ISO 20022-5:2013 defines a scalable, methodical process for reverse engineering existing financial industry message sets into ISO 20022-compliant BusinessTransactions and MessageSets. It covers gap analysis, development of required ISO 20022 updates, registration with the ISO 20022 Registration Authority, convergence and coexistence documentation, and migration planning.
The standard explains how to compare industry messages with ISO 20022 business processes, transactions, message definitions, business roles, business components, message components, and data types. It also describes convergence tables for data types, elements, messages, and message items, supporting systematic mapping and potential automation of migration activities.
This first edition cancels and replaces ISO/TS 20022-5:2004 and is intended for financial services organizations, standards developers, messaging architects, and teams planning migration from existing industry message sets to ISO 20022.
Application Scope: Financial services messaging, ISO 20022 implementation, legacy message-set analysis, message mapping, interoperability, registration, and migration planning.
