6. The SIP-RA Architectural Separation

• 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

• 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

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