The primary syntax for ISO 20022 messages is XML. To avoid LibEuFin clients having to deal with XML, we define a mapping from ISO 20022 messages into JSON. The specifics of this mapping are: - * The JSON should be "idiomatic" and easy to process - * When possible, the highly nested structures of ISO 20022 should be flattened + * The JSON should be "idiomatic" and easy to process. + * When possible, the highly nested structures of ISO 20022 should be flattened. * It must be possible round-trip between the LibEuFin JSON and ISO 20022 XML messages.

An example for this is how the Swiss and EPC interpretations handle transaction amounts in the presence of multiple currencies. @@ -209,4 +209,3 @@ FIXME: This is not complete yet. proprietaryIssuer?: string; proprietaryCode?: string; } - |
