Prepare yourself to be surprised, Richard, by (re)-reading http://www.w3.org/TR/owl-ref/#Header * Annotation properties must not be used in property axioms. Thus, in OWL DL one cannot define subproperties or domain/range constraints for annotation properties. > > (FWIW, foaf:name is a subproperty of rdfs:label.)
