About the Common Core Ontologies
The Common Core Ontologies are a maintained, logically consistent suite of eleven ontologies that supply generic terms and relations for entities found across many domains.
A suite, not a single ontology
The Common Core Ontologies bundle eleven ontologies that each cover a recurring part of reality. They are released together and checked for mutual consistency, so importing one does not contradict another.
- Generic terms that appear across many domains
- A written elucidation for every class and relation
- Open and permissively licensed
Adopted where meaning has to be exact
Both Basic Formal Ontology and the Common Core Ontologies have been directed for use as baseline standards for formal ontology work across the United States defence and intelligence communities, where consistent, well-defined vocabulary is a requirement rather than a nicety.
Read a term, then build on it
Every definition links to the terms it connects to, so you can follow the suite outward from any starting point.
