Domain Identity

Domain Identity defines the stable reference frame of an RDomain: identifier, human-readable naming, version discipline, ownership, lineage and lifecycle state.

Identity Objective

Uniqueness

Primary Key

Domain ID

Governance Anchor

Owner

Operational Control

Lifecycle State

Identity Composition Graph

Each domain identity is a composite record, not only a name string.

Lifecycle State Graph

Lifecycle transitions determine what the domain is allowed to do operationally.

Required Identity Fields

Field	Purpose	Example interpretation
domain_id	Stable machine identity, globally unique in the Athena domain registry.	Used in references, APIs and interoperability checks.
canonical_name	Human-recognizable label for the domain.	Used in UI, documentation and governance records.
semantic_version	Tracks structural change and compatibility class.	Minor for additive change; major for incompatible change.
owner	Steward accountable for quality and evolution.	Defines approval authority and escalation path.
lifecycle_state	Operational status and eligibility for use.	Controls whether domain may be queried or extended.
lineage	Parentage, derivation and succession information.	Preserves historical continuity and merge/split history.

Identity must remain stable across internal revisions. Version changes should update the version field, not mutate the domain identifier.
