hello all
 
As per your suggestion i have used 
http://protegewiki.stanford.edu/wiki/CompileProtege4InEclipseFromSvn 
 to link protege with eclipse. now i want to know how can i write jena rules and sparql queries for my imported protege files (RDF, OWL) with eclipse.Please give your suggestion as early as possible
 
thank you

The conversion between frames and OWL doesn't work well.

This is an awkward requirement.   But you should investigate the 
possibility that your frame based plugins will simply work in Protege 3 
OWL.  The Protege 3 OWL api is based on the Protege frames api.  So 
depending on the plugins you might be able to get them to work in 
Protege 3 OWL.

For any jena questions I would suggest the mailing list at 
jena.sourceforge.net.

Your example looked a bit complicated so I simplified it to see if I 
understand your issue.  I made a small ontology (attached that includes 
the following abox assertions:

Individual: x
     Types:
         A
     Facts:
      p  y,
      p  z
  
Individual: y
     Types:
         B
     Facts:
      q  1
     
Individual: z
     Types:
         B
     Facts:
      q  2
   

I then ran the following sparql query

PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX : <http://protege.org/ontologies/TwoVariables#>
SELECT ?a ?b ?c
    WHERE {
      ?a :p ?b.
      ?b :q "1"^^xsd:integer.
      ?a :p ?c.
      ?c :q "2"^^xsd:integer.
}


and got one resulting row consisting of "x, y, z".  This seems to be 
what you are looking for?
