If I can make decisions in OWL based on what might happen to RDF in the future, I have a lot of other changes that I would like to make. :-) > So I don't see any reason why owl:SymmetricProperty should > be constrained to be a subclass of owl:ObjectProperty. Well any owl:SymmetricProperty in OWL DL would, of necessity, have an empty extension, so would not be very useful. In OWL Full, there is no need for the division of properties into individual-valued and data-valued. In OWL Full, stating that property is an owl:ObjectProperty doesn't place any restrictions on the property, so there is no problem here either.. peter
