1. Introduction

1.1.  What is this document

   This document is informational in nature and attempts to answer
   frequently asked questions concerning the use of the Internet for
   Electronic Data Interchange (EDI).  The primary audience is the EDI
   community that is unfamiliar with the Internet, including software
   developers, users, and service providers.   The reader needs some
   understanding of EDI.  Informational RFCs are prepared by the
   Internet Engineering Task Force (IETF) to improve understanding and
   effectiveness in the use of the Internet.

1.2.  What do you mean by electronic data interchange (EDI) ?

   Except as noted, the document refers to EDI as the use of the

        1) X12 standard developed by the ANSI Accredited Standards
           Committee X12 or

        2) EDIFACT[1] standard United Nations Economic Commission for
           Europe (UN/ECE), Working Party for the Facilitation of
           International Trade Procedures (WP.4).

   The differences between these standards is beyond the scope of this
   FAQ.  Both standards activities are managed in the US by:

                Data Interchange Standards Association, Inc,
                1800 Diagonal Road, Suite 200
                Alexandria, Virginia, 22314-2852
                Voice: 703-548-7005
                FAX: [phone]

   There are numerous other standards one could use for EDI, but
   discussion of them is not in the scope of this document.

1.3.  What are the X12 Standards that I should be aware of ?

   ACCREDITED STANDARDS COMMITTEE (ASC) X12 Standards are available from
   DISA at the address specified in Question 1.  The following is a good
   starting set of X12 standards.

           Data Interchange, DISA 1994 Publications Catalog

       6.  ASC X12.58 Security Structures

1.4.  To whom do I send comments and suggestions ?

   Readers are invited to add questions; please include an answer if you
   know or want to suggest one.  Of course corrections and comments are
   welcome; send them to the IETF-EDI mail list by subscribing as
   described in question 7.6.  Or a send your comment to
   [e-mail].

1.5.  How can I get a copy of this document?

   Request for Comments documents (RFC) are available by anonymous FTP.
   Login with the username "anonymous" and a password of your e-mail
   address.  After logging in, type "cd rfc" and then

        "get rfc1865.txt".

   A Web address for the RFC is:

      ftp://ds.internic.net/rfc/rfc1865.txt

   RFC directories are located at:

        o  Africa at:        ftp.is.co.za    (196.4.160.2)
        o  Europe:           nic.nordu.net   (192.36.148.17)
        o  Pacific Rim:      munnari.oz.au   (128.250.1.21)
        o  US East Coast:    ds.internic.net (198.49.45.10)
        o  US West Coast:    ftp.isi.edu     (128.9.0.32)

   RFCs are also available by mail.  Send a message to:
   [e-mail]. In the body type:

        "FILE /rfc/rfc1865.txt"

   NOTE: The mail server at ds.internic.net can return the document in
   MIME-encoded form by using the "mpack" utility.  To use this feature,
   insert the command "ENCODING mime" before the "FILE" command.  To
   decode the response(s), you will need "munpack" or a MIME-compliant
   mail reader.  Different MIME-compliant mail readers exhibit different
   behavior, especially when dealing with "multipart" MIME messages
   (i.e., documents which have been split up into multiple messages), so
   check your local documentation on how to manipulate these messages.
