Description / Abstract:


One of the key requirements before organisations can exchange administrative, commercial and transport information between their computers, without manual intervention, is agreement on the content and structure of the information to be transmitted.

In EDIFACT, this is achieved by developing United Nations Standard Electronic Messages (UNSM's), for both national and international use.

These guidelines are intended for:-

- those who want to submit a draft message for registration as a new UNSM. To achieve this status : -

- the proposed draft message must be for use at the international level (rather than solely for use at a National or Sectoral level

-there must be no existing UNSM having a function identical (or nearly identical) with the proposed draft

- the proposers of the draft need to accept that if there is interest in the proposed message amongst other potential users in other sectors and/or countries, those users will wish to take part in and contribute to the development

- those who wish to propose an amendment to an existing UNSM by means of a "Change Request". (The procedures for maintenance, change requests and technical assessment will be found in Appendix 4 to these guidelines)
