Hi!
This works for the Wikipedia URL given above, but many
other don't
return a result, for instance:
https://en.wikipedia.org/wiki/Getty_Thesaurus_of_Geographic_Names
=> should be
http://www.wikidata.org/entity/Q1520117
This one is actually recorded as
https://en.wikipedia.org/wiki/Getty%20Thesaurus%20of%20Geographic%20Names
Not sure if it's a problem or not.
But the sitelinks should be updated now.
