Hoi,
Do I understand correctly that the information is all based on Wikipedia information and that a large part is NOT in Wikidata..

Hi Gerard,

This dataset originates directly from Wikidata so it's only statements that exist in Wikidata atm.
With the mapping process we map Wikidata properties & classes to the DBpedia ontology and transform the statements accordingly.

For instance
wdt:Q42 wkd:P31 Q5 ;
  wkd:P569 "11-03-1951"^^xsd:date.

will be transformed to 
dbw:Q42 rdf:type dbo:Person; # plus all transitive types from the DBpedia ontology
  dbo:birthDate  "11-03-1951"^^xsd:date.
 
Can you say something about the mapping of the missing statements to DBpedia.

How hard would it be to include the basic information about people like day of birth/death ??

If your point is to include missing Wikidata statements from DBpedia, this can be a step towards towards this goal since now it is easy to compare the differences.

Best,
Dimitris
 
Thanks,

Dear all,

Following up on the early prototype we announced earlier [1] we are happy to announce a consolidated Wikidata RDF dump based on DBpedia.
(Disclaimer: this work is not related or affiliated with the official Wikidata RDF dumps)

We provide:
 * sample data for preview http://wikidata.dbpedia.org/downloads/sample/
 * a complete dump with over 1 Billion triples: http://wikidata.dbpedia.org/downloads/20150330/
 * a  SPARQL endpoint: http://wikidata.dbpedia.org/sparql
 * a Linked Data interface: http://wikidata.dbpedia.org/resource/Q586

Using the wikidata dump from March we were able to retrieve more that 1B triples, 8.5M typed things according to the DBpedia ontology along with 48M transitive types, 6.4M coordinates and 1.5M depictions. A complete report for this effort can be found here:
http://svn.aksw.org/papers/2015/ISWC_Wikidata2DBpedia/public.pdf

The extraction code is now fully integrated in the DBpedia Information Extraction Framework.

We are eagerly waiting for your feedback and your help in improving the DBpedia to Wikidata mapping coverage

Best,

Ali Ismayilov, Dimitris Kontokostas, Sören Auer, Jens Lehmann, Sebastian Hellmann
