Hi Karen

+1 for this.

Of interest also is how "subjects" are or will be included in the RDF
In your example of "Edition" the subject value is a blank node representing
a DDC classification in DC namespace.
It's OK although direct URIs for DDC entities would be simpler (things we
could consider in the use case)

OTOH at http://openlibrary.org/subjects/halley's_comet I don't see any
indication of an RDF description, but in records such as
http://openlibrary.org/works/OL141696W.rdf the subject "Halley's comet" is
plain text value of dc:subject.

Those examples point at central issues re. names vs URIs vs identifiers and
definitely it seems a good use case I would gladly work on.
