/**
 * Refers to http://www.w3.org/TR/rdf-schema/#ch_statement
 * rdf:Statement is an instance of rdfs:Class. It is intended to represent the class of RDF statements.
 * An RDF statement is the statement made by a token of an RDF triple. The subject of an RDF statement is the instance
 * of rdfs:Resource identified by the subject of the triple. The predicate of an RDF statement is the instance of
 * rdf:Property identified by the predicate of the triple. The object of an RDF statement is the instance of
 * rdfs:Resource identified by the object of the triple. rdf:Statement is in the domain of the properties rdf:predicate,
 * rdf:subject and rdf:object. Different individual rdf:Statement instances may have the same values for their
 * rdf:predicate, rdf:subject and rdf:object properties.
