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.

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.

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

European Semantic Web Conference is about to start. I am looking forward to an exciting and inspiring event. #eswc2026 @eswc_conf@sigmoid.social

@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.
