Might you release the schema into the public domain? I know that's much more easily said than done, and it's your hard work and you deserve the benefits, so no argument from me if you don't.

Or maybe share some tips on what works with the corpus of classical metadata?

While I'd love to see some of the quite spectacular internal tooling + data to be released under an open license, put to use for enhancing MusicBrainz' existing data etc., I doubt it's going to happen.

All team members have started new opportunities since quite a while and untangling all this, filtering out potentially copyrighted/licensed material etc. would take quite some effort.
