We are happy to announce the release of the 1.2 version of OntoWeaver, the tool that sits on top of BioCypher and allows to easily make independent adapters parsing structure data, from just a simple declaration of a mapping: https://github.com/oncodash/ontoweaver/releases/tag/v1.2.0

The main new feature is adapters for structured documents: OWL (ontology files' populated graph), XML and JSON documents, and some new high-level information fusion functions.

The package is available on PyPI, now in the BioCypher community: https://pypi.org/project/ontoweaver/1.2.0/

Our colleague @epoz has given a presentation at the KnowledgeCamp 2025 barcamp of the Gesellschaft für Wissensmanagement in Berlin with the title "From Data to Information and Knowledge", in which he tried to extoll the virtues of RDF and Linked Open Data, and our work in @nfdi4culture

Yesterday, I had the honor to deliver an invited talk with the title "Convenience vs Competence: the Evolving Role of Foundational Knowledge in AI-Driven Research" at the new year's receiption of the computer science faculty at Friedrich-Schiller-Universität Jena. Very happy to be at the place again, where I did my first PostDoc more than 20 years ago and meeting many old friends. :)

New research shows unified ontologies let agentic AI reason seamlessly across suppliers and regulators, boosting continuous learning and nested insights. Discover how LLMs, Google’s approaches, and Karp’s models converge in open‑source knowledge graphs. Dive into the details! #AgenticAI #Ontologies #KnowledgeGraphs #ContinuousLearning

#Buddhism and #QuantumPhysics both challenge classical views of independent, permanent entities. #Buddhist notions like #DependentOrigination and #emptiness hold that phenomena lack inherent essence and exist only relationally. #QM shows #reality as probabilistic & context-dependent, w properties emerging through interaction. Though methodologically distinct, both unsettle substance-based #ontologies and stress the relational nature of existence.

Probability density clouds for an electron in the hydrogen atom, shown for increasing principal quantum numbers
n
from top to bottom and for different orbital types across the bottom row (
s
,
p
,
d
). The colored lobes do not represent solid particles, but regions where a position measurement is more or less likely, so that what we call an “electron” appears as a structured pattern in a probabilistic field rather than a tiny localized object. This quantum picture of matter as relational and distributional, rather than as composed of intrinsically independent substances, provides a natural point of contact with the Buddhist analysis of phenomena as conditioned, empty of fixed essence, and defined by their dependencies.

We are happy to welcome @cthoyt from RWTH in today's #nfdicore playground talking about "Bridging the Gap from Biomedical to Domain-Agnostic Semantics".

Besides others, he is demonstrating that our #nfdicore ontology is registered at Semantic Farm (= an open source, domain-agnostic, community curated semantic space registry, meta-registry, and compact identifier resolver.)

Conceptual Overlap, Redundancies, and Discrepancies
referring to
a) Redundancies due to same subject (e.g., aspirin) between ChEBI. DrugBank, and PubMed
b) Redundancies due to different topic specificity (as e.g. between IDOMAL, IDOCOVID19, CIDO, VIDO, etc.)
c) Redundancies from highly generic resources (UMLS, MESG, NCIT)

Partial structure of MWO classes (green) mapped onto the class hierarchies of top-level BFO2020 (red), and mid-level IAO (purple), NFDIcore (blue), and PMDco (yellow) ontologies.

An ontology is a map that connects people, documents, events, processes, and meanings. It doesn’t just “classify” things it helps a system understand why they are related and what they actually represent.

MaterialDigital General Assembly 2025 in Berlin. The presentation slide is titled "When Data Talk".

Ontology is shaping up to be the buzzword of 2026 because they are offering what #LLMs are lacking: formal grounding

LLMs offer creativity but need logical grounding. Ontologies provide this formal structure, anchoring meaning and unifying diverse data sources into a single semantic layer. They are essential for achieving precision and are one of the most reliable defense mechanisms against #AI #hallucination.

The image is a political cartoon that illustrates a perceived shift in the artificial intelligence (AI) community's perspective on the importance of "ontology" between 2023 and 2026.
- 2023: The term "ontology" was widely rejected in the AI field, as depicted by a stamp machine smashing documents labeled "ontology rejected".
- 2026: The cartoon predicts that "ontology" will be a required component for "The Future AI Foundation," as shown by a stamp machine approving documents with the label "ontology required".
Context: Ontology in AI refers to a formal naming and definition of the types, properties, and interrelationships of the entities that exist for a particular domain of discourse, which can help structure AI systems.
Foundations: Several real-world AI foundations and services exist, focused on areas like research, standards, and secure deployment of AI models.

Last week, our colleague @heikef participated at the 4th Ontologies4Chem Workshop in Limburg, jointly organized by @NFDI4Chem @NFDI4Cat Beilstein-Institute and PSDI. Goal of the workshop was to agree on a "canon" of recommended chemistry-related ontologies for metadata annotation of FAIR research data.

The #RomanticPeriodPoetryArchive knowledge base is accessible via #SPARQL, enabling semantic queries and data integration. This infrastructure underpins the interactive "Networks"-view on the website and is the basis for further computational analysis and application development.

Did you ask yourself how the #TerminologyServices landscape looks like in the #NFDI or in the whole DACH region?

Than have a look to our paper. The paper belongs to our talk at the #ESciTage2025 . You will also get some insights in #terminologies, #ontologies and user needs for #FAIR #RDM .
