draft X.400 image body parts Nov 95
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.
This document is an Experimental standard; if it turns out to be
useful and widely deployed, it can be moved onto the standards
track.
Editor's note
It is trivially easy to define new OIDs for these things as
FTAM body parts. This gives us a much more capable (AND
complex) encapsulation. Group input into this decision is
sought.
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
Alvestrand Expires May 96 [Page 2]
draft X.400 image body parts Nov 95
::= 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/gif - gif-body-part
X.400 Body Part: Extended Body Part, OID gif-body-part
MIME Content-Type: image/gif
Conversion: None
4. Security considerations
Security issues are not consiered in this memo.
