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

===== Statement =====

The Conceptual Architecture SHALL distinguish a [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Node]] as an architectural participant in a distributed [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_system|Financial System]].

===== Source =====

Part 1, Section 13.4: Core Conceptual Element Requirements.

===== Rationale =====

A Node represents an architectural participant in a distributed Financial System. Distinguishing a Node at the conceptual level prevents confusion between an architectural participant and implementation-specific artifacts such as processes, containers, services, executables, or deployment units.

This requirement preserves the conceptual role of a Node across logical, implementation, and deployment refinement.

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

This requirement applies to all references to Nodes within the Conceptual Architecture.

It applies specifically to:

  * Architectural participants
  * Distributed Financial System participants
  * Node definitions
  * Node descriptions
  * Node-related conceptual diagrams

===== Verification =====

Verification SHALL confirm that the Conceptual Architecture distinguishes a Node as an architectural participant in a distributed Financial System.

Verification activities include review checks confirming that:

  * Node references identify architectural participants
  * Node references do not depend on implementation technology
  * Node references do not substitute for containers, processes, or services
  * Later profiles map implementation artifacts to Nodes without redefining Node meaning
