the opera itself and would make it easier to distinguish between opera recordings/classical compilations. Any thoughts?
