Re: [Wikidata] DBpedia-based RDF dumps for Wikidata

2015-05-28 Thread Dimitris Kontokostas 
Thank you Hugh,

This is definitely an area where we need further feedback from the
community.

Most of these links are DBpedia language links. The majority of the DBpedia
links are not dereferencable and are based on the different DBpedia
language editions provided as RDF dumps only.

In this release we decided to provide them all for completeness but we are
very open to other suggestions.

Best,
Dimitris

Re: [Wikidata] Wikidata-l: List rename on Tuesday, 19th

2015-05-28 Thread John Lewis 
Hi,

The maintenance window has just closed and this was done in the window.

The new list lives under 'wikidata@lists.wikimedia.org' with a redirect
from 'wikidat...@lists.wikimedia.org'. This email has been sent to the
latter as a test of redirection.

Thank you to Rob Halsell for his work in the maintenance window.

Thanks,
John Lewis

Re: [Wikidata] DBpedia-based RDF dumps for Wikidata

2015-05-28 Thread Hugh Glaser 
Thanks Dimitris - well done to the whole team.

In case it helps anyone, I have brought up a sameAs store for the sameAs 
relations in this dataset alone:
http://sameas.org/store/wikidata_dbpedia/

In passing, it is interesting to note that the example URI, 
http://wikidata.dbpedia.org/resource/Q586 , has 110 sameAs URIs in this dataset 
alone.
What price now the old view that everybody would use the same URIs for Things?!

Best
Hugh
