That is not correct. The statement <rdfs:subPropertyOf rdf:resource="http://purl.org/dc/elements/1.1/contributor"/> is a single predicate-object statement, enclosed within angle brackets. The following statement <rdf:type rdf:resource="http://www.w3.org/2002/07/owl#ObjectProperty"/> is also separate statement, enclosed within angle brackets. The OWL statement is not part of the subPropertyOf statement. The next statement is also a separate statement. So we have three statements: subPropertyOf: DC contributor type: owl ObjectProperty type: BIBFRAME role The term you were looking up is the implied subject of the statements, making these RDF triples.
