8.8 FX Cash-Flow Computation Node Mapping
Go To Mapping from FX Logical Nodes to Implementation Artifacts
The FX Cash-Flow Computation Node maps to the Phase 0 implementation artifact that computes projected or derived FX cash-flow obligations from FX Contract State and related context.
The implementation artifact performs the Cash-Flow Computation Role. It consumes FX Contract State and related semantic or transaction context, applies the selected Phase 0 computation approach, produces an implementation representation of FX Cash-Flow Obligation, and publishes that obligation through the DDS Topic that realizes the FX Cash-Flow Obligation Endpoint.
Table 8-6: FX Cash-Flow Computation Node implementation mapping.
| Mapping Concern | Phase 0 Implementation Treatment |
|---|---|
| FX logical Node | FX Cash-Flow Computation Node |
| Primary Node Role | Cash-Flow Computation Role |
| Primary Runtime Plane | FX Logical Data Plane |
| Supporting Runtime Planes | FX Logical Audit and Provenance Plane |
| Primary implementation responsibility | Compute projected or derived FX cash-flow obligations. |
| Primary DDS interactions | Subscribe to the DDS Topic that realizes the FX Contract State Endpoint; publish to the DDS Topic that realizes the FX Cash-Flow Obligation Endpoint. |
| Primary data artifacts | IDL and generated types representing the FX Contract State and the FX Cash-Flow Obligation. |
| Supporting artifacts | Computation helper module, model or calculation configuration, logging helper, and traceability metadata. |
| Traceability expectation | Implementation artifact traces to the FX Cash-Flow Computation Node, Cash-Flow Computation Role, FX Contract State Endpoint, FX Cash-Flow Obligation Endpoint, and FX Cash-Flow Obligation. |
