For instance, FOAF *defines* that foaf:mbox_sha1sum is an InverseFunctionalProperty (granted, only in the OWL Full sense). Never the less, the semantics that would result in an owl:sameAs can be declared inside the ontology. So maybe one way to pursue this would be to see if it's possible to write some OWL that would allow a reasoner to determine that two stories, even though they are identified with bnodes, are owl:sameAs.
