I don't think seeAlso *is* a property; if it > is, what's in its property extension?? Actually, it is rdfs:name that is not a property. Instead rdfs:label is a property. (I changed from name to label above.) > I wasn't aware of that subproperty connection: is there a source for that? Section 2.3.5 of RDFSS (2000 version). Also in the new RDFS document. By the way, explicit domains and ranges are given for most RDFS properties in the new RDFS document, even when they are rdfs:Resource. The only exceptions are the ranges of rdf:object, rdfs:member, and rdf:value. (I don't recall seeing rdf:value in the RDF MT.) peter
