Notes
Each relationship is represented by a separate row in the relationship file.

Each relationship provides defining information about the source concept.
Change Notice
Since July 2019, OWL axioms the authoritative representation of the stated view of concept definitions are represented by axioms distributed in OWL Expression Reference Sets. Relationships continue to be distributed to represent necessary normal form of the inferred view concept definitions.
