    📢 LintedData 3.0.1 is released: https://gitlab.com/dlr-dw/linteddata/-/releases/v3.0.1 LintedData is a linter for RDF and Ontologies for easy use in CI pipelines. It checks for common violations of best practices in ontology engineering. Version 3.0.1 further reduces the need for configuration, and improves some checks. #RDF #Ontologies #KnowledgeGraphs #DataQuality #OntologyQuality #OntologyEngineering #LintedData

    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): &amp;quot;We think we know a thing only when we know its cause.&amp;quot; #eswc2026 #UnitsOfMeasur...

    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. 🔗 Ontology: https://w3id.org/d4co 🧑‍💻 Repository: https://gitlab.com/dlr-dw/d4co 📄 Paper Pre-Print: https://elib.dlr.de/224130/ #eswc2026 @eswc_conf #KG4S @kg4s #ontologies

    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. #ESWC2026 @eswc_conf #KnowledgeGraphs #LLM

    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.
