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
1. SSSOM and Wikidata: https://cthoyt.com/2026/01/08/sssom-to-wikidata.html
2. SSSOM and JSKOS: https://cthoyt.com/2026/01/15/sssom-to-jskos.html
3. SSSOM and BioPortal: https://cthoyt.com/2025/11/23/sssom-from-bioportal.html
4. semantic mappings enable automated assembly of data and knowledge: https://cthoyt.com/2026/01/16/mappings-for-automated-assembly.html
At the 4th Ontologies4Chem Workshop in Limburg an der Lahn, I proposed an initial crosswalk between the Simple Standard for Sharing Ontological Mappings (SSSOM) and the Wikidata semantic mapping data model. This post describes the motivation for this proposal and the concrete implementation Iโve developed in sssom-pydantic.
We are happy that our new paper "NFDI MatWerk Ontology (MWO): A BFO-Compliant Ontology for Research Data Management in Materials Science and Engineering" is being published by Advanced Engineering Materials as #openaccess
This is joint work with Hossein Nasrabadi, @enorouzi Kostiantyn Hubaiev, @joerg and @lysander07

2nd contribution by @fizise team is presented by @enorouzi: "AI4DiTraRe: Building the BFO-Compliant Chemotion Knowledge Graph", which is a #BFO aligned, scalable #knowledgegraph of experimental #chemistry data that facilitates #interoperability, #provenance tracking, and #Reasoning supporting AI-driven research and discovery. Joint work w @joerg Nicole Jung

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