Released wikibase-cli v20.0.0 ✨

It includes a new command – `wb graph-path` – to find the path between a subject and an object via a given property, on the entities relations graph.

Package: https://www.npmjs.com/package/wikibase-cli
Changelog: https://github.com/maxlath/wikibase-cli/blob/main/CHANGELOG.md#2000---2026-02-11

That's a list I've been looking for for some time: https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format#WDQS_data_differences

It shows the differences between the RDF source of a Wikidata item and the way it's stored in the RDF actually used in #Wikidata Query Service #WDQS (and in #qlever as well, apparently).

I'd stumbled over the fact that "?item a wikibase:Item" doesn't return any results. The link above explains why.

What is in #wikidata? The answer to this question on the Wikidata:Statistics page (https://www.wikidata.org/wiki/Wikidata:Statistics) hasn't been updated for a while. This #sparql query run in #qlever provides a snapshot of the current situation (it's not entirely identical as P31/P279* times out even in qlever but it conveys the idea): https://qlever.dev/wikidata/k9TJoh

Articles have the lion's share, paintings and manifestations of wirtten works are well represented, though.

Für einen kurzen Impuls habe ich mir die Präsenz der Stiftung Preußischer Kulturbesitz im #Wikiversum angesehen und ein paar Daten dazu zusammengetragen. Neben #qlever, #petscan und #glamorgan habe ich inbesondere versucht, die Revisionshistorie der Items auszuwerten. Da ließe sich sicher noch mehr herausholen. Wenn also jemand Ideen hat, gerne! Präsentation, Daten und Code zum Nachbasteln gibt es unter https://doi.org/10.5281/zenodo.18380310

There will be changes in the week of January 20th 2026 regarding the WDQS graph split and sunsetting of the legacy service. There is a https://qlever.scholia.wiki/ mirror running with QLever as backend with the full Wikidata content. This mirror is part of an evaluation of alternatives to Blazegraph.

new blog post: "Rescuing @wdscholia #2: getting closer" https://chem-bla-ics.linkedchemistry.info/2025/12/31/rescuing-scholia-2-getting-close.html https://doi.org/10.59350/6t2qh-2f839

"But we are getting close. So, please give qlever.scholia.wiki a go, and let us know your observations. As Linus’s law writes: Given enough eyeballs, all bugs are shallow."

Replying to this post makes it show up in my blog.

we have moved closer to having the option to switch to a #QLever backend. Beta testers can assist by exploring the interim QLever-backed Scholia instance: https://qlever.scholia.wiki/

Any issues can reported here (we appreciate it!): https://github.com/ad-freiburg/scholia/issues
