RDF/RDFS has no inherent semantics that means what you are asking for - that's the job of, i.e., owl - so in that sense, "no". OTOH, you can define any "terms" you like and use them that way. In that sense, "yes". But they won't be standard and so they won't be understood by standard processors. > if not, then perhaps > it is worth considering a non-anoymous resource for this relationship so > that one can still define the architecture of the bibterm:book property > in RDF/RDF-S semantics. > You can give an anonymous node an rdf:type without having to give it an identifying uri. So you can actually have both ways in this case. -- Thomas B. Passin Explorer's Guide to the Semantic Web (Manning Books) http://www.manning.com/catalog/view.php?book=passin
