[RDF IG folks: note that XML Infoset is in last call, and it includes an RDF schema that, while normative, could be awfully useful. Please review it. I found a few bugs.] My understanding* of rdfs:domain is: If prop(subj, obj) and rdfs:domain(prop, X) then rdf:type(subj, X). By that logic, this is almost certainly not what is meant: ///////// <rdfs:Property ID='baseURI'> <rdfs:domain resource='#Document'/> <rdfs:domain resource='#Element'/> <rdfs:domain resource='#ProcessingInstruction'/> <rdfs:domain resource='#ExternalEntity'/> <rdfs:range resource='http://www.w3.org/2000/01/rdf-schema#Literal'/> </rdfs:Property> \\\\\\\\\\ -- http://www.w3.org/2001/02/infoset# http://www.w3.org/TR/xml-infoset/#rdfschema http://www.w3.org/TR/2001/WD-xml-infoset-20010202/#rdfschema that says that anything with a baseURI property is a Document *and* an Element *and* ... . I think what you mean is that anything with a baseURI property is a Document *or* and Element *or* ...; i.e. the domain is a superclass of all those (and a subclass of InfosetItem). I plan to follow up with specific replacement wording/code. * there's some wording in the spec that suggests otherwise, but I think it's bogus and lots of other folks do too; cf "Semantics of Domain and Range constraints http://lists.w3.org/Archives/Public/www-rdf-interest/2000Jun/0018.html http://lists.w3.org/Archives/Public/www-rdf-interest/2000Jul/0032.html http://lists.w3.org/Archives/Public/www-rdf-interest/2000Sep/0132.html " from http://lists.w3.org/Archives/Public/www-rdf-interest/2000Sep/0240.html linked from http://www.w3.org/2000/03/rdf-tracking/ btw... DanBri, I searched for 'domain' in http://www.w3.org/2000/03/rdf-tracking/ and was shocked that it doesn't occur; please do incorporate the "More material to be incorporated". -- Dan Connolly, W3C http://www.w3.org/People/Connolly/
