ISO 20022 is an ISO standard for electronic data interchange between financial institutions. It describes a metadata repository containing descriptions of messages and business processes, and a maintenance process for the repository content. The standard covers financial information transferred between financial institutions that includes payment transactions, securities trading and settlement information, credit and debit card transactions and other financial information.
The repository contains a huge amount of financial services metadata that has been shared and standardized across the industry. The metadata is stored in UML models with a special ISO 20022 UML Profile. Underlying all of this is the ISO 20022 metamodel - a model of the models. The UML profile is the metamodel transformed into UML. The metadata is transformed into the syntax of messages used in financial networks. The first syntax supported for messages was XML Schema.
ISO 20022 will be widely used in financial services, tentatively starting in March 2023. Despite many misinformation of the contrary, compliance on this standard is not measured or granted by a regulatory body: "There is no official certification authority for ISO 20022, and the implementation of ISO 20022 message definitions will depend a lot on the specific requirements of the community that is implementing."
ISO 20022 is widely used in financial services. Organizations participating in ISO 20022 include: SWIFT, XRP, Algorand, XLM, XEP, and IOTA.
ISO 20022 is the successor to ISO 15022; originally ISO 20022 was called ISO 15022 2nd Edition. ISO 15022 was the successor of ISO 7775.
