Retracted articles cited in Wikipedia

Last week, the Wikidata and Sister Projects event tooks place. The presentations are recorded, and I strongly encourage you to check the schedule. One presentation I liked (there are more), was the one by Mike Peel with the title “Best practices for reusing Wikidata’s data in the Wikimedia Projects”. At some point he walks us through the {{Cite Q}} template, around 26:07. 5 minute read

ICCS2025: back in Noordwijkerhout

This week the 13th International Conference on Chemical Structures took place (see also this Scholia overview or this overview of the full ICCS history). This is the conference I first joined 20 years ago as a PhD student presenting a poster (see these past blog posts). Of course, I am actually co-organizer nowadays (actually, co-treasurer). Organizing a meeting with just over 200 participants, and I like to thank Gerard and Willem in particular, but also Pieter, Marcus, Frank, Jenke, and Frans Koeman who has helped us during the past three events. 1 minute read

New preprint: "Scholia Chemistry: access to chemistry in Wikidata"

Two week ago I uploaded a paper that has been in the works for some time. In fact, I first mention it as conference paper for the special issue of the 11th International Conference on Chemical Structures, you know, the meeting held in 2018, of which the 13th edition starts in 7 days. I had a poster at that conference which I described in this blog post. 4 minute read

INTOXICOM Workshop #4: Training Materials for Toxicology

INTOXICOM is an ELIXIR Toxicoloy Community (doi:10.12688/f1000research.74502.2) implementation study, organizing five workshops, each one with a different topic. The first three workshops were in Utrecht (doi:10.37044/osf.io/un2rw), Basel, and Uppsala. The fourth workshop has the theme training material and will be held in Birmingham (thanks Iseult!). And one aspect of that is to make existing training material from toxicology projects indexed and therefore more FAIR. 1 minute read

One Million IUPAC names #2: the 100 thousand milestone

The April 2025 Scholia hackathon

This is the third weekend I am working on Scholia, the first two part of the April 2025 hackathon. It follows the hackathons last year October and November hackathons. There is some urgency for this unpaid work, because Wikidata is splitting the RDF into two SPARQL endpoints (see this The Signpost and this post by Finn). This split has happened, but there is a legacy server for tools that have not been upgraded. 3 minute read

Updating links to blogs: Peter Murray-Rust

One reason to move my blog from Blogger to a git-backed repository is that I can update links but that the version history shows exactly what change was made. I have been using three icons: when I can find a new URL for the website, I use ; when I cannot find a new URL, but the old URL is in the Internet Archive, I use a ; finally, if I cannot find anything to replace the broken link, I use . For example, the blog of Rich Apodaca is now archived, and I have been updating the many links to his (still running) blog to use DOI links. That has the added benefit of making blog-to-blog citations more FAIR. 2 minute read
