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 is widely used in financial services. Organizations participating in ISO 20022 include SWIFT. 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.
