Overview
The Expansion module performs a subset of OWL entailment rules on the base class, which implementes RDF::Readable.
Defined Under Namespace
Classes: Rule
Instance Method Summary collapse
-
#copy_properties(repository) ⇒ Object
Perform property copying on the resulting default graph.
-
#expand(repository) ⇒ Object
Perform vocabulary expansion on the resulting default graph.

Instance Method Details
#copy_properties(repository) ⇒ Object
Perform property copying on the resulting default graph.
For all objects of type rdfa:Pattern that are the target of an rdfa:copy property, load the IRI into a repository.
Subsequently, remove reference rdfa:Pattern objects.

#expand(repository) ⇒ Object
Perform vocabulary expansion on the resulting default graph.
Vocabulary expansion uses the built-in reasoner using included vocabularies from RDF.rb.
