Re: adding one ontology to another under a class

Thanks Ian and Olivier,   When I said it did not work, I meant the sub-ontology was not added to the main ontology under the class I wanted.   What I have now is:      OntModelSpec oms = new OntModelSpec(OntModelSpec.OWL_MEM);    oms.setDocumentManager(OntDocumentManager.getInstance());    OntMode

OK - I fixed a minor bug, and retested. It seems the addProperty() method doesn't parse the "4" into an integer form, and this was causing a problem. I'm still seeing the other behavior, but not in this particular case. I'll repost with a better example. -Original Message- From: Joshua

We can't see your ontology and you don't list the results of your test case. However, the Jena rule reasoners are (fragments of) OWL full, not OWL DL. In OWL full then semantically you can state that two literals are sameas, you just can't directly express it syntactically in RDF. The reasoner

That's an awesome way to have a fault tolerant solution. A completely different way of thinking about the problem; my background is more from replicating services so I tend to go for a front-end load balancer with failure detection and two active nodes. It so much depends on exactly what prob

I think I would create a third .owl file that: 1: imports both the "upper" ontology and the "subtree" ontology, 2: lists the subClassOf to bind both ontologies together. This is an easy task if the "subtree" ontology has a small set of identified top-level classes. You can do something similar pr
