Jena で修飾カーディナリティ制限を追加するにはどうすればよいですか? はOWL2ではなく、OWLの最初のバージョン用なcreateCardinalityQRestrictionので使えません。OntModelSpecModelFactory の createOntologyModel で、OWL2 オントロジーを作成する方法はありますか? 次のようなクラス式が必要です

私はこのコードを使用してみました：

OntModel ontModel = ModelFactory.createOntologyModel();
OntClass ret = ontModel.createCardinalityQRestriction(null, ontProperty, cardinality,    ontClass2 );
ontClass.addSuperClass(ret);

しかし、私はこの例外を受け取ります:

com.hp.hpl.jena.ontology.ProfileException: 現在の言語プロファイルでサポートされていない言語構造 CARDINALITY_Q を使用しようとしました: OWL Full

    private void createOneToMany(OntModel ontoModel, OntClass ontoClass, OntProperty prop, Resource resource) {
        OntClass allValuesFromRestriction = ontoModel.createAllValuesFromRestriction(null, prop, resource);
        ontoClass.addSuperClass(allValuesFromRestriction);

        OntClass minCardinalityRestriction = ontoModel.createMinCardinalityRestriction(null, prop, 1);
        ontoClass.addSuperClass(minCardinalityRestriction);
    }

    private void createZeroToMany(OntModel ontoModel, OntClass ontoClass, OntProperty prop, Resource resource) {
        OntClass allValuesFromRestriction = ontoModel.createAllValuesFromRestriction(null, prop, resource);
        ontoClass.addSuperClass(allValuesFromRestriction);

        OntClass minCardinalityRestriction = ontoModel.createMinCardinalityRestriction(null, prop, 0);
        ontoClass.addSuperClass(minCardinalityRestriction);
    }

    private void createZeroToOne(OntModel ontoModel, OntClass ontoClass1, OntProperty prop, OntClass ontoClass2) {

        OntClass minCardinalityRestriction = ontoModel.createMinCardinalityRestriction(null, prop, 0);
        ontoClass1.addSuperClass(minCardinalityRestriction);

        OntClass maxCardinalityRestriction = ontoModel.createMaxCardinalityRestriction(null, prop, 1);
        ontoClass1.addSuperClass(maxCardinalityRestriction);
    }

    private void createOneToOne(OntModel ontoModel, OntClass ontoClass1, OntProperty prop, OntClass ontoClass2) {
        OntClass minCardinalityRestriction = ontoModel.createMinCardinalityRestriction(null, prop, 1);
        ontoClass1.addSuperClass(minCardinalityRestriction);

        OntClass maxCardinalityRestriction = ontoModel.createMaxCardinalityRestriction(null, prop, 1);
        ontoClass1.addSuperClass(maxCardinalityRestriction);
    }

次に、次のことができます。

OntModel ontModel = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM);
OntClass task = ontModel.createClass(OWL.NS + "Task");
OntClass actor = ontModel.createClass(OWL.NS + "Actor");
OntProperty propTask = ontModel.createObjectProperty( OWL.NS + "Task-performedBy-Actor");
OntProperty propActor = ontModel.createObjectProperty( OWL.NS + "Actor-performs-Task");

呼び出すには:

   createOneToMany(ontModel, task, prop, actor);
   createZeroToMany(ontModel, task, prop, actor);
   createOneToOne(ontModel, task, propTask, actor);
   createZeroToOne(ontModel, actor, propActor, task);
