A paper of mine was published in the Journal of Open Humanities Data: "Developing a Data Model for Theatre Productions in a Wikibase Instance: A Case Study Approach" ☺️ 🎭
I developed a data model that can map #productions, #costumes, spatial settings, and interactive audience elements. Implemented in a #Wikibase instance, it enables #SPARQL queries on these elements of productions as well as roles, and casts.

from the linked GitHub issue: "Here is a demo of QLever handling one trillion triples on a single commodity PC: https://qlever.dev/one-trillion . That is more than fifty times larger than the current Wikidata" #sparql #rdf #opensource
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.

En er is een zesde provincie bij op #Mastodon: @provinciedrenthe
Al sinds 2025-10-16, maar toch nog welkom!
Zie hier een kaartje, gebaseerd op #wikidata:
I made once this #wikidata #sparql query for all candidates for the Dutch parliament that have a #Mastodon handle:
Maybe I will see how to change the query so that it will list only the current Dutch #MP's that have a Mastodon account.
Similar things could be done for Twitter accounts. I've no idea how current the Twitter-handle info in wikidata is. I sometimes update Mastodon handles for Dutch politicians in wikidata.

📍 Bari, Italy 🇮🇹, please repost to help reach potential authors!
yesterday evening work with @EvoMRI on the @wdscholia instance on Toolforge. We noted that our main instance only shows half of the results, only @wikidata 'main' part. The 'scholarly' articles part are no longer there. That day has been pending.
We seem very close. I wrote up a status 3 weeks ago: https://chem-bla-ics.linkedchemistry.info/2025/12/31/rescuing-scholia-2-getting-close.html
For this week, plz use https://qlever.scholia.wiki/
We put a banner on the #toolforge instance
@jerven these owl:sameAs triples should now be live in the @wikipathways SPARQL endpoint (https://sparql.wikipathways.org/) and the PlantMetWiki endpoint (https://plantmetwiki.bioinformatics.nl/)
Snowman, a static site generator for #SPARQL backends has had another release!
https://github.com/glaciers-in-archives/snowman/releases/tag/0.8.0
In questo articolo mostriamo una pipeline controllata per tradurre domande in linguaggio naturale in query #SPARQL eseguibili su #wikidata
After a lot of hours and trial and error, I've managed to create a digital interactive version of the Down Survey map for County Kilkenny on #uMap: http://u.osmfr.org/m/1340327/ using #Wikidata. Many thanks to all the people who have created #SPARQL queries for me in the past - I was able to modify some of them for this purpose. It doesn't have all the parishes and all the castles, but I actually discovered some unrecorded (by the NMS) watermills (not included...) and castles along the way. 😇
RE: https://hachyderm.io/@LeafyEricScott/115850226576380708
#SPARQL turned out to not be necessary for this project after all, thank goodness.
@jerven okay, rough estimate of the number of owl:sameAs links now in the @wikipathways RDF (part of the release on the 10th):
- 1250+ owl:sameAs to SwissLipids
- 5000+ owl:sameAs to @lipidmaps.bsky.social
- 1600+ owl:sameAs to @rhea-db.bsky.social
- 77k+ owl:sameAs to UniProtKB
(powered by @wikidata via their SPARQL)
@jerven I had not answered your question yet, and no patch needed, but just to answer it:
1. the original (theseus) code is here: https://github.com/wikipathways/GPML2RDF/tree/main which is used for https://sparql.wikipathways.org/
2. the new libGPML-based code is here: https://github.com/egonw/org.pathvisio.io.rdf which is used for https://plantmetwiki.bioinformatics.nl/
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
