===== Five Architectural Concerns =====

  * **Data** — the values, observations, and assertions being processed
  * **Structure** — how Data is organized, identified, related, and constrained
  * **Semantics** — what the Data and structural elements mean within a defined context
  * **Interpretation** — the rules, calculations, classifications, and reasoning applied to the Data
  * **Governance** — the Authority to define, approve, change, and apply the other concerns

===== Why Separation Matters =====

  * Each concern can be governed and versioned independently
  * Relationships among the concerns remain explicit and traceable
  * Changes can be evaluated before they affect operational outcomes
  * Different technologies can implement the same governed models
  * Independently governed Domains can cooperate without surrendering Authority

===== Two Related Flows =====

  * **Operational information flow** carries Data among participating Systems
  * **Governance control** manages the Structures, Semantics, rules, Policies, and Authorities applied to that Data

**NOTE: SIP-RA makes the relationships explicit without requiring a single implementation, platform, or governing Authority.**
