Big problem with InfModel

Hello folks,

I have a nasty problem with having some InfModel as a base for another 
new model.

I do it the following way:
OntModel x = ModelFactory.createOntologyModel(OntModelSpec.OWL_DL_MEM, 
infModel)

Now when adding some properties to x, it seems, that this properties are 
added to infModel as well, which I don't want. I want to have an 
ontology based on an infModel, not a composition of both.

What I try to have, is the following:

OntModel x = ModelFactory.createOntologyModel(OntModelSpec.OWL_DL_MEM, 
infModel.clone())

But I'm not able to do that cloning of infModel :-(

Any fast help would be great.

Thanks for your great support!!!

Bye Dennis

So that's passing infModel as the base model to the OntModel, and it is 
indeed the base model that receives updates.

What I suspect you want is:

OntModel x = ModelFactory.createOntologyModel(OntModelSpec.OWL_DL_MEM );
x.addSubModel( infModel );
