OBI Release 2025-12-18

[James A. Overton]

Hi everyone,

A new OBI release is available:

- Versioned OWL: http://purl.obolibrary.org/obo/obi/2025-12-18/obi.owl
- Notes: https://github.com/obi-ontology/obi/releases/tag/v2025-12-18
- Branch: https://github.com/obi-ontology/obi/tree/v2025-12-18

This is the first release using COB as our upper level. Please report any problems here https://github.com/obi-ontology/obi/issues/1857. If you want to continue using BFO as the upper level, we will be maintaining a BFO version of OBI for some period. The current version is available at this PURL: http://purl.obolibrary.org/obo/obi/2025-12-18/obi-bfo.owl

Please see the notes for the full list of changes.

Best,

James
