We have non-music artists in the database, for instance when a poets work is put to music, the poet is entered as an artist. But in that case the focus is still on audio releases, so this widening of the scope is fairly limited. If we would allow any sort of non-music-performer-at-an-event into the database, this could result in millions of performers that have nothing to do with music/audio. I don’t think that’s where we want to go.
At the same time I understand why you would want this. To represent an event properly you would want to show all acts that are programmed. Also, @sanojjonas recently showed us how you could use MB-event-data to generate timetables for festivals. Such use-cases would be far more limited if non-music parts of events can’t be included in any way.
I am wondering if it’d be a good idea to have a special purpose artist for this, so we could input the ‘[placeholder] credited as artist-name’. That way we could truly show all elements of events without making every non-music element itself part of the MB-database.
