我编写了此代码来替换对象属性值：

 public void changeObjectPropertyValue(String ind, String propertyFragment, String newValueFragment) {

        OWLNamedIndividual individualToReplaceValueOn = factory.getOWLNamedIndividual(prefix + ind);
        OWLNamedIndividual newValueInd = factory.getOWLNamedIndividual(prefix + newValueFragment);
        OWLObjectProperty theObjectProperty = factory.getOWLObjectProperty(prefix + propertyFragment);
        OWLIndividual theOldValue = EntitySearcher.getObjectPropertyValues(individualToReplaceValueOn, theObjectProperty, ont).findFirst().get();

        OWLAxiom oldAxiom = factory.getOWLObjectPropertyAssertionAxiom(
                theObjectProperty,
                individualToReplaceValueOn,
                theOldValue);

        OWLAxiom newAxiom = factory.getOWLObjectPropertyAssertionAxiom(
                theObjectProperty,
                individualToReplaceValueOn,
                newValueInd);

        List<OWLOntologyChange> changes = new Vector<OWLOntologyChange>();

        changes.add(new RemoveAxiom(ont, oldAxiom));
        changes.add(new AddAxiom(ont, newAxiom));
        manager.applyChanges(changes);
    }

我想知道这是否是替换值的正确方法，以及 OWLAPI 库中是否有一种方法可以做到这一点？
