com.hp.hpl.jena.reasoner	The Jena2 reasoner subsystem is designed to allow a range of inference engines to be plugged into Jena.
com.hp.hpl.jena.reasoner.rdfsReasoner1	This package contains an example RDFS reasoner.
com.hp.hpl.jena.reasoner.transitiveReasoner	This package contains a reasoner which supports transitive-reflexive closure of subPropertyOf and subClassOf relations.
