Return to Requirements

Each IDL and generated type mapping SHALL preserve traceability to the Part 3 FX logical information structure.

Part 4, Section 21.6: Information Structure Mapping Requirements.

IDL structures and generated types are implementation representations of logical information definitions and must remain connected to those authoritative Part 3 sources.

Preserving traceability allows reviewers to determine why each implementation representation exists and whether it remains consistent with the intended logical meaning.

This requirement applies to:

• IDL structures;
• generated types;
• FX logical information structures;
• mapping metadata; and
• implementation traceability records.

Verification SHALL confirm that each IDL and generated type mapping preserves traceability to its applicable Part 3 FX logical information structure.

Verification activities should include review checks confirming that:

• the applicable logical information structure is identifiable;
• mapping records connect IDL and generated types to that source;
• changes preserve or explicitly update the traceability relationship; and
• reviewers can navigate from implementation representation to Part 3 definition.

This requirement establishes backward traceability from Phase 0 information representations to their authoritative Part 3 FX logical information structures.
