Disambiguation for Artist relationships?

[chaban]

Something like this?

Credited as for opera / theatre

Audio dramas would heavily benefit from a proper method too: Another problem is the lack localisation in vocal attribute credits: If I were to enter character names in e.g. Japanese people who can’t read Japanese are going to be unhappy and if I were to enter transliterated names those who do know Japanese will be upset. Maybe N-point relationships are the solution? Personally I like the “roles” idea by nikki.
