Hi Aaron,

Perhaps though, the dramatization would be considered as another kind of
creative work? Of course, more to the point, would such a distinction be
important for users in general? (If I look for an audiobook, would I be
surprised by an audio drama?)

This sounds reasonable. The type should determine its specific contextual
meaning readily enough.

I definitely think that an "isBasedOn" property – with a range of
CreativeWork – could be a useful addition! (It would be rather like
dc:source or prov:wasDerivedFrom in meaning).

In the SchemaBibEx group, we've been discussing similar properties
(exampleOfWork, isVersionOf, editionOf etc.) in relation to levels of
abstractions or generalizations as well (for that difference, compare the
FRBR exclusive abstraction levels with the
ProductModel/Product/IndividualProduct levels of specificity). I think
"isBasedOn" could be a valuable start. (Also in relation to the suggested
"adaptationOf", figuring in the accessibility topic recently discussed

Especially since, in comparison, the "isBasedOnUrl" property is very
strange from a linked data perspective (with its range of URL instead of
