====== P4-REQ-21-15-003 ======

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

===== Statement =====

The Part 5 handoff SHALL identify DDS Topic mappings.

===== Source =====

Part 4, Section 21.15: Part 5 Handoff Requirements.

===== Rationale =====

Part 5 uses the communication mappings defined by Part 4 when deploying, exercising, observing, and testing Phase 0 implementation participants.

Including DDS Topic mappings in the handoff ensures that runtime exchanges remain tied to their FX logical Communication Endpoints.

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

This requirement applies to:

  * DDS Topics;
  * Communication Endpoint mappings;
  * publishers;
  * subscribers; and
  * applicable communication configuration.

===== Verification =====

Verification SHALL confirm that the Part 5 handoff identifies the DDS Topic mappings required by the selected Phase 0 baseline.

Verification activities should include review checks confirming that:

  * applicable DDS Topics are identified;
  * producing and consuming participants are identifiable;
  * logical Communication Endpoint mappings are preserved; and
  * Topic mappings are suitable for Part 5 deployment and test planning.

===== Traceability =====

This requirement carries the Part 4 Communication Endpoint-to-DDS Topic mappings into the Part 5 handoff.
