NAME

RDF::Closure::Engine - an engine for inferring triples

DESCRIPTION

Constructor

• new($regime, $model, @arguments)

  Instantiates an inference engine. This:

  RDF::Closure::Engine->new('RDFS', $model, @args);

  is just a shortcut for:

  RDF::Closure::Engine::RDFS->new($model, @args);

  Though in the former, 'RDFS' is treated case-insensitively.

  $model must be an RDF::Trine::Model which the engine will read its input from and write its output to.

Methods

• entailment_regime

  Returns a URI string identifying the type of inference implemented by the engine, or undef.

• graph

  Returns the RDF::Trine::Model the engine is operating on.

• closure( [ $is_subsequent ] )

  Adds any new triples to the graph that can be inferred.

  If $is_subsequent is true, then skips axioms.

• errors

  Returns a list of consistency violations found so far.

• reset

  Removes all inferred triples from the graph.

Class Method

• engines

  Return a list of engines installed, e.g. 'RDF::Closure::Engine::RDFS'.
