Class OWLMiniReasoner

java.lang.Object
  com.hp.hpl.jena.reasoner.rulesys.FBRuleReasoner
      com.hp.hpl.jena.reasoner.rulesys.GenericRuleReasoner
          com.hp.hpl.jena.reasoner.rulesys.OWLMiniReasoner

All Implemented Interfaces:

Reasoner, RuleReasoner

public class OWLMiniReasoner
extends GenericRuleReasoner
implements Reasoner

Reasoner configuration for the OWL mini reasoner. Key limitations over the normal OWL configuration are:

• omits the someValuesFrom => bNode entailments
• avoids any guard clauses which would break the find() contract
• omits inheritance of range implications for XSD datatype ranges

Constructor

Method Detail

loadRules

public static List<Rule> loadRules()

Return the rule set, loading it in if necessary

bind

public InfGraph bind(Graph data)
              throws ReasonerException

Attach the reasoner to a set of RDF data to process. The reasoner may already have been bound to specific rules or ontology axioms (encoded in RDF) through earlier bindRuleset calls.

Specified by:

bind in interface Reasoner

Overrides:

bind in class GenericRuleReasoner

Parameters:

data - the RDF data to be processed, some reasoners may restrict the range of RDF which is legal here (e.g. syntactic restrictions in OWL).

Returns:

an inference graph through which the data+reasoner can be queried.

Throws:

ReasonerException - if the data is ill-formed according to the constraints imposed by this reasoner.

getGraphCapabilities

public Capabilities getGraphCapabilities()

Return the Jena Graph Capabilties that the inference graphs generated by this reasoner are expected to conform to.

Specified by:

getGraphCapabilities in interface Reasoner

Overrides:

getGraphCapabilities in class FBRuleReasoner
