I haven't met anyone doing that, personally. As far as I've seen, the
major RDF implementations are RPMfind, DMoz, and a couple of others
I'm forgetting right now. No Dublin Core involved in either of them.

Actually, there should be no need to do anything like that. I imagine
a Web of objects (in RDF/DC or otherwise) would look something like
this:
<megg:Person rdf:about="http://megginson.com/objects/12345">
<dc:title>David Bowie</dc:title>
<dc:date>1947-01-08/</dc:date>
</megg:Person>
<megg:Song rdf:about="http://megginson.com/objects/54321">
<dc:title>Space Oddity</dc:title>
<dc:date>1972</dc:date>
<dc:creator rdf:resource="http://megginson.com/objects/12345"/>
</megg:Song>
A composer is just the creator of a song, while a sculptor is the
creator of a sculpture. There's no need to define all of the things
dc:creator can refer to, as long as you explain the kind of
relationship it defines.
All the best,
David
