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

===== Statement =====

The Conceptual Architecture SHALL define [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Node]], [[dido:99_annexes:annex-b-terms-and-definitions:n:node_identity|Node Identity]], [[dido:99_annexes:annex-b-terms-and-definitions:n:node_role|Node Role]], [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Plane]], [[dido:99_annexes:annex-b-terms-and-definitions:c:communication_endpoint|Communication Endpoint]], [[dido:99_annexes:annex-b-terms-and-definitions:d:data_structure_definition|Data Structure Definition]], [[dido:99_annexes:annex-b-terms-and-definitions:d:data_structure_instance|Data Structure Instance]], [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]], and [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] as core conceptual elements.

===== Source =====

Part 1, Section 13.4: Core Conceptual Element Requirements.

===== Rationale =====

The Conceptual Architecture requires a defined set of core conceptual elements to establish a stable vocabulary for the Financial Systems Archetype. These elements provide the basis for describing distributed participants, identities, responsibilities, runtime purposes, information exchange, information structures, evidence, and traceability.

Defining these elements at the conceptual level supports consistent interpretation across logical models, implementation profiles, deployment profiles, and verification material.

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

This requirement applies to the definition, interpretation, review, and maintenance of core conceptual elements within the Conceptual Architecture.

It applies specifically to:

  * Node
  * Node Identity
  * Node Role
  * Runtime Plane
  * Communication Endpoint
  * Data Structure Definition
  * Data Structure Instance
  * Evidence
  * Traceability

===== Verification =====

Verification SHALL confirm that the Conceptual Architecture defines the required core conceptual elements.

Verification activities include review checks confirming that:

  * Each core conceptual element has a clear definition
  * Each definition supports conceptual interpretation
  * Core conceptual elements remain distinct from implementation and deployment artifacts
  * Later parts reference the core conceptual elements without redefining them
