URI of anonymous classes
Hi there
I am rewriting an ontology using jena. I rewrite each import. When rewriting an importing ontology, anonymous classes (e.g. restrictions or disjointness axioms) of the imported ontology appear twice in the importing ontology, because to re-write the importing ontology I am working with OntModelSpec.OWL_DL_MEM, to make sure rewrite instances asserted in the importing ontology of classes declared in the imported ontology.
Question: is there a way of telling in jena where (at which URI) was a restriction or an axiom asserted?
Note: Protege has a tooltip saying "Asserted in: URI" of such classes. But the rdf/xml file does not seem to have such a property.
Subquestion: Does protege compute this property by looking at all URI of all statements oft he anonymous classes?
Hope I am making sense. Jos

Models in Jena contain the statements, thus, you should be able to
determine which model contains the statement.

Jos, this reminds me of a similar issue I had:
https://www.mail-archive.com/users@jena.apache.org/msg06279.html
Ideally you should have explicit rdfs:isDefinedBy statements for each term,
linking them to their defining ontology.

AW: AW: URI of anonymous classes
Posted by Jos Lehmann <Jo...@bauhaus-luftfahrt.net>.
Hi Lorenz
If you could be more specific it would help.
The restrictions I am working with don't seem to have a URI, so I can't tell if, in the input ontologies, they belong to the imported ontology or to the importing ontology. I.e.:
WHEN DOING:
ExtendedIterator properties = thisClass.listProperties();
while (properties.hasNext()) {
Statement thisProperty = (Statement) properties.next();
if (!(((Character.isDigit(thisProperty.getObject().toString().charAt(0)))) || thisProperty.getObject().toString().startsWith("-"))) {
newClass.addProperty(thisProperty.getPredicate(), thisProperty.getObject());
}
else
{System.out.println("Anonymous class: " + thisProperty.getObject().toString());
System.out.println("Anonymous class' URI: " + ((Resource) thisProperty.getObject()).getURI());
I GET, FOR INSTANCE:
Anonymous class: 1a26f878:161d895229e:-7e84
Anonymous class' URI: null
How else can I programmatically determine whether a restriction comes from the imported or from the importing ontology
Cheers, Jos

You can get access to imported models via
OntModel::getImportedModel(String uri)
or
OntModel::listSubModels(boolean withImports)
Javadoc[1] is always your friend.

Re: AW: URI of anonymous classes

You can get access to imported models via
OntModel::getImportedModel(String uri)
or
OntModel::listSubModels(boolean withImports)
Javadoc[1] is always your friend.

When rewriting an importing ontology, anonymous classes (e.g. restrictions or disjointness axioms) of the imported ontology appear twice in the importing ontology, because to re-write the importing ontology I am working with OntModelSpec.OWL_DL_MEM, to make sure rewrite instances asserted in the importing ontology of classes declared in the imported ontology.

AW: URI of anonymous classes
Posted by Jos Lehmann <Jo...@bauhaus-luftfahrt.net>.
As an integration to my question (see Ursprüngliche Nachricht) please see further down the ouput of re-writing the importing ontology*.
The same intersection is repeated. Yet, Protege is able to tell that one of the two intesections comes from the imported ontology the other from the importing ontology. How? How to tell the the same thing in jena.

Betreff: URI of anonymous classes
Hi there
I am rewriting an ontology using jena. I rewrite each import. When rewriting an importing ontology, anonymous classes (e.g. restrictions or disjointness axioms) of the imported ontology appear twice in the importing ontology, because to re-write the importing ontology I am working with OntModelSpec.OWL_DL_MEM, to make sure rewrite instances asserted in the importing ontology of classes declared in the imported ontology.
Question: is there a way of telling in jena where (at which URI) was a restriction or an axiom asserted?
Note: Protege has a tooltip saying "Asserted in: URI" of such classes. But the rdf/xml file does not seem to have such a property.
Subquestion: Does protege compute this property by looking at all URI of all statements oft he anonymous classes?
Hope I am making sense. Jos
