Definition: The Pan-European Request Orchestration ABB is an Application Service that coordinates the sequence of cross-border interoperability steps (identification, request, retrieval, routing) required to fulfil a pan-European health-data access transaction, managing state and error handling across the workflow.

Interoperability Saliency: Salient for technical interoperability because it provides the coordinating control-flow layer that ties together the individual pan-European access-enabler ABBs into a coherent transaction.
