I am Lucas Werkmeister (Lucas Werkmeister (Q57387675), he/him), a software developer and Wikidata enthusiast.

I don’t check my watchlists on most wikis very frequently – please {{ping}} me!

Other accounts[edit]

User:Lucas Werkmeister (WMDE)
I work at Wikimedia Deutschland (as an intern from April 1, 2017 until March 31, 2018, as a working student from April 1, 2018 until October 31, 2018, and as a full-time employee since November 1, 2018), and use this account for any related activity.
The Wikimedia account for @WikidataFacts (Twitter or Mastodon). (Formerly also called User:WikidataFacts, but renamed when someone at German Wikipedia complained about the “Wikidata” in the name.) Back when I registered this account, WikidataFacts was still anonymous, so I used it e.g. to register for a few events; otherwise I probably would’ve just used my clear-name account and not registered a separate one. But now that it exists, I still use TweetsFactsAndQueries for some query-specific activity.
User:Lucas Werkmeister CI
For automated tests of different tools. “CI” stands for continuous integration; the systems where these automated tests run shouldn’t have access to my privileged main account.
User:Lucas Werkmeister CI (WMDE)
The WMDE version of a CI-only account.

Lucas Werkmeister, Lucas Werkmeister CI and Lucas Werkmeister (WMDE) also exist on the Beta Cluster.


I was a member of CAcert Inc. until June 30, 2016.

I worked on the Ceylon programming language until ca. mid-2018.

I am a founding member of the World Privacy and Identity Association.

I work at Wikimedia Deutschland, see above.


In my private time (i. e., not as part of my WMDE work), I’ve written the following tools:

  • Wikidata Lexeme Forms, a tool to create Wikidata lexemes with a set of forms (e. g. declensions of nouns)
  • Wikidata Image Positions, a tool to show and add “relative position within image” qualifiers on “depicted” statements of Wikidata items
  • Wikidata Shape Expressions Inference, a tool to infer schemas from sets of exemplary Wikidata items (part of my master thesis)
  • Wikibase to RDF, a tool to convert entities from Wikibase’ native JSON format into RDF
  • SpeedPatrolling, a tool to assist in patrolling recent changes on Wikidata
  • QuickCategories, a tool to quickly add and remove categories from pages
  • AC/DC, a Wikimedia Commons gadget to add statements to files in bulk
  • PagePile Visual Filter, an auxiliary tool for PagePile to visually select a subset of a pile
  • Ranker, a tool to edit the rank of multiple statements at once

If you’re interested in co-maintaining any of them, please let me know: I’d be very happy to reduce the “bus factor” for these tools by finding other people who can take care of them. This doesn’t necessarily require strong programming skills: sometimes you might just need to restart the web service, and the most common maintenance task for the Lexeme Forms tool, for example, is to add new templates provided by the community to the list of templates, which is essentially a transcription task.
