This part of ISO 8459 specifies and describes the data elements required in the interchange of data between interlending insti-tutions. It also identifies messages and their data elements which are used in interloan transactions.
It is intended for messages communicated both by preprinted forms having the specified data element names as headings and by automated interchange processes.
The structuring of the data elements into messages falls out-side the scope of this part of ISO 8459.
