Ontology specification guidelineOntology specification guideline

Concepts and instances may have properties with constant values, such as numbers (e.g. 5), strings (e.g. “yes”), or instances. The value cannot be another concept.

Whenever possible, it is recommended to use instances rather than strings, to represent knowledge in the object ontology.

Concept names are in black.Instance names are in blue.
