====== 3.5 Traceability Position ====== [[fxdemo:02-part:start | Go To Top ]] This part uses the following [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|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 [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|evidence]] the Logical Architecture while preserving [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] back to Part 1. ---- © 2026 Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
