I hope that this is the right place to report this. In the OWL 2 primer [1] there is an rdf version of the sample ontology. You can find it by going to [2], disabling all the syntaxes except rdf and then going to [3]. I have attached a copy for reference. It looks like it has a couple of syntax errors (the owl api doesn't like this ontology). First the Orphan class has a definition as follows: <owl:Class rdf:about="Orphan"> <owl:equivalentClass> <owl:Restriction> <owl:onProperty> <owl:ObjectProperty> <owl:inverseOf rdf:resource="hasChild"/> </owl:ObjectProperty> </owl:onProperty> <owl:Class rdf:resource="Dead"/> <----- this should be owl:someValuesFrom? </owl:Restriction> </owl:equivalentClass> </owl:Class> I think that the inner owl:Class should be owl:someValuesFrom. Second the Teenager class <owl:Class rdf:about="Teenager"> <rdfs:subClassOf> <owl:Restriction> <owl:onProperty rdf:resource="hasAge"/> <owl:someValuesFrom> <rdfs:Datatype> <owl:onDataType rdf:resource="&xsd;integer"/> <-------- should be owl:onDatatype? <owl:withRestrictions rdf:parseType="Collection"> <rdf:Description> <xsd:minExclusive rdf:datatype="&xsd;integer">12</xsd:minExclusive> </rdf:Description> <rdf:Description> <xsd:maxInclusive rdf:datatype="&xsd;integer">19</xsd:maxInclusive> </rdf:Description> </owl:withRestrictions> </rdfs:Datatype> </owl:someValuesFrom> </owl:Restriction> </rdfs:subClassOf> </owl:Class> I think that the second "t" in owl:onDataType should not be capitalized. Also the import seems to fail which is more annoying (it takes a long time to fail) than a real problem. -Timothy [1]http://www.w3.org/TR/owl2-primer/ [2]http://www.w3.org/TR/owl2-primer/#OWL_Syntaxes <http://www.w3.org/TR/owl-primer/#OWL_Syntaxes> [3]http://www.w3.org/TR/owl2-primer/#Appendix:_The_Complete_Sample_Ontology
