Rescuing Scholia #3: We did it! It was not a set up, when I openly wondered if we would be able to rescue Scholia in time. I honestly did not know. Three weeks and some serious hacking by an international team later I was more optimistic. Actually, just before christmas, we started writing a SWAT4HCLS 2026 demonstration abstract. This was accepted and you can read the _Scholia 2026: Compliance with SPARQL 1.1_ preprint here and here. This paper describes the work that had to be done, and I am deeply grateful to everyone who contributed with smaller or bigger contributions (Daniel, Peter, Konrad, Johannes, Lars, Wolfgang, Hannah). I am merely first author for the demo, and just another contributor to the long series of patches, in a branch started by Prof. Hannah Bast. The work actually started long before that, with the _Robustifying Scholia_ grant (see doi:10.3897/rio.5.e35820), where we explored alternatives. The Wikidata graph (RDF) split has been long coming, and I can recommend this recent The Signpost article by Lane for a good overview. So, this would not have been possible with the many people who contributed over the years. But this last sprint really made a difference. The developments of the QLever software in the past year are very important, and the SPARQL endpoint we run now is live updated, just like we knew from the Wikidata Query Service (WDQS). Recent improvement allowed us to replace all the Wikidata and Blazegraph specific aspects of the SPARQL queries, and good discussions let to pragmatic approaches to keep localization features Scholia had for displaying query results from Wikidata. The work is not completed, however. All queries are SPARQL 1.1 now, but some can still be further optimized, and some still need some fixing. For example, I still spot some QIDs here and there, instead of the localized labels that should be shown instead. Also, we are actively looking in getting everything running again on WMF servers (see this overview issue), so that _scholia.toolforge.org_ works again. For now, however, please use qlever.scholia.wiki.

Scholia

When I want to know about a subject like the African green wall, I seek publications on the subject using #Scholia .. At this moment 3 articles... :( One of them, the 2025 one, I just added. scholia.toolforge.org/topic/Q387790

Bei der etwas anstrengenden #Orcid Maske ist man ja versucht, seine Literatur einfach nur in #WikiData zu erfassen und im Orcid auf einen #Scholia Link zu verweisen. Nur hat man dort wiederum meist das Problem, dass die übergeordneten Werke zuerst modelliert werden müssen....

Scholia

Another author known to #Wikidata .. this is the #Scholia scholia.toolforge.org/author/Q1366...

Scholia

Attributed many publications, am adding publications, it will show in his #Scholia .. Could we have a picture to include please? scholia.toolforge.org/author/Q9643...

Screenshot of Ammar's Snorql UI, here wrapped around the Wikidata SPARQL instance by the QLever team, federating with the IDSM SPARQL endpoint for substructure searching, and using CDK Depict to convert the SMILES into 2D depictions in the results tables

oolonek⁩ reminded me how cool IDSM is (see https://doi.org/10.1186/s13321-021-00515-1 and works wonderfully in the rich chemistry SPARQL world (see https://doi.org/10.1186/1758-2946-3-15

Here I mashed up @wikidata, IDSM, QLever, @cdk Depict, and Ammar […]

In nutrion, ultra-processed food is quite a relevant subject. At #Wikidata it is now a subject on a substantial number of items.. With #Scholia it looks like this scholia.toolforge.org/topic/Q48931...
