It might be safer to say that merging nodes is ontology specific.  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.
