Basic Formal Ontology

Basic Formal Ontology (BFO) is a framework that helps organize and categorize concepts and things in the world in a consistent way. It provides a structured vocabulary to describe different types of entities—such as physical objects, processes, or qualities—and their relationships. BFO is used mainly in knowledge representation and data sharing across fields like biology, medicine, and information science, ensuring everyone uses common definitions. Essentially, BFO helps make knowledge clearer and more interoperable by establishing fundamental principles for understanding and modeling the structure of reality.
