Josh & Leigh, thanks for bringing up the license issue...My comments
are specific to that, so I've cropped the thread and inserted comments
below...

I think we should/could follow the DCAT model here, which uses
dc:license to refer to a dc:LicenseDocument

I think CreativeWork is intended to be high level, to be extended by a
rich and growing set of specific types (including Datasets). One might
argue that the notion of "license" doesn't apply to all such
specializations of creative work, and each specialization should add
rights vocabulary that suits them best.

That said, CopyrightHolder *does* appear at the CreativeWork level;
RightsHolder would have been better...

I "vote" for a simple solution in the spirit of dc:license and not for
constrained lists. If someone wants to create a "License" extension or
even a "Legal" extension that introduces legalese into the mix, that's
fine, but Datasets or other CreativeWork-based extensions shouldn't
depend on it...
