Hi Dimitry, I am not quering FOR the wikibase_item, I want to query WITH the wikibase_item as a parameter. Sorry if I was unclear.

If you look at the json response for that query, you can see wikibase_item present in the pageprops object. -Dmitry On Wed, May 20, 2015 at 9:01 AM, Johan Mijs <johan.mijs@bibnet.be<mailto:johan.mijs@bibnet.be>> wrote: Hello, we here at Bibnet (a government agency working for public libraries) in Brussels greatly admire your work on the Wikidata project!

Wonderful! Thx R. We indeed can use the wikidata api as a resolver to get the Wikipedia sitelink.
