Hi Martynas,
So you could use something like:
ontmodel.listStatements(null, GP.uriTemplate , (RDFNode)null)
to list all the classes with templates in your union ont model. Then use:
ontmodel.isInBaseModel( statement )
to check whether the resulting statement came from the base model.
If that's not flexible enough you can always use getBaseModel() to get
the base model with no imports and do full API/SPARQL queries over that
separate from the union model.

Dave,
I have something like this:
==== A.owl ====
<#A> a owl:Ontology ;
owl:imports <#B>, <#C> .
<#RA> a owl:Class ;
gp:uriTemplate "/A" ;
rdfs:isDefinedBy <#A> .
==== B.owl ====
<#B> a owl:Ontology .
<#RB> a owl:Class ;
gp:uriTemplate "/B" ;
rdfs:isDefinedBy <#A> .
==== C.owl ====
<#C> a owl:Ontology .
<#RC> a owl:Class ;
gp:uriTemplate "/C" ;
rdfs:isDefinedBy <#C> .
=============
What I want to do, is to process OntClasses that have gp:uriTemplate
values, but give classes from <#B> and <#C> lower priority since they
are owl:imported. That is, if a URI template matches <#RA>, then <#RB>
and <#RC> need not be processed. Does that sound reasonable?
I called <#A> the "root" ontology because it imports the other two.
But since OntModel is a union of all statements, that is probably
irrelevant.
Alternatively I guess I could check rfds:isDefinedBy to see if
OntClass belongs to <#A> or not.

Hey,
is it possible to check if resource in OntModel comes from the
main/root ontology or the owl:imports?
Is thought that is what isInBaseModel() does, but I don't get expected
result.
http://jena.apache.org/documentation/javadoc/jena/com/hp/hpl/jena/ontology/OntModel.html#isInBaseModel(com.hp.hpl.jena.rdf.model.RDFNode)
Depends what you mean by a resource "coming from" a model.
In Jena models just contain statements, there is no separate notion of a
model containing a resource.
What OntModel#inBaseModel(RDFNode) does is test if there are any statements
involving that RDFNode in the base model. However, typically in ontologies
terms can be used in the base ontology but defined in the imports. If that's
the case you will see statements about it in both the base and the import
models.
You may want to use isInBaseModel(Statement) to, for example, see whether
the type of your resource is defined in the base model.
