Hi Karen, Thanks for all your work on the RDF metadata in openlibrary. It is much appreciated. As I parse it, we have here the triples (in almost-turtle): W <http://vocab.org/frbr/core.html#Manifestation> M1, M2, M3, ... . M1 a <http://rdvocab.info/RDARelationshipsWEMI/workManifested> . I think it should be: W <http://rdvocab.info/RDARelationshipsWEMI/workManifested> M1, M2, M3, ... . M1 a <http://vocab.org/frbr/core.html#Manifestation> . Is that correct? Since all the manifestations are also retrievable, you could probably get away with even less metadata about each manifestation, but the title & date seems good to have. 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]
