Atanas Kiryakov, President of Graphwise, in his keynote at ESWC points out a merging advantage of (re-)using public ontologies: LLMs already know these ontologies, which increases the interoperability of the data by making use of knowledge graphs as context easier and cheaper.

Very nice, the main-conference proceedings are already available during the conference.
📕🔒 ESWC 2026 Proceedings Part 1: https://doi.org/10.1007/978-3-032-25156-5
📕🔒 ESWC 2026 Proceedings Part 2: https://doi.org/10.1007/978-3-032-25159-6

Unfortunately they are not open access. But as usual, the conference website will provide the camera ready PDFs, too. Research, Resource, and In-Use papers are available there.
📑🔓 Free access main track papers: https://2026.eswc-conferences.org/program/accepted-papers/main-tracks/

Others are promised to follow soon.

Already yesterday, I presented at the ESWC 2026 Pre-Conference in the Knowledge Graphs for Sustainability Workshop (KG4S) the Design-for-Circularity Ontology (D4CO). Related artifacts are available online.

Recently, I was discussing about the pros and cons of different unit ontologies. However, I was not able to really express, why I am in favor of an ontology, which not only provides the direct conversion factors between units for direct application, but also provides the explanation for these values. In her keynote, Maria-Esther Vidal provided an explanation for my intuition (free after Aristotle): "We think we know a thing only when we know its cause." #eswc2026 #UnitsOfMeasurement #Ontologies

@cthoyt@scholar.social Thank you for the suggestion. I created an issue [1] about that. Under which license can the data dump [2] be reused? [1]: https://gitlab.com/dlr-dw/linteddata/-/work_items/203 [2]: https://github.com/biopragmatics/bioregistry/blob/main/src/bioregistry/data/bioregistry.json

LintedData is a linter for RDF and Ontologies for easy use in CI pipelines, we recently released. It checks for common violations of best practices in ontology engineering. GitLab: https://gitlab.com/dlr-dw/linteddata/ Docker: https://hub.docker.com/r/dlrdw/linteddata/ Today I present LintedData at the Helmholtz Metadata Conference 2026 demo session.

@benny@norden.social Spannend. Wikidata ist jetzt wichtig für SEO. Ich hoffe das führt zu weiterem Wachstum und nicht zur degenerierung des Graphen. Welche Vorraussetzungen muss denn ein Wikidata-Eintrag erfüllen, um nützlich für SEO zu sein? Reicht eine ID mit Label? Oder möglichst genau Klassifizierung und Verknüpfung mit anderen Entities über Statements? @nightrose@mastodon.online @wikidata@wikis.world #wikidata

Replying to @markwyner@mas.to

@markwyner@mas.to Did @Mastodon@mastodon.social GmbH formally join @w3c@w3c.social or the particular W3C working group? Even if the WG notes [1] sound like the former, the official members list [2] suggest the later. But maybe the list has not been updated yet?

In any case, that is good news.

@carbonwoman @bmftr_bund Über eine Ausstellung mit genau diesen Bildern hat @stefanmuelller bereits Ende letzten Jahres geschrieben: https://climatejustice.social/@stefanmuelller/115745386780490144 Mir ist völlig unverständlich, wie es jemand für eine gute Idee halten kann, Geschichte und Gleichstellung mit verzerrenden und Klischee-gefärbten Bildfälschungen vermitteln zu wollen.
