The Model Primary Content Type for Multipurpose Internet Mail Extensions

Status of this Memo

This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.

Introduction

The purpose of this memo is to propose an update to Internet RFC 2045 to include a new primary content-type to be known as "model". RFC 2045 [1] describes mechanisms for specifying and describing the format of Internet Message Bodies via content-type/subtype pairs. We believe that "model" defines a fundamental type of content with unique presentational, hardware, and processing aspects. Various subtypes of this primary type are immediately anticipated but will be covered under separate documents.

RFC 2077 Model Primary MIME Types January 1997

1. Overview

This document will outline what a model is, show examples of models, and discuss the benefits of grouping models together. This document will not directly deal with the intended subtypes since those will be covered by their separate registrations. Some immediately expected subtypes are listed in section 7.

This document is a discussion document for an agreed definition, intended eventually to form a standard accepted extension to RFC 2045. We are also targeting developers of input/output filters, viewer software and hardware, those involved in MIME transport, and decoders.

2. Definition of a model

A model primary MIME type is an electronically exchangeable behavioral or physical representation within a given domain. Each subtype in the model structure has unique features, just as does each subtype in the other primary types. The important fact is that these various subtypes can be converted between each other with less loss of information then to that of other primary types. This fact groups these subtypes together into the model primary type. All of the expected subtypes have several features in common and that are unique to this primary type.

To loosely summarize: models are multidimensional structures composed of one or more objects. If there ar...
