Hi Nicola,
yes, you could query for such - just express these as SPARQL queries
for instance, a query against wordnet to get all the subclasses of a
Restriction (wordn-sc:word some wordn-sc:Word) may look like:
PREFIX wordn-sc: <http://www.w3.org/2006/03/wn/wn20/schema/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX owl: <http://www.w3.org/2002/07/owl#>
select * where {
?sub rdfs:subClassOf ?c .
?c a owl:Restriction;
owl:onProperty wordn-sc:word;
owl:someValuesFrom wordn-sc:Word .
}
About the supported inference and its limitations, best is to read
"supported semantics" from the OWLIM Primer document
<http://owlim.ontotext.com/display/OWLIMv50/Primer+Introduction+to+OWLIM#PrimerIntroductiontoOWLIM-SupportedSemantics>

Hi all,
I have another question for you :-)
Considering that OWLIM supports the OWL2 QL and RL profiles, what kinds
of TBox queries can be performed? Are queries with anonymous classes
like "find the subclasses/superclasses/equivalent classes of (R some C)"
possible (with R being a property and C a concept)? Also, are there any
limitations or additions to the "standard" profiles?
Thank you for the very good work with OWLIM, I'm appreciating it more
and more!
Nicola
