If <DNB > URI> owl:sameAs <VIAF URI> it is easy :) DNB offers a file with CC0'd > RDF about people at then you are on the good site because they identify only *persons*. > https://wiki.d-nb.de/display/LDS/Dokumentation+des+Linked+Data+Services+der+DNB > although I keep getting HTTP 500 errors trying to request those files. which one? (And also, think of comment that on the dnb-wiki). BTW, you may want to use our SPARQL-endpoint, we have an index of the gnd. It is based on an old dump, though, I think it was April 2011: curl -d 'query= SELECT * FROM <http://lobid.org/gnd/> WHERE { <http://d-nb.info/gnd/100063462> ?p ?o . } ' http://lobid.org/sparql/ (this is rather unofficial and experimental. Ping me if it breaks. ) > The example file does show that there are owl:sameAs links in the RDF. > So in lobid.org, you treat the name as an RDF resource (that has a GND > URI)? Interesting. No offense intended, but does that make more sense > than using the literal value? its all about linking, isn't it ;) I mean, if it *is* an RDF ressource we can lookup its literal (actually we *do* that for subjects , see http://lobid.org/resource/HT014337912 (eng:subject = ger:Schlagwort)). But you are right, if we cannot make a lookup it does not make sense. So we are in hope that the dnb will also provide rdf for these name-identifiers. It would have had the advantage that if there are more ways to write down a name ("Goethe, Gethe, Göthe ..." ) we would not have to curate that by ourself. And we just telephoned with the dnb and there will be RDF for the not-individualised identifiers within the next month ! :) What if there are several Friedrich > Schillers and the names are split by the DNB into several persons? that is an important todo. Not that easy to do, though. If solved, it could help to create an authority file of publishers which I would love to see. > I have been thinking to do something similar when I'm ready to publish > my family tree as RDF, to relate names to their origins.

If you want to connect name and person that would be what you want: "name" is a literal and "person" the individualised URI of the person, e.g.: <http://d-nb.info/gnd/135539897> <http://d-nb.info/gnd/preferredNameForThePerson> "Elgin, Catherine Z." . -o _______________________________________________ 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]
