Compressed Data within an Internet
Electronic Data Interchange (EDI) Message
Abstract
This document explains the rules and procedures for utilizing
compression (RFC 3274) within an Internet EDI (Electronic Data
Interchange) 'AS' message, as defined in RFCs 3335, 4130, and 4823.

carefully, as they describe your rights and restrictions with respect
to this document.
1. Introduction
Historically, electronic messages produced by systems following the
guidelines as outlined in the IETF EDIINT Working Group
specifications AS1 [AS1], AS2 [AS2], and AS3 [AS3] did not have a way
to provide a standardized transport neutral mechanism for compressing
large payloads. However, with the development of RFC 3274,
"Compressed Data Content Type for Cryptographic Message Syntax
(CMS)", we now have a transport-neutral mechanism for compressing
large payloads.
A typical EDIINT 'AS' message is a multi-layered MIME message,
consisting of one or more of the following: payload layer, signature
layer, and/or encryption layer. When an 'AS' message is received, a
Message Integrity Check (MIC) value must be computed based upon
defined rules within the EDIINT 'AS' RFCs and must be returned to the
sender of the message via a Message Disposition Notification (MDN).
The addition of a new compression layer will require this document to
outline new procedures for building/layering 'AS' messages and
computing a MIC value that is returned in the MDN receipt.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
2. Compressed Data MIME Layer
The compressed-data CMS (Cryptographic Message Syntax) MIME entity as
described in [COMPRESSED-DATA] may encapsulate a MIME entity that
consists of either an unsigned or signed business document.
Implementers are to follow the appropriate specifications identified
in the "MIME Media Types" registry [MIME-TYPES] maintained by IANA
for the type of object being packaged. For example, to package an
XML object, the MIME media type of "application/xml" is used in the
Content-Type MIME header field and the specifications for enveloping
the object are contained in [XMLTYPES].
MIME entity example:
Content-type: application/xml; charset="utf-8"
<?xml version="1.0" encoding="UTF-8"?>
<!-- sample xml document -->

The MIME entity will be compressed using [ZLIB] and placed inside a
CMS compressed-data object as outlined in [COMPRESSED-DATA]. The
