====== P1-REQ-13-9-001 ======

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

===== Statement =====

The [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_model|Logical Architecture]] / [[dido:99_annexes:annex-b-terms-and-definitions:p:platform_independent_model|PIM]] SHALL use the conceptual elements defined in this part.

===== Source =====

Part 1, Section 13.9: Relationship to Logical Architecture / PIM Requirements.

===== Rationale =====

The Logical Architecture / PIM refines the Conceptual Architecture. Using the conceptual elements defined in this part preserves the relationship between conceptual meaning and logical structure.

This requirement prevents the Logical Architecture / PIM from introducing a separate conceptual vocabulary that competes with, bypasses, or obscures the Conceptual Architecture.

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

This requirement applies to Logical Architecture / PIM elements that refine, specialize, constrain, or relate to the Conceptual Architecture.

It applies specifically to:

  * Logical elements
  * PIM elements
  * Conceptual element references
  * Logical refinement
  * Cross-part consistency

===== Verification =====

Verification SHALL confirm that the Logical Architecture / PIM uses the conceptual elements defined in this part.

Verification activities include review checks confirming that:

  * Logical elements reference relevant conceptual elements
  * PIM elements use the conceptual vocabulary defined in Part 1
  * Logical refinement preserves conceptual meaning
  * Logical material does not introduce competing conceptual definitions
