Dear all,

I have created a small SPARQL query service for Wikidata history. It is in a very early stage.

It currently stores metadata about each Wikidata item or property revision (contributor, timestamp, entity edited, previous/next revision of the given entity) and a part of the revisions content (wdt: direct claim relations and redirects). It allows to query the triples added and removed by a revision and query the full state of the Wikidata graph after any revision. The data loaded covers a range from the creation of Wikidata to July 1st 2018.

The help page : https://www.wikidata.org/wiki/Wikidata:History_Query_Service The query UI : https://wdhqs.wmflabs.org/

I hope it will be useful for doing interesting researches around Wikidata. Feel free to email me if you need help with it. If it is useful for many people I hope to be able to take time and get storage space to load more recent data and the missing parts of Wikidata items contents.

Best,

Thomas (User:Tpt)
