====== SIP-049 — Architectural Concern and Lifecycle Description ======

[[public:00-sip-ra:99-annexes:annex-c-requirements:start|Go to Annex C: Requirements]]

===== Statement =====

The Submission SHALL describe the separation and coordination of [[public:99_annexes:annex-b-terms-and-definitions:d:data|Data]], [[public:99_annexes:annex-b-terms-and-definitions:s:structure|Structure]], [[public:99_annexes:annex-b-terms-and-definitions:s:semantic|Semantics]], and [[public:99_annexes:annex-b-terms-and-definitions:i:interpretation|Interpretation]] and the independent definition, versioning, and lifecycle [[public:99_annexes:annex-b-terms-and-definitions:g:governance|Governance]] of structural, semantic, and interpretive [[public:99_annexes:annex-b-terms-and-definitions:a:artifact|Artifacts]].

===== Rationale =====

Data, Structure, Semantics, and Interpretation perform distinct architectural functions. Treating them as separable concerns allows each to be governed, versioned, changed, and reused without requiring simultaneous changes to the others.

The architectural description must also explain how these concerns remain coordinated. Separation without defined relationships would make it difficult to determine which structural, semantic, and interpretive Artifacts apply to particular Data or processing activities.

===== Evaluation Criteria =====

A conforming Submission demonstrates that:

  - Data, Structure, Semantics, and Interpretation are separately identified
  - The responsibilities assigned to each architectural concern are described
  - Relationships and coordination mechanisms among the concerns are defined
  - Structural Artifacts can be identified and versioned independently
  - Semantic Artifacts can be identified and versioned independently
  - Interpretive Artifacts can be identified and versioned independently
  - Governance authorities and lifecycle controls are identified for each Artifact category
  - Applicability among versions of Data, structural Artifacts, semantic Artifacts, and interpretive Artifacts can be determined
  - Changes to one concern do not silently modify another concern
  - Provenance and traceability among applicable Artifacts are preserved
