But why bother with rdfs:range at all?! Just declare s:age as a subPropertyOf xsd:duration, right, since all data types are defined using properties... Am I the only one to see a conflict here? (though that may not be so surprising ;-) I.e. what is the interpretation of the following knowledge: x s:age "P12Y" . s:age rdfs:range xsd:duration . s:age rdfs:subPropertyOf xsd:duration . According to the S proposal, either range or subproperty relations can define type. Which is it going to be? Both?! Eh? Patrick
