This sounds like it's drifting towards an isRelatedTo property where the
nature of the relationship is undefined.  Creative works can be
automatically clustered in all kinds of ways, but the engines that do that
type of work won't be wanting to express the results in
schema.orgvocabularies, in my opinion.

Yes, I favor specific properties and I don't think there are that many of
them to cover the popular relationships that we describe in prose.
 Adaptation, translation, work/edition, and subject cover the vast majority
of the common cases.  I think commonEndeavor should be deleted.

I'll try to find some time to work through Chaals' examples, but in the
mean time it might be instructive to browse the various topics here:

  https://www.freebase.com/search?query=Romeo+and+Juliet

and see how they are connected together.  Obviously the Freebase schema is
more detailed than is appropriate for schema.org, but I think a lot of the
basics apply.  In particular, they've gotten a huge amount of mileage out
of an adaptionOf property applied to all different types of media.

The biggest point for me is that it the properties don't match the (human)
vocabulary that we use to talk about this stuff, it will be harder to
understand and less likely to be used.  If you look at West Side
Story<https://www.freebase.com/m/085xh> is
has a specific relationship to Shakespeare's Romeo & Juliet, its own film
adaptations, DVDs of films, sound tracks, etc.  If you read the Wikipedia
articles, you'll see a very common vocabulary used to describe all these
relationships.
