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'.
