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

===== Statement =====

A [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node_identity|Logical Node Identity]] SHALL uniquely distinguish a [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Logical Node]] within the Logical Architecture / PIM.

===== Source =====

Part 2, Section 16.3: Logical Node Requirements.

===== Rationale =====

Logical Node Identity provides the basis for uniquely identifying Logical Nodes within the Logical Architecture / PIM. Unique identification supports communication, governance, traceability, compatibility assessment, operational review, and implementation mapping.

Without unique identities, logical interactions and responsibilities could not be unambiguously attributed to individual Logical Nodes.

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

This requirement applies to the definition, maintenance, interpretation, and use of Logical Node Identities.

It applies specifically to:

  * Logical Node identification;
  * Logical interaction modeling;
  * Governance relationships;
  * Traceability relationships; and
  * Implementation mappings.

===== Verification =====

Verification SHALL confirm that each Logical Node can be uniquely distinguished by its Logical Node Identity.

Verification activities should include review checks confirming that:

  * each Logical Node has a unique Logical Node Identity;
  * identities distinguish Logical Nodes within the Logical Architecture;
  * Logical Node Identities support traceability and governance; and
  * implementation mappings preserve Logical Node Identity.

===== Traceability =====

This requirement supports traceability between Logical Node Identity and the Logical Nodes identified within the Logical Architecture.
