Add Annotation to the ObjectPropertyRange

[JProphet89]

Anyone knows who to add a simple annotation to a ObjectPropertyRange like the example bellow?

[sesuncedu]

[Data factory has a range axiom builder method that takes a set of Annotations](http://owlapi.sourceforge.net/javadoc/org/semanticweb/owlapi/model/OWLDataFactory.html#getOWLObjectPropertyRangeAxiom%28org.semanticweb.owlapi.model.OWLObjectPropertyExpression, org.semanticweb.owlapi.model.OWLClassExpression, java.util.Set%29).

OWLDataFactory::getOWLObjectPropertyRangeAxiom if the markdown ate that link.

To give a complete code snippet:

OWLDataFactory df = ...
OWLAnnotationProperty  p=df.getOWLAnnotationProperty(IRI.create("urn:test#backwardCompatibleWith"));
OWLAnnotation ann=df.getOWLAnnotation(p, IRI.create("urn:test#languageDesign"));
OWLObjectProperty op=df.getOWLObjectProperty(IRI.create("urn:test#produces"));
OWLClass c = df.getOWLClass(IRI.create("urn:test#ProgramLanguage"));
OWLObjectPropertyRangeAxiom axiom=df.getOWLObjectPropertyRangeAxiom(op, c, Collections.singleton(ann));

At this point, add the axiom to your ontology and save in the preferred format. From the example, I'm guessing that's OWL/XML.

Given the number of questions I see about how to add annotations, a few more examples should be added to the documentation.

this resolve my problem i finally got it

OWLAnnotationValue val=domain.getIRI();
OWLAnnotation annotation = df.getOWLAnnotation(df.getOWLBackwardCompatibleWith(),val);
OWLObjectPropertyRangeAxiom owlObjectPropertyRangeAxiom=df.getOWLObjectPropertyRangeAxiom(objectProperty, range,new HashSet(Arrays.asList(annotation)));

[ignazio1977]

Note that

new HashSet(Arrays.asList(annotation))

is equivalent to

Collections.singleton(annotation)

Note that you can also get an annotated copy of an existing axiom. There's

OWLAxiom getAnnotatedAxiom(Set<OWLAnnotation> annotations);

Note that this returns a copy of the axioms that the method is called on.
