===== Statement =====

Each IDL and generated type mapping SHALL identify the DDS Topic or Topics that carry the generated type.

===== Source =====

Part 4, Section 21.6: Information Structure Mapping Requirements.

===== Rationale =====

Identifying the DDS Topics that carry a generated type connects the implementation data representation to the communication exchanges in which it participates.

This relationship supports communication review, type compatibility review, and end-to-end traceability from logical information structure through IDL and generated type to runtime exchange.

===== Applies To =====

This requirement applies to:

  * IDL and generated type mappings;
  * DDS Topics;
  * publishers and subscribers; and
  * communication mapping records.

===== Verification =====

Verification SHALL confirm that each IDL and generated type mapping identifies the DDS Topic or Topics that carry the generated type.

Verification activities should include review checks confirming that:

  * applicable DDS Topics are identified;
  * Topic data representations agree with the generated type;
  * Topic mappings agree with the corresponding IDL structure; and
  * incompatible Topic/type relationships are not admitted to the baseline.

===== Traceability =====

This requirement connects Phase 0 generated types to the DDS Topic mappings through which they are exchanged.
