Yes. A CreativeWork could be a general notion, such as "The Lord of The
Rings" that Tolkien wrote, or it could be the notion of a specific variant
or edition (hardcover, audiobook, ebook etc.). While the possible notions
are innumerable (including instances in time), there is practical utility
in describing something general and then linking specific examples to that
– both to avoid descriptive repetition and to enable discovery and various
levels of browsing (very much like Product - model -> ProductModel).

(In the library world we work on making catalog systems use these notions
more directly, to facilitate cataloguing and discovery. As you might guess
though, there is plenty of theory to go around. In the context of schema.org,
we are mostly interested in finding a core, basic notion which is
accessible and useful for many kinds of data publishers.)

Yes. 'isBasedOn' reasonably covers general notions of derivative works,
including translations, parodies, adaptations (movies) and so on.

(For anyone interested in the details of at least my point of view here, in
July we discussed relationships between these notions and existing Dublin
Core properties in the SchemaBibEx group – see [1]. I think an important
part of that is about the difference between abstraction and
generalization, for which I used a reference to [2].)
