Hi folks!
We need a full mapping of WD item -> enwiki sitelinks.
1. We extracted from Dbpedia 2015-04 all statements of the form
<http://dbpedia.org/resource/Northern_Ireland>
<http://www.w3.org/2002/07/owl#sameAs> <http://wikidata.org/entity/Q26>
And the count is 5882410
2. Checked with WDQ:
https://wdq.wmflabs.org/api?q=link[enwiki]&noitems=1
"items":6263098
6.08% are missing from DBpedia. That's a lot
How to get them from Wikidata?
3. WDQ doesn't seem to return sitelinks.
https://wdq.wmflabs.org/api?q=link[enwiki]&props=enwiki returns just item
numbers
4. The SPARQL endpoint doesn't seem to have them:
http://wdqs-beta.wmflabs.org/
prefix schema: <http://schema.org/>
select * {?x schema:about ?y}
returns nothing.
https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format#WDQS_data_d
ifferences
says "5. Depending on the instance of the service, multi-language labels and
sitelinks may or may not be supported."
I think this service doesn't have sitelinks: is there one that has them?
