Wikipedia, Wikidata, and citations

As part of an exploratory census of citations on Wikipedia, I have generated a complete (yeah, right) list of all scientific publications cited on Wikispecies, English and German Wikipedia. This is done based on the rendered HTML of the respective articles, and tries to find DOIs, PubMed, and PubMed Central IDs. The list is kept […]

Why I didn’t fix your bug

Many of you have left me bug reports, feature requests, and other issues relating to my tools in the WikiVerse. You have contacted me through the BitBucket issue tracker (and apparently I’m on phabricator as well now), Twitter, various emails, talk pages (my own, other users, content talk pages, wikitech, meta etc.), messaging apps, and […]

The File (Dis)connect

I’ll be going on about Wikidata, images, and tools. Again. You have been warned. I have written a few image-related Wikimedia tools over the years (such as FIST, WD-FIST, to name two big ones), because I believe that images in articles and Wikidata items are important, beyond their adorning effect. But despite everyone’s efforts, images […]

Playing cards on Twitter

So this happened. Yesterday, Andy Mabbett asked me on Twitter for a new feature of Reasonator: Twitter cards, for small previews of Wikidata items on Twitter. After some initial hesitation (for technical reasons), I started playing with the idea in a test tweet (and several replies to myself), using Andy as the guinea pig item: […]

Dystopia 2030

The year is 2030. The place is Wikimedia. Maybe. English Wikipedia was declared complete and set to read-only, after the creation of the 10 millionth article ([[Multidimensional Cthulhu monument at Dunwich]], including pictures from multiple dimensions). This coincides with the leaving of the last two editors, who only kept going for the honour of creating […]


tl;dr: I wrote a quiz interface on top of a MediaWiki/WikiBase installation. It ties together material from Wikidata, Commons, and Wikipedia, to form a new educational resource. I hope the code will eventually be taken up by a Wikimedia chapter, as part of an OER strategy. The past There have been many attempts in the WikiVerse to […]

All your locations are belong to us

A recent push for a UK photography contest reminded me of an issue I have begrudged for a quite a while. On the talk page for that contest, I pointed to several tools of mine, dealing with images and locations. But they only show aspects of those, like “Wikidata items without images”. What about the others? WDQS can show maps of […]

Livin’ on the edge

A few days ago, Lydia posted about the first prototype of the new structured data system for Commons, based on Wikidata technology. While this is just a first step, structured data for Commons seems finally within reach. And that brings home the reality of over 32 million files on Commons, all having unstructured data about them, in the […]


Wikipedia has language editions, Wikidata has labels, aliases, descriptions, and some properties in multiple languages. This a great resource, to get the world’s knowledge in your language! But looking at the technical site, things become a little dim. Wikimedia sites have their interface translated in many languages, but beyond that, English rules supreme. Despite many […]

First image, good image?

For a while now, Wikimedia pages (usually, Wikipedia articles) have a “page image”, an image from that page used as a thumbnail in article previews, e.g. in the mobile app. While it is not entirely clear to me how this is image is chosen, it appears to be the first image of the article in […]
