I am happy to change. Syntactic choices. Alan seems to think that we can just add a valuesFrom triple e.g. <owl:Restriction> <owl:cardinality rdf:datatype="&xsd;int">2</owl:cardinality> <owl:onProperty rdf:resource="⪚hasDigit"/> <owl:fromValues> <owl:Class rdf:about="⪚Thumbs"/> </owl:fromValues> </owl:Restriction> Unfortunately this contains a standard restricition inside it <owl:Restriction> <owl:cardinality rdf:datatype="&xsd;int">2</owl:cardinality> <owl:onProperty rdf:resource="⪚hasDigit"/> </owl:Restriction> and the relationship is non-monotonic. Thus we have to change something ... D+O used cardinalityQ instead of cardinality Pat was suggesting the rather clearer cardinalityFrom The other options are to: change the class from say owl:Restriction to owl:QualifiedRestriction change the onProperty to say owl:qualifiedProperty I believe any of those could be made to work monotonically. (The non-mon worry is only an OWL Full issue). Jeremy
