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.) FOAF is RDFS, not OWL-DL Bernard -- *Bernard Vatant *Knowledge Engineering ---------------------------------------------------- *Mondeca** *3, cité Nollez 75018 Paris France Web: www.mondeca.com <http://www.mondeca.com> ---------------------------------------------------- Tel: +33 (0) 971 488 459 Mail: bernard.vatant@mondeca.com <mailto:bernard.vatant@mondeca.com> Blog: Leçons de Choses <http://mondeca.wordpress.com/>
