I have seen people trying to declare range and domain semantics for "all instances of a certain subClassOf rdf:Property" though. In fact, DAML does something like that, as I recall. > which is to declare the range of a property (called > myProperty) to be the set of subclasses of #Animal. Ah, the *set* of subClasses, not a particular set. Well, thanks to DanC coming up with a neat little vocabulary for that and given it a date-stamped W3C URI, I guess the case is closed :-) -- Kindest Regards, Sean B.
