QDC basically represents the same things has dcterms, so you can
probably just take the existing XSLT and hack on it until it until it
represents something that looks more like dcterms than qdc.

That won't address of the issue of breaking up the MARC into
individual resources, however.  You mention that you are looking for
the short hop to RDF, but this is just going to give you a big pile of
literals for things like creator/contributor/subject, etc.  I'm not
really sure what the "win" would be, there.
