scope:

ISO 11649 specifies the elements of a structured creditor reference (RF Creditor Reference) used to facilitate the processing of data in data interchange, in the financial services as well as between other business domains. The RF Creditor Reference is designed for use in an automated processing environment, but can also be implemented in other media interchanges (e.g. paper document exchange, etc.).
ISO 11649 does not specify internal procedures, file organization techniques, storage media, languages, etc.
to be used in its implementation. It is applicable only to the textual data which may be conveyed through a system (network).
