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.
