[[dido:99_annexes:annex-d-requirements:part-02:start| Return to Requirements]]

===== Statement =====

The Logical Architecture / PIM SHALL define a distributed, node-based logical architecture that conforms to the Part 1 Conceptual Architecture.

===== Source =====

Part 2, Section 16.2: Distributed Node-Based Architecture Requirements.

===== Rationale =====

The Logical Architecture / PIM provides the platform-independent logical realization of the Part 1 Conceptual Architecture. Defining a distributed, node-based logical architecture establishes a common logical foundation for all subsequent Domain Logical Profiles, Implementation Profiles, deployment models, and evidence plans.

Without a defined logical architecture, different implementations could interpret the conceptual architecture differently, reducing interoperability, reviewability, governance, and traceability.

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

This requirement applies to the definition, review, maintenance, interpretation, and evolution of the Part 2 Logical Architecture / PIM.

It applies specifically to:

  * The overall organization of the Logical Architecture;
  * Logical architectural modeling;
  * Domain Logical Profiles derived from Part 2; and
  * Implementation Profiles that realize the Logical Architecture.

===== Verification =====

Verification SHALL confirm that the Logical Architecture / PIM defines a distributed, node-based logical architecture that conforms to the Part 1 Conceptual Architecture.

Verification activities should include review checks confirming that:

  * the architecture is explicitly defined as distributed;
  * logical Nodes form the basis of the architecture;
  * the logical architecture preserves the conceptual meaning established by Part 1; and
  * no conflicting logical architecture is defined within Part 2.

===== Traceability =====

This requirement supports traceability from the Part 1 Conceptual Architecture to the platform-independent Logical Architecture / PIM.
