Wikidata query service updater evolution
The Wikidata Query Service (WDQS) sits in front of Wikidata and provides access to query its data via a SPARQL API. The query service itself is built on top of Blazegraph, but in many regards is very similar to any other triple store that provides a SPARQL API. In the early days of the query […]

Infrastructure as Code for wbstack deployments
For most of its life wbstack was a mostly one-man operation. This certainly sped up the decision making process around features, requests, communication and prioritization, I also had to maintain a complex and young project supporting hundreds of sites on the side of my regular 8 hour day job. In order to ensure that I’d […]

WikiCrowd at 50k answers
In January 2022 I published a new Wikimedia tool called WikiCrowd. This tool allows people to answer simple questions to contribute edits to Wikimedia projects such as Wikimedia Commons and Wikidata.

Years later I realized that this was actually the documented way of pushing changes to Gerrit. As a little introduction to what this workflow looks, and a […]

Small commits
There are many blog posts and articles out there about making small git commits. I’m sure most people (including me) bring up the same few topics around why small commits are good and why we should all probably be making smaller commits. In this post, I’ll look at some of the key topics from my […]

Wikibase a history
I have had the pleasure of being part of the Wikibase journey one way or another since 2013 when I first joined Wikimedia Germany to work on Wikidata. That long-running relation to the project should put me in a fairly good position to give a high-level overview of the history, from both a technical and […]

Profiling a Wikibase item creation on test.wikidata.org
Today I was in a Wikibase Stakeholder group call, and one of the discussions was around Wikibase importing speed, data loading, and the APIs. My previous blog post covering what happens when you make a new Wikibase item was raised, and we also got onto the topic of profiling. So here comes another post looking […]

WBStack close and migration
The time is approaching for the end of life of the WBStack alpha platform (don’t worry, it’s still some months away, and there is a migration path to a new platform etc :)). In this post you’ll find an update on the current state of WBStack, another introduction to Wikibase.Cloud, some rough dates and connections […]
