i've written a few blog posts lately on semantic mappings, SSSOM, JSKOS, and automated assembly of data and knowledge. i'm also always very proud to do this by hand, without AI

2. SSSOM and JSKOS: https://cthoyt.com/2026/01/15/sssom-to-jskos.html

This week, our colleagues Hossen Beygi Nasrabadi and @joerg participated (and co-organised) the Platform Material Digital Hackathon at Bundesanstalt für Materialprüfung (BAM) in Berlin. Goal was to make progress on the next version of the PMDco ontology, a mid-level ontology for materials science engineering.

This poster is presented at CoRDI 2025 in Aachen, Germany.

The National Research Data Infrastructure (NFDI) initiative has led to the creation of consortia spanning all scientific disciplines in Germany. Each consortium develops customized research data infrastructures tailored to its domain-specific requirements. While addressing these individual needs, achieving interoperability remains an important objective of the NFDI, as it ensures a cohesive and sustainable approach to research data management across disciplines.

To support cross-domain interoperability, NFDIcore has been developed as a mid-level ontology designed to represent metadata about NFDI resources, including research data, persons, organisations, projects, standards, services, and guidelines. Aligned with NFDI's objectives, NFDIcore provides a structured, unified framework to streamline the management, organisation, and integration of research data across diverse scientific fields. By adhering to recognised data standards, NFDIcore enhances data accessibility, facilitates effective sharing, and promotes reuse, fostering more efficient collaboration and sustainable data practices within the broader research community. Furthermore, NFDIcore represents the NFDI community structure, including projects, services, and partnerships, and allows for consistent description and referencing of data generated by NFDI partners.

Hossein presenting at the EMMC. He is pointing to the projected slide depicting the 27 NFDI consortia. The audience is watching.

The MatWerk ontology MWO 3.0 is based on BFO2020, IAO, and PMDcore 3.0. It serves as a domain-level ontology representing (research data) resources of the NFDI-MatWek consortium.

An overview over the main classes of the MatWerk Ontology, embedded in a class hierarchy under BFO2020 (top level ontologies) and NFDIcore & PMDcore (mid-level ontologies).

We are contributing to the design and implementation of the PMDcore ontology, focussed to represent the entire domain of materials science - as well as to MatWerk Ontology, which is based on NFDIcore ontology (also provided by our group) to represent research data from the NFDI-MatWerk consortium. All ontologies are BFO2020-compliant.

In our ISE seminar today our colleague Hossein Beygi Nasrabadi is presenting the current state of the #NFDIMatWerk ontology - MWO. In the beginning, he is introducing two large #materialsscience related projects on digitalisation and research data management: Platform Material Digital (PMD) and NFDI-MatWerk.
