[Pellet-users] Minor bug: exception when property contains whitespace

[Thorsten Möller]

Hello,

I just found a minor issue in Pellet 2.0-RC7. When an ontology property 
contains whitespace an exception is thrown, see below.

Seems that the mapping from lexical to value space can take advantage of 
the Jena machinery: Line 479 of DefaultGraphLoader should be something 
like

    int cardinality = ((Integer) 
filler.getLiteral().getValue()).intValue();

rather than

    int cardinality = Integer.parseInt( 
filler.getLiteral().getLexicalForm() );

Are there more such cases?

The following example can be used to reproduce it:

<owl:Class rdf:ID="Parameter">
    <rdfs:subClassOf>
    <owl:Restriction>
    <owl:onProperty rdf:resource="#parameterType" />
    <owl:minCardinality rdf:datatype="&xsd;#nonNegativeInteger">
1</owl:minCardinality><!-- line break whitespace -->
    </owl:Restriction>
</rdfs:subClassOf>


Cheers,
Thorsten
