====== 17.3 Implementation Versioning ======

[[fxdemo:04-part:17-phase-0-implementation-governance:start | Go To Phase 0 Implementation Governance ]]

Phase 0 implementation versioning identifies the versions of implementation artifacts, generated artifacts, configuration artifacts, mappings, scripts, and handbook rules that belong to the Phase 0 implementation baseline.

Implementation versioning applies to:

  - Source files
  - IDL files
  - Generated types
  - DDS Topic mappings
  - QoS profiles
  - Configuration files
  - Scripts
  - Repository structure
  - [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] records
  - Developer Handbook versions
  - Implementation profile revisions

Versioning must allow reviewers to determine which implementation artifact version realized which Part 3 FX logical element at a given point in the Phase 0 baseline.

Implementation versioning also supports compatibility review. A publisher, subscriber, IDL structure, generated type, DDS Topic, QoS profile, and consuming implementation module must align on compatible versions before the interaction can become part of the implementation baseline.
