The Basic Formal Ontology (BFO) is a small, upper-level ontology that is designed for use in supporting information retrieval, analysis and integration in scientific and other domains. BFO is a genuine upper ontology. Thus it does not contain physical, chemical, biological or other terms which would properly fall within the coverage domains of the special sciences. BFO is used by more than 130 ontology-driven endeavors throughout the world.
The BFO project was initiated in 2002 under the auspices of the project Forms of Life sponsored by the Volkswagen Foundation. The theory behind BFO was developed first by Barry Smith and Pierre Grenon and presented in a series of publications listed here.
Since then important contributions to BFO have been made by many people, including:
- Mathias Brochhausen
- Werner Ceusters
- Melanie Courtot
- Randall Dipert
- Janna Hastings
- Chris Mungall
- Darren Natale
- Fabian Neuhaus
- James A. Overton
- Bjoern Peters
- Ron Rudnicki
- Alan Ruttenberg
- Stefan Schulz
- Selja Seppälä
- Holger Stenzhorn
- Jie Zheng
... and by more than hundred other members of the BFO Discussion Group.
- Following extensive discussions in the BFO community the decision has been made to release this version as BFO 2.0 OWL. This includes all of the classes defined in the Specification and User's Guide, but only those of the relations for which we have remains authoritative, and is being implemented in the first-order logic version of BFO (BFO 2.0 CLIF). Our plans to incorporate core relations into BFO 2.0 OWL have been postponed to version 2.1, an experimental version of which is available here.
