Thank you Dave, I have a class "Expert", which have sub classes Researcher
and Teacher.
I have Jena rule like: If an Expert ResearchPapers more than 10, assign the
individual to Researcher sub class otherwise to Teacher subclass.
After writing the appropriate Jena rule, apart from SPARQL query
Select * Where{ ?ind rdf:type ont:Researcher . ?ind rdf:type ont:Teacher}
What is the alternate way to parse/execute the rule and the result
transfers to our infmodel. ?
