3.5 Traceability Position

Go To Top

This part uses the following Traceability position.

SIP-RA provides the parent with a structured information processing discipline. FDIS-RA provides financial-domain interpretation alignment. Part 1 provides the conceptual foundation. The original FX Demo Reference Architecture provides source material that this part normalizes into a distributed, node-based Logical Architecture / PIM.

This traceability position prevents three kinds of confusion.

First, it prevents the Logical Architecture / PIM from replacing the Part 1 Conceptual Architecture. Second, it prevents the original FX Demo Reference Architecture from remaining a mixed-layer controlling document. Third, it prevents implementation mechanisms such as DDS, REST, RPC, Protocol Buffers, IDL, Python, Kubernetes, K3S, Docker, RTI Connext DDS, or Crucible from defining the logical architecture.

Part 2 defines one platform-independent, distributed, node-based logical architecture. Later parts specialize, implement, deploy, test, and evidence the Logical Architecture while preserving Traceability back to Part 1.
