我有一個.owl文件是這樣的:OWLAPI:獲取IRI在AnnotationAssertion
...
<ClassAssertion>
<Class IRI="http://timbus.teco.edu/ontologies/DIO.owl#BusinessProcess"/>
<NamedIndividual IRI="#bf1badca"/>
</ClassAssertion>
...
<AnnotationAssertion>
<AnnotationProperty abbreviatedIRI="rdfs:label"/>
<IRI>#bf1badca</IRI>
<Literal datatypeIRI="http://www.w3.org/2001/XMLSchema#string">Remove_old_books</Literal>
</AnnotationAssertion>
我想獲得,是針對在聲明中指定的個人IRI類名(BusinessProcess)註釋斷言(#bf1badca)
我有下面的代碼可以訪問在註釋文字的值:
OWLOntologyWalker walker = new OWLOntologyWalker(Collections.singleton(ontology));
OWLOntologyWalkerVisitor visitor = new OWLOntologyWalkerVisitor(walker) {
@Override
public void visit(OWLAnnotationAssertionAxiom axiom) {
OWLLiteral val = (OWLLiteral)axiom.getValue();
System.out.println(val.getLiteral());
// Prints 'Remove_old_books'
}
};
如何訪問註釋斷言的IRI領域,我.e,值#bf1badca?
非常感謝! – luispcosta
