===== Statement =====

The Conceptual Architecture SHALL distinguish among a [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Node]], a [[dido:99_annexes:annex-b-terms-and-definitions:n:node_role|Node Role]], a [[dido:99_annexes:annex-b-terms-and-definitions:n:node_identity|Node Identity]], a [[dido:99_annexes:annex-b-terms-and-definitions:c:communication_endpoint|Communication Endpoint]], a [[dido:99_annexes:annex-b-terms-and-definitions:d:data_structure_definition|Data Structure Definition]], a [[dido:99_annexes:annex-b-terms-and-definitions:d:data_structure_instance|Data Structure Instance]], a [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Plane]], an implementation artifact, and a deployment artifact.

===== Source =====

Part 1, Section 13.4: Core Conceptual Element Requirements.

===== Rationale =====

The core conceptual elements describe different architectural concerns. A Node, Node Role, Node Identity, Communication Endpoint, Data Structure Definition, Data Structure Instance, Runtime Plane, implementation artifact, and deployment artifact each serves a distinct purpose.

Distinguishing these elements prevents identity, responsibility, communication, information, runtime purpose, implementation, and deployment concerns from collapsing into one another.

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

This requirement applies to all uses of core conceptual elements within the Conceptual Architecture.

It applies specifically to distinctions among:

  * Node
  * Node Role
  * Node Identity
  * Communication Endpoint
  * Data Structure Definition
  * Data Structure Instance
  * Runtime Plane
  * Implementation artifact
  * Deployment artifact

===== Verification =====

Verification SHALL confirm that the Conceptual Architecture distinguishes among the named core conceptual, implementation, and deployment elements.

Verification activities include review checks confirming that:

  * Node, Node Role, and Node Identity remain distinct
  * Communication Endpoint remains distinct from Nodes and exchanged information
  * Data Structure Definition remains distinct from Data Structure Instance
  * Runtime Plane remains distinct from implementation and deployment artifacts
  * Implementation artifacts and deployment artifacts do not redefine conceptual elements
