Users of Common Core Ontologies

The Common Core Ontologies are used and extended by research groups, government programs, and applied projects across domains including manufacturing, aerospace, cybersecurity, earth science, and digital engineering. This page highlights ontologies and ontology-based systems that demonstrate how CCO is applied in practice, including projects that extend CCO, reuse its modules, or adopt its modeling framework within operational workflows.

Together, these examples illustrate how CCO supports semantic interoperability, structured data integration, and ontology-driven analysis across diverse application areas.
