Stephen,
While you're waiting, you could get the owl:sameAs assertions in the reverse
direction from the VIAF data dumps. An N-TRIPLE form was added to the
processing about a week ago, which should make it easier to consume:
http://viaf.org/viaf/data/viaf-20130514-clusters-rdf.nt.gz
I don't see it listed as a void:dataDump inside the VoID dataset description
yet, but it should be soon:
http://viaf.org/viaf/data

Subject: Re: [Dbpedia-discussion] VIAF extraction?
I'm not sure I understand exactly. I don't see any VIAF information in the
owl:sameAs values for any of my test cases (e.g. Albert Einstein). I am able to
return results in both live.dbpedia.org/sparql<http://live.dbpedia.org/sparql>
and
dbpedia-live.openlinksw.com/sparql<http://dbpedia-live.openlinksw.com/sparql>
for dbpprop:viaf. It seems that only a small fraction of the wiki pages using
authority control have the dbpprop:viaf, dbpprop:lccn, etc. present in the
DBpedia Live dataset. Does it just take a long time for the delta to get
extracted from Wikipedia? I might just be confused about the extraction
process/timeline. While DBpedia Live includes some pretty recent additions
(e.g. http://live.dbpedia.org/page/2013_Xiamen_bus_fire) to wikipedia, some
relatively distant changes have not been reflected, such as the authority
control for persons (e.g. the VIAF on Kanye West which was added sometime in
late 2012).
Thank you for taking the time to respond; it's a really interesting subject and
I'd love to understand it better and hopefully add some value to the community.

We already have a pending pull request [1] to support automatic sameAs
links in Live but till then you can construct them yourself with a SPARQL
Construct or programatically
