It's ok.  Vice versa is not.

I think it'd be ok, so long as Carla's attribution and notice of the
Attribution license is preserved -- assuming the GFDL isn't incompatible
with such requirements.

Regarding my comments above, IANAL, etc.

Yep, it's on our TODO list.

Yes, and it corresponds with two things I intend to do:

* License RDF info/validation service: enter a URL, service tells you
what RDF available at URL says.

* Adding source work to suggested optional work metadata, which I believe
would appear in the RDF as dc:source.  

Thanks for your comments!

Mike

p.s. I'll let someone else answer your "or any later version" question.
