  1. Good morning Dubrovnik! ESWC 2026 - the 23rd European Semantic Web Conference is starting today. Looking forward to visionary and inspiring keynotes, presentations, and posters, esp. addressing the question on how #SemanticWeb technologies will survive (or even prevail...) the current 3rd wave of #AI

  6. This is Koblenz Hbf, the main train station in #Koblenz, #Germany. I am waiting for the train to Stuttgart. This is the third time @Ayenkantun and I visited Koblenz. This time we traveled to attend Philipp Seifer's PhD defense. I co-author several papers with him about #SPARQL #KnowledgeGraphs #SHACL #SemanticWeb He did a great defense! I am very happy!

  7. Most data comes from closed-world systems — forms, sensors, logs — with known schemas. Yet the RDF community often says: adopt the full semantic web stack or nothing.
    My latest post explores practical RDF for closed-world systems:
    - When closed-world makes sense
    - Real examples: sensors, IoT, forms
    - How Netflix uses RDF+SHACL at scale
    - New SHACL 1.2 features

  9. There are many benefits when the inference rules are included in the knowledge graph. One benefit is the decoupling of data and application. It lowers the cost of integration and the cost of change. Another is the improved data governance.

    A third one is the gain in flexibility

  11. 📜 New essay on Link&Think

    Rules are usually in the application layer.
    With #SHACL rules, they can be part of the graph, and then, apart from simplicity and speed, they can bring other benefits coming from data-application decoupling.

    Part 1 is now available.

  12. Tired of the LLM noise? Let’s shift attention to something fully deterministic – rules running over a knowledge graph.

  13. I have reviewed many #SHACL shape graphs over the last few years. There are some error patterns as well as exotic errors. And recently, I've noticed some very different patterns of LLM-generated errors.

    Declarative code errors tend to be semantic illusions -- they mirror the user’s intent linguistically but diverge logically. Procedural errors, instead, are often syntactic or structural.

    "We present the first comprehensive semantic formalization of MIRAGE guidelines through an integrated RDF ontology framework comprising the MIRAGE Ontology and MIRAGE-DCAT3 vocabulary.

  31. 🏆 Honored to receive the IFIP TC2 Manfred Paul Award (2024) together with Kashif Rabbani and @kuzeko for our VLDB 2023 paper "Extraction of Validating Shapes from Very Large Knowledge Graphs".

    We propose a method to generate #SHACL shapes from large knowledge graphs — scalable to billions of triples, mining meaningful patterns based on support and confidence, and enabling effective data validation and quality assessment at scale.

  39. RDF people: why does everyone still use RDFS and not SHACL for writing schemas, when all the actual validation tools are for SHACL?

    Are there even any RDFS validators? I can't find any.

There are no breaking changes, only new features, but to indicate that this package is production ready, the version was lifted from 0.x to 1.x. Thanks to the #comunica library [2], support for #sparql constraints was added. Along with that feature, custom validation support was added.

    You can try the current state in your browser at the playground.

    There are a few Edge cases that do not yet work, but this is in progress.

    A big thanks goes to the #comunica developers, who developed the SPARQL engine, which does the heaving lifting behind the scenes.

  46. In our next #DigitalHistoryOFK, Ingo Frank presents the #DigiKAR project, which develops & uses innovative data modelling & visualization techniques for early modern places in the #HolyRomanEmpire. The talk will focus, i.a., on the use of #SHACL to create ontology design patterns & on the discussion of how to deal with the vagueness & uncertainty typical of historical sources.
