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.
