3. Traceability to Parent and Source Architectures

Go to Top

The Financial Systems Archetype preserves Traceability to three architectural sources.

First, it traces to SIP-RA as the parent structured-information processing Reference Architecture (RA). SIP-RA provides the cross-domain discipline for structured information processing, including separation of Data, Structure, Semantics, Interpretation, Governance and Authority, and implementation-independent processing.

Second, it aligns with FDIS-RA as a financial-domain interpretation architecture. FDIS-RA provides precedent for treating semantic Interpretation, validation, comparability, Traceability, auditability, and Evidence as architectural concerns in financial and regulated reporting environments.

Third, it normalises source material from the original FX Demo Reference Architecture. The original FX Demo Reference Architecture (RA) combined conceptual definitions, logical architecture, DDS-oriented implementation concerns, Quality of Service (QoS), topics, Data Structure Definitions, common data types, ontology concerns, Node Roles, use cases, and catalogues. The Financial Systems Archetype document set separates those concerns into conceptual, logical, profile, implementation, deployment, testability, and Evidence layers.
