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.
