9.2 Topic Mapping Principles

Go To Mapping from FX Logical Communication Endpoints to DDS Topics

The Phase 0 Implementation Profile applies the following principles when mapping FX logical Communication Endpoints to DDS Topics.

Each DDS Topic mapping identifies:

• the FX logical Communication Endpoint it realizes;
• the FX logical information structure carried by the endpoint;
• the IDL structure and generated type used for the Phase 0 exchange;
• the producing FX logical Node or Node Role;
• the consuming FX logical Node or Node Role;
• the Runtime Plane or Runtime Planes associated with the exchange;
• the Quality of Service (QoS) profile or QoS profile family used for the Topic;
• the applicable governance, versioning, and compatibility expectations; and
• the traceability relationship back to the Part 3 FX logical Communication Endpoint.

The mapping does not require every future endpoint to exist in Phase 0. Phase 0 maps only the selected endpoints needed for the implementation baseline.
