Classes in com.hp.hpl.jena.reasoner.rdfsReasoner1 used by com.hp.hpl.jena.reasoner.rdfsReasoner1

BaseFRule
Base class for forward rules.

BRWRule
Datastructure to hold a trivial backward rewrite rule.

RDFSInfGraph
An RDFS reasoner that has been bound to both a TBox and an ABox.

RDFSReasoner
Deprecated. Obsoleted at jena2p4, replaced by RDFSRuleReasoner. An RDFS reasoner suited to modest vocabularies but large instance data. It does eager processing on the class and property declarations and caches the results. This means that the initial creation can be slow. However, if the vocabulary and instance data can be separated then at least the class lattice results can be reused.

Instance related rules are implemented using a very simple rewrite system. Triple queries that match a rule are rewritten and reapplied as queries. This is reasonably efficient for fairly ground queries, especially where the predicate is ground. It performs redundant passes over the data for unground queries, especially any that need that might match (*, type, Resource) or (*, type, Property)!
