What are the obligatory rdf triples? Apparently editors of collections have no predefined tag and ommit creator. What about books with various authors?

I used to edit in the header to RDF files, but gave up... I think essentially all RDF files are copyrighted, so we leave it to the contributor to insert whatever metadata they desire. My practice these days is to add a README.TXT with the triples & header & license. I don't think anyone but me has posted an RDF file in awhile, but could be wrong... you are correct that they are not standard. -- Greg Dr. Gregory B.
