How to create annotations of annotations

Original Subject: How to create (or copy) annotations of annotations (i.e. axioms) (from a model) to a(nother) model in jena?


Hi there

SITUATION

1. I have an ontology with individuals that have (i) Annotations as well as (ii) Annotations of Annotations.

2. In RDF/XML, (ii) above are expressed as Axioms as in Example#1 below.

3. I manage to extract (ii) from the my RDF ontology using Code#1 below and I get Output#1

PROBLEM

4. I have managed to copy the individuals and their annotations ((i) above) but fail to copy the annotations of annotations ((ii)) to the second model. I have unsuccessfully tried by adding to Code#1 (see upper-case comment) something like:

model2.createResource(thisPropertyOfThisInstanceProperty);



Please let me know if you need more info or you can think of doing this.

Thank you in advance for the advice.

Example#1 (RDF/XML Input)

<owl:Axiom>
<owl:annotatedSource rdf:resource="http://www.XXX.net/ontologies/2016/Ls_Ontology.owl#ATR"/>
<owl:annotatedProperty rdf:resource="http://www. XXX.net/ontologies/2016/PS_Ontology.owl#Alias_English_Alias_9"/>
<owl:annotatedTarget xml:lang="en">Whyatr.com</owl:annotatedTarget>
<ps:Disambiguation_English_Word_1 xml:lang="en">airplane</ps:Disambiguation_English_Word_1>
<ps:Disambiguation_English_Word_2 xml:lang="en">airframer</ps:Disambiguation_English_Word_2>
</owl:Axiom>

END-- Example#1



Code#1 (adapted from https://www.google.de/#q=jena+how+to+create+an+axiom+from+a+model+to+another+an+axiom)

ExtendedIterator propertiesOfThisInstanceProperty = model.listSubjectsWithProperty(RDF.type, OWL2.Axiom);
//
while (propertiesOfThisInstanceProperty.hasNext()) {

Resource thisPropertyOfThisInstanceProperty = (Resource) propertiesOfThisInstanceProperty.next();
System.out.println("Found axiom: " + thisPropertyOfThisInstanceProperty.toString());
ExtendedIterator test = thisPropertyOfThisInstanceProperty.listProperties();
// FAILED ADDITION OF CODE IN 4. ABOVE
while (test.hasNext()) {
//
Statement thisPropertyOfNewInstanceProperty = (Statement) test.next();
System.out.println(" Found axiom-related stuff: " + thisPropertyOfNewInstanceProperty.toString());

}


}
END-- Code#1



Output#1
