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'.
