We added 80 new records, updated 54 records, and made a constellation of improvements and updates to the Semantic Farm and Bioregistry in the first two weeks of October 2026. This post gives more detail and links to external resources for further reading. For new readers, a brief reminder that the Semantic Farm is a domain-agnostic generalization on the Bioregistry to better serve other natural sciences, engineering sciences, and humanities and social sciences communities, especially within the context of the NFDI. ## Highlights 1. Records were added for ontologies from the World Avatar, which support multiscale modeling from the molecular level to municipal systems and weather patterns. I wrote about this in detail in my previous post 2. A record describing the European Synchrotron Radiation Facility (ESFR) Experimental Techniques Ontology (ESRFET) was added and members of DAPHNE4NFDI suggested several improvements to physics-related ontologies, including the NeXus Ontology (`nexus`) (also used DAPHNE4NFDI, FAIRmat, and NFDI-MatWerk) and the Photon and Neutron Experimental Techniques Ontology (`PaNET`)). This demonstrates the relatively low barrier for community involvement in the Semantic Farm and that NFDI consortia and their respective members can take initiative to maintain records describing both their first-party resources and third-party resources they use. 3. Improved workflow for ingesting and aligning records for ontologies in the Open Biological and Biomedical Ontology (OBO) Foundry. I wrote about this in detail here. 4. Implemented a draft workflow for calculating ontology reuse as part of NFDI Section Metadata Working Group for Ontology Harmonization and Mapping’s agenda for summarizing ontology usage across NFDI consortia. See the pull request and results. ## New Prefixes Aside from the 74 new records added for ontologies from the World Avatar project, six new records were added, five of which cover cell and cell line resources appearing in Cellosaurus cross-references.
