The [[dido:99_annexes:annex-b-terms-and-definitions:f:foreign_exchange_domain|Foreign Exchange Domain]] provides the initial domain profile for the Financial Systems [[dido:99_annexes:annex-b-terms-and-definitions:a:archetype|Archetype]]. Foreign Exchange systems exchange structured information about transactions, currency pairs, counterparties, lifecycle states, validation results, semantic interpretations, contractual [[dido:99_annexes:annex-b-terms-and-definitions:o:obligation|obligations]], projected cash flows, release decisions, audit records, provenance records, and oversight views.

[[fxdemo:01-part:start]] defines the conceptual foundation for the Financial Systems Archetype. [[fxdemo:02-part:start]] defines a distributed, node-based Logical Architecture / [[dido:99_annexes:annex-b-terms-and-definitions:p:platform_independent_model|PIM]]. This part builds outward from those foundations by specializing the Part 2 logical architecture for the FX Demo.

The FX Demo Logical Profile identifies the FX-specific logical [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Nodes]], logical [[dido:99_annexes:annex-b-terms-and-definitions:n:node_role|Node Roles]], logical [[dido:99_annexes:annex-b-terms-and-definitions:c:communication_endpoint|Communication Endpoints]], logical information structures, logical Runtime Planes, logical interaction patterns, logical governance relationships, and logical traceability relationships needed to demonstrate the distributed, node-based architecture in the Foreign Exchange Domain.

This part remains platform-independent. It defines FX logical structures and relationships, with later parts selecting implementation technologies, data serialisation formats, communication mechanisms, programming languages, deployment topologies, runtime packaging, test mechanisms, and evidence-capture mechanisms.

The FX Demo Logical Profile supports later implementation and deployment work by identifying the logical responsibilities and information flows that [[fxdemo:04-part:start]] map to implementation artifacts and [[fxdemo:05-part:start]] to deploy, test, observe, and evidence.
