An alternative might be to create an expression URI and a manifestation URI for each OL edition. Some of these expressions will be duplicates, but in the future, if you wish, you or others could merge them or use sameAs information to indicate that they identify the same expression. <http://openlibrary.org/works/1> a frbr:Work ; frbr:realization <http://openlibrary.org/editions/2#Expression> . <http://openlibrary.org/editions/2#Expression> a frbr:Expression ; frbr:embodiment <http://openlibrary.org/editions/2#Manifestation> . <http://openlibrary.org/editions/2#Manifestation> a frbr:Manifestation . This will create too many expressions, which is a little annoying; but it will not create too few, which would be a real problem. best, Erik _______________________________________________ Ol-tech mailing list [email protected] http://mail.archive.org/cgi-bin/mailman/listinfo/ol-tech To unsubscribe from this mailing list, send email to [email protected]
