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

===== Statement =====

Each interaction realization SHALL identify the implementation participants involved.

===== Source =====

Part 4, Section 21.8: Interaction Pattern Realization Requirements.

===== Rationale =====

Identifying participating implementation artifacts makes the allocation of responsibilities within each realized interaction explicit.

This allows reviewers to determine which Phase 0 participants perform the producing, consuming, processing, control, observation, or supporting responsibilities required by the interaction.

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

This requirement applies to:

  * implementation participants;
  * runtime participants;
  * implementation node modules; and
  * interaction mapping records.

===== Verification =====

Verification SHALL confirm that each interaction realization identifies all implementation participants involved.

Verification activities should include review checks confirming that:

  * producing participants are identified;
  * consuming participants are identified;
  * intermediate or supporting participants are identified where applicable; and
  * each participant maps to an applicable logical responsibility.

===== Traceability =====

This requirement connects Phase 0 interaction realizations to the implementation participants that perform the applicable logical responsibilities.
