Abstract

The Multipart/Related content-type provides a common mechanism for

representing objects that are aggregates of related MIME body parts.

This document defines the Multipart/Related content-type and provides

examples of its use.

1. Introduction

Several applications of MIME, including MIME-PEM, and MIME-Macintosh

and other proposals, require multiple body parts that make sense only

in the aggregate. The present approach to these compound objects has

been to define specific multipart subtypes for each new object. In

keeping with the MIME philosophy of having one mechanism to achieve

the same goal for different purposes, this document describes a

single mechanism for such aggregate or compound objects.

The Multipart/Related content-type addresses the MIME representation

of compound objects. The object is categorized by a "type"

parameter. Additional parameters are provided to indicate a specific

starting body part or root and auxiliary information which may be

required when unpacking or processing the object.

Multipart/Related MIME entities may contain Content-Disposition

headers that provide suggestions for the storage and display of a

body part. Multipart/Related processing takes precedence over

Content-Disposition; the interaction between them is discussed in

section 4.

Responsibility for the display or processing of a Multipart/Related's

constituent entities rests with the application that handles the

compound object.
