Abstract

A previous document, RFC 1341, defines a format and general framework for the representation of a wide variety of data types in Internet mail. This document defines one particular type of MIME data, the matter-transport/sentient-life-form type. The matter- transport/sentient-life-form MIME type is intended to facilitate the wider interoperation of electronic mail messages that include entire sentient life forms, such as human beings.

Abstract

A previous document, RFC 1341, defines a format and general framework

for the representation of a wide variety of data types in Internet

mail. This document defines one particular type of MIME data, the

matter-transport/sentient-life-form type. The matter-

transport/sentient-life-form MIME type is intended to facilitate the

wider interoperation of electronic mail messages that include entire

sentient life forms, such as human beings.

Other informally proposed subtypes, such as "non-sentient-life-form",

"non-sentient-non-life-form", and the orthogonally necessary but

nevertheless puzzling "sentient-non-life-form", are not described in

this memo.

The matter-transport/sentient-life-form MIME type

In order to promote the wider interoperability of life-bearing email,

this document defines a new MIME content-type, "matter-transport",

and for an initial subtype, "sentient-life-form". This subtype was

designed to meet the following criteria:

1. The syntax must be extremely simple to parse, to minimize the

risk of accidental death due to misinterpretation of the standard.

2. The data format must be extremely robust, with redundancy to

ensure that individual life forms will survive and be

reconstituted in such a form as to be nearly indistinguishable

from their initial state, no matter how many bizarre email

gateways are encountered in transit.

3. The syntax must be extensible to allow for the description of

all yet-undiscovered aspects of life forms which will be required

for the transport of non-human species (e.g. dolphins, Klingons,

or politicians).

4. The syntax must be compatible with SGML, so that with an

appropriate DTD (Document Type Definition -- the standard

mechanism for defining a document type using SGML), a general SGML

parser could be written to parse the data structure and produce

directives to a lifeform-reconstitution mechanism. However,

despite this compatibility, the syntax will most likely be far

simpler than that of full SGML (so that no SGML knowledge is

required in order to implement it), since it is anticipated that

the full complexities of SGML will not be necessary for the

description of even arbitrarily complex organic life forms.

The syntax of the new content-type is very simple, and indeed makes
