3.3 Traceability to Part 1 Conceptual Architecture

Go To Top

Part 1 defines the conceptual foundation for the Financial Systems Archetype. This part builds outward from that foundation by specialising the concepts from Part 1 into platform-independent logical elements.

This part does not redefine the concepts in Part 1. It gives those concepts logical structure, relationships, responsibilities, constraints, and interaction patterns.

Table 3-3: Part 1 concepts specialised by the Logical Architecture / PIM

Part 1 concept	Part 2: logical treatment
Node	Logical Node
Node Identity	Logical Node Identity
Node Role	Logical Node Role
Runtime Plane	Logical Runtime Plane
Communication Endpoint	Logical Communication Endpoint
Data Structure Definition	Logical Data Structure Definition
Data Structure Instance	Logical Data Structure Instance
Evidence	Logical evidence expectation or logical evidence class
Traceability	Logical traceability relationship
Classification Path	Logical scope inherited by profiles and logical models
Separation of Concerns	Logical separation of runtime, information, governance, traceability, and evidence concerns

The Traceability from Part 1 to Part 2 allows reviewers to confirm that the Logical Architecture / PIM preserves the conceptual foundation while adding logical specificity.
