[[dido:99_annexes:annex-d-requirements:part-04:start| Return to Requirements]]

===== Statement =====

Implementation governance SHALL define implementation versioning.

===== Source =====

Part 4, Section 21.13: Implementation Governance Requirements.

===== Rationale =====

Implementation versioning allows reviewers to determine which versions of source files, generated artifacts, mappings, configuration, scripts, and handbook rules belong to a particular Phase 0 baseline.

Versioning also supports compatibility review among DDS Topics, IDL structures, generated types, QoS profiles, and implementation participants.

===== Applies To =====

This requirement applies to:

  * source files;
  * IDL structures and generated types;
  * DDS Topic mappings;
  * QoS profiles;
  * configuration artifacts; and
  * scripts and handbook revisions.

===== Verification =====

Verification SHALL confirm that implementation governance defines implementation versioning.

Verification activities should include review checks confirming that:

  * governed artifact versions are identifiable;
  * baseline versions can be determined;
  * version relationships among dependent artifacts are reviewable; and
  * version changes follow implementation governance.

===== Traceability =====

This requirement establishes version control for artifacts belonging to the Phase 0 implementation baseline.
