====== P1-REQ-13-5-007 ======

[[dido:99_annexes:annex-d-requirements:part-01:start|Return to Part 1 Requirements]]

===== Statement =====

The Conceptual Architecture SHALL distinguish [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Planes]] from implementation mechanisms.

===== Source =====

Part 1, Section 13.5: Runtime Plane Requirements.

===== Rationale =====

Runtime Planes classify runtime communication and behavior by architectural purpose. Implementation mechanisms realize selected aspects of those planes in a particular technology environment.

Distinguishing Runtime Planes from implementation mechanisms prevents DDS topics, middleware constructs, APIs, services, scripts, generated types, containers, or other mechanisms from redefining the conceptual plane.

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

This requirement applies to all Runtime Plane definitions and references within the Conceptual Architecture.

It applies specifically to distinctions between Runtime Planes and:

  * Middleware mechanisms
  * DDS mechanisms
  * APIs
  * Services
  * Scripts
  * Generated types
  * Containers
  * Deployment tooling

===== Verification =====

Verification SHALL confirm that the Conceptual Architecture distinguishes Runtime Planes from implementation mechanisms.

Verification activities include review checks confirming that:

  * Runtime Planes classify architectural purpose
  * Implementation mechanisms realize Runtime Planes without redefining them
  * Technology examples do not become conceptual plane definitions
  * Later profiles preserve the conceptual meaning of each Runtime Plane
