Identity
Identity establishes which enduring thing is being referenced.
Specification-sourced: quoted from the governing specification, pending the applicable specification-owner approvals. The specification controls.
In RSMOne's words
Canonical identity stays durable even when a name, domain type or Capability changes. A regional cooperative stays one identity while being typed as producer and processor, and while acting as supplier in one Formation and buyer in another.
What it is not
Identity ≠ Foundational Kind
Identity says which enduring thing this is; Foundational Kind says what fundamentally different kind of thing it is, and the two are not collapsed into one field. 02 §2.1 · Identity, Kind, Domain Type, and Role
Identity ≠ Contextual Role
Identity endures, while contextual roles change across contexts and over time, so roles are not stored as permanent identity attributes. 02 §9.2 · Context-Bound Roles
