IOF Ontology Browser
The Industrial Ontology Foundry (IOF) is a unit of OAGi (Open Applications Group), a non-profit with the mission to reduce integration costs through interoperable, cross-functional standards for digital manufacturing.
IOF publishes a suite of OWL ontologies built on the Basic Formal Ontology (BFO). This browser exposes every class, its annotations, and formal axioms — organized by domain.
