====== 9.4 FX Transaction Intake Topic Mapping ======

[[fxdemo:04-part:09-mapping-from-fx-logical-communication-endpoints-to-dds-topics:start | Go To Mapping from FX Logical Communication Endpoints to DDS Topics ]]

The FX Transaction Intake [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Endpoint]] maps to the [[dido:99_annexes:annex-b-terms-and-definitions:d:dds|DDS]] Topic that carries the Phase 0 implementation representation of FX Transaction Candidate information.

^ Mapping Concern ^ Phase 0 Implementation Treatment ^
| FX logical Communication Endpoint | FX Transaction Intake Endpoint |
| DDS Topic | Data.FX.TransactionCandidate |
| Primary information structure | FX Transaction Candidate |
| IDL structure / generated type | Phase 0 representation of the FX Transaction Candidate |
| Producing Node Role | Transaction Intake Role |
| Consuming Node Roles | Structural Validation Role; Audit Recording Role; Provenance Recording Role |
| Primary Runtime Plane | FX Logical Data Plane |
| Supporting Runtime Plane | FX Logical Audit and Provenance Plane |
| QoS profile family | Data Plane QoS profile |
| Traceability expectation | DDS Topic traces to the FX Transaction Intake Endpoint and the FX Transaction Candidate. |
