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

===== Statement =====

The Logical Architecture / PIM SHALL organize the architecture around identifiable [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Logical Nodes]].

===== Source =====

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

===== Rationale =====

Logical Nodes provide the primary organizing concept for the Logical Architecture. Identifiable Logical Nodes establish clear responsibilities, communication relationships, governance boundaries, traceability, and reviewability while remaining independent of implementation technology.

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

This requirement applies to the Logical Architecture / PIM and all Domain Logical Profiles that specialize it.

It applies specifically to:

  * Logical architectural modeling;
  * Identification of Logical Nodes;
  * Assignment of logical responsibilities; and
  * Logical interaction modeling.

===== Verification =====

Verification SHALL confirm that the Logical Architecture is organized around identifiable Logical Nodes.

Verification activities should include review checks confirming that:

  * Logical Nodes are explicitly identified;
  * logical interactions occur among Logical Nodes;
  * logical responsibilities are assigned to Logical Nodes; and
  * the architecture consistently uses Logical Nodes as the primary organizational element.

===== Traceability =====

This requirement supports traceability from conceptual Nodes defined in Part 1 to Logical Nodes defined in Part 2.
