Instance Method Details

#<<(provenance_fact) ⇒ Object

Add a ProvenanceFact (strictly only a ProvenanceFact).

Side effect on subject:

  • if it has no subject, the subject is set in a duplicate provenance_fact
  • if is has the same subject as the resource, added unchanged.
  • if it has a different subject, a SubjectError is raised.
