Agreed that this does help keep it a lot simpler. I guess it depends on
deciding how far schema.org should go in being able to express granularity.
And let me be clear, I don't mind if it's decided that 'artform' is
sufficient enough for this and that further specification isn't
wanted/needed. As long as this is a clear decision.

If it's not too much to ask, could you please provide an example that shows
how one can go about and map this to something like CDWA, VRA CORE, etc?
I'd love to know how you'd go about this and maybe it also could be of
value as an example on schema.org itself.
