1. Introduction

This document contains the body parts defined in RFC 1495 for

carrying image formats that were originally defined in MIME through

an X.400 system.

It also documents the OIDs assigned to these data formats as FTAM

body parts, which allow the MIME types to be converted to FTAM body

parts; this will probably be more useful than the new body parts

defined here.

2. Newly defined X.400 body parts

2.1. The JPEG body part

The following Extended Body Part is defined for JPEG data streams.

It has no parameters.

jpeg-body-part EXTENDED-BODY-PART-TYPE

DATA OCTET STRING

::= mime-jpeg-body

mime-jpeg-body OBJECT IDENTIFIER ::=

{ mixer-bp-data 3 }

The content is as defined in [MIME].

2.2. The GIF body part

The following Extended Body Part is defined for GIF data streams. It

has no parameters.

gif-body-part EXTENDED-BODY-PART-TYPE

DATA OCTET STRING

::= mime-gif-body

mime-gif-body OBJECT IDENTIFIER ::=

{ mixer-bp-data 4 }

The content is as defined in [MIME].

3. Defined equivalences with MIME types

3.1. image/jpeg - jpeg-body-part

X.400 Body Part: Extended Body Part, OID jpeg-body-part

MIME Content-Type: image/jpeg

Conversion: None

3.2. image/jpeg - FTAM EMA JPEG

X.400 Body Part: FTAM EMA JPEG

MIME Content-Type: image/jpeg

Conversion: None

The OID assigned to JPEG by EMA in [MAWG] is

{ ema objects(2) messaging (2) attachments(1) jpeg-image(6) }

while EMA's OID is

{ joint-iso-ccitt(2) country(16) us(840) organization(1)

ema(113694) }

making the total OID, numeric only

{ 2 16 840 1 113694 2 2 1 6 }

3.3. image/gif - gif-body-part

X.400 Body Part: Extended Body Part, OID gif-body-part

MIME Content-Type: image/gif

Conversion: None

3.4. image/gif - FTAM E...
