Parsing rdf file containing cardinality restriction

[duy-tran]

I made a new issue since #3 is closed. When parsing an RDF graph containing cardinality, for example:

<owl:Class rdf:about="http://protege.stanford.edu/plugins/owl/owl-library/koala.owl#Animal">
        <rdfs:subClassOf>
            <owl:Restriction>
                <owl:onProperty rdf:resource="http://protege.stanford.edu/plugins/owl/owl-library/koala.owl#hasHabitat"/>
                <owl:minCardinality rdf:datatype="http://www.w3.org/2001/XMLSchema#nonNegativeInteger">1</owl:minCardinality>
            </owl:Restriction>
        </rdfs:subClassOf>
    </owl:Class>

The tag <owl:Restriction> is treated as blank node, raising error java.lang.ClassCastException: Cannot cast a BlankNode to a URI
