Return to Requirements

The Phase 0 Implementation Profile / PSM SHALL define Data Plane realization for FX transaction, validation, semantic, contract state, and cash-flow information exchange.

Part 4, Section 21.7: Runtime Plane Realization Requirements.

The Data Plane carries the structured FX information needed to demonstrate the Phase 0 processing path.

Defining a Data Plane realization ensures that transaction, validation, semantic, contract state, and cash-flow information exchanges have an explicit implementation mapping while preserving their logical meaning.

This requirement applies to:

• Data Plane DDS Topics;
• transaction information;
• validation information;
• semantic information;
• contract state information;
• cash-flow information; and
• applicable publishers and subscribers.

Verification SHALL confirm that the Phase 0 Implementation Profile / PSM defines a Data Plane realization for the specified FX information exchanges.

Verification activities should include review checks confirming that:

• applicable Data Plane Topics are identified;
• applicable information structures are mapped;
• producing and consuming participants are identified;
• Data Plane exchanges support the Phase 0 processing path; and
• Data Plane concerns remain distinct from other Runtime Plane concerns.

This requirement establishes the Phase 0 realization of the FX Logical Data Plane.
