Hans, yes it is possible, but I think that your first example was, syntactically, wrong. As far as I can see, it should be: <owl:intersectionOf rdf:parseType="Collection"> <owl:Class rdf:about="#ParticipatingRoleAndDomain"/> <owl:Class> <owl:unionOf rdf:parseType="Collection"> <owl:Class rdf:about="#ClassOfArrangedIndividual"/> <owl:Class rdf:about="#ClassOfEvent"/> <owl:Class rdf:about="#ClassOfPeriodInTime"/> <owl:Class rdf:about="#IndividualDimension"/> <owl:Class rdf:about="#Property"/> <owl:Class rdf:about="#Status"/> </owl:unionOf> </owl:Class> </owl:intersectionOf> The collection should refer to a sequence of classes, whereas owl:unionOf is not a class but owl:property. So you have to define a class that is defined to be the union, and that class can be part of the outermost collection.
