Hi Dave,
thanks for your reply. I've already tried OWL_MICRO, but it does not
work for transitive properties (ontModel.createTransitiveProperty()) -
or do I have to configure something in addition to make it work?

Hi,
I've got an OntModel with OnModelSpec.OWL_MEM_RULE_INF set that
contains
about 25.000 statements and only 1(!) transitive property. Now I'm
trying to list all Statements with a special subject
(http://myResource)
by calling
StmtIterator iter =
model.listStatements(model.createResource("http://myResource";), null,
(RDFNode) null);
Although execution of this method does not take a long time (some
seconds) I run in serious trouble/performance issue when calling
iter.hasNext();
This call does not terminate within 5 minutes and I'm asking myself if
what's wrong. Therefore I'm looking for better solution and your
suggestions... ;-)
The inference engine is taking a long time, that's all :)
Try with OWL_MICRO or switch to Pellet.

SORRY - my fault. everything is working fine when using OWL_MICRO!
Thanks for your advice,
Thorben
