====== 9.6 FX Semantic Interpretation 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 Semantic Interpretation [[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 Semantic Assertion information.

</WRAP>

^ Mapping Concern ^ Phase 0 Implementation Treatment ^
| FX logical Communication Endpoint | FX Semantic Interpretation Endpoint |
| DDS Topic | Data.FX.SemanticAssertion |
| Primary information structure | FX Semantic Assertion |
| IDL structure / generated type | Phase 0 representation of the FX Semantic Assertion |
| Producing Node Role | Semantic Interpretation Role |
| Consuming Node Roles | Contract State Management Role; Policy Evaluation Role; Audit Recording Role; Provenance Recording Role |
| Primary Runtime Plane | FX Logical Data Plane |
| Supporting Runtime Planes | FX Logical Audit and Provenance Plane; FX Logical Policy and Release Plane where semantic classification affects release. |
| QoS profile family | Data Plane QoS profile |
| Traceability expectation | DDS Topic traces to the FX Semantic Interpretation Endpoint and the FX Semantic Assertion. |
