Reading OWL File by using OWLJessKB

 

Hi all

 

Am very new with OWL,Jena, OWLJessKB and Jess. So it may seem that my
questions are very simple to you but please kindly reply me because it
will help me alot for my final year project.

 

I want to read information from OWL file. For example, the file is from
this URL
http://www.atl.lmco.com/projects/ontology/ontologies/animals/animalsA

..owl

 

My first module is to do the following task:

-Find the list of classes in OWL file.

-Find the list of properties for each class.

-Check the characteristics for each property: Eg:

InverfunctionalProperty,Range,Cardinality vv...

 

Currently am trying to use OWLJessKB.Am trying to follow the procedure
in OWL-S Matcher Software from this link

 

http://kbs.cs.tu <http://kbs.cs.tu/> -

berlin.de/ivs/Projekte/owlsmatcher/xref/de/tuberlin/ivs/owl/matching/

Reasoner.html

 

One sample query for InverfuntionalProperty like this:

 

kb.executeCommand( "(defquery query-subproperty (declare (variables ?

y)) (triple(predicate \"http://www.w3.org/2000/01/rdf-
schema#subPropertyOf\")(subject ?x)(object ?y)))" );

 

I trying to run this query but it is not working

 

Does anyone know how to solve this problem or does anyone know another
way to do my project that is easier.

 

I would appriate your help so much

 

Thanks
