20.4 IDL Structures Do Not Redefine Logical Information Structures

Go To Top

Return to Phase 0 Implementation Rules and Constraints

An IDL structure realises an FX logical information structure for the selected Phase 0 implementation context.

The IDL structure defines the implementation-level Data representation used by DDS and generated type tooling. It does not redefine the meaning, logical constraints, lineage expectations, governance context, Runtime Plane classification, or Traceability expectations of the FX logical information structure.

The FX logical information structure remains the authoritative logical definition. The IDL structure provides a selected Phase 0 representation.
