Content-Type: text/plain; charset=us-ascii Date: Tue, 20 Aug 1996 13:09:32 +0200 Sender: [email protected] Content-Length: 4240 Status: RO X-Lines: 80 Jon and Joyce, did you get a registration around february this year with the content below? It should have come from Paul Grosso ([email protected]). Harald A ==== registration statement To: [email protected] Cc: mime-sgml IETF working group <[email protected]> Subject: Registration of MIME media type Application/SGML-Open-Catalog MIME media type name: Application MIME subtype name: SGML-Open-Catalog Required parameters: none Optional parameters: charset For use over the Internet, a catalog may use only a single character repertoire. (A character repertoire describes a set of characters, where a character is an atom of information. A character repertoire does not describe any of the common attributes typically associated with a character such as the character's form or coded representation. For example, the letter capital cee is a character, it can take the form C and has the US-ASCII coded representation of 67 decimal.) The mapping from the sequence of octets making up the message body, to the sequence of characters making up the catalog, is indicated by the charset parameter of the Content-Type MIME header line [RFC1521]. The value of the charset parameter must be one that is registered with IANA [RFC1700], or employ an extension-token, such as X-big10. In general, it should be possible to infer the character repertoire and coded character set from the name of the encoding. If no value is supplied, the default shall be US-ASCII. Encoding considerations: Some encodings of coded character sets may require that an additional content-transfer-encoding be applied. Security considerations: This media type contains SGML references to external object, files, and programs. Its use does present security implications due to the access of these entities by SGML systems. However, these security concerns are the same as those for the operation of any SGML system and are addressed in the SGML specifications. Interoperability considerations: The specification for this media type (see "Published specification" below) provides for extensions by allowing for other information, i.e., <keyword, argument+> pairs. The usefulness of such other information will depend on the range of recognition of each such extension. However, the specification indicates that a processor of this media type shall be able to process a catalog even if it does not recognize the meaning of such an extension. Published specification: SGML Open Technical Resolution TR9401:1995, "Entity Management". SGML Open 910 Beaver Grade Road, #3008 Coraopolis, PA 15109 USA <[email protected]> Person and email address to contact for further information: Paul Grosso <[email protected]> ArborText, Inc. 1000 Victors Way Ann Arbor, Michigan 48108 USA Intended usage: LIMITED USE This media type is intended for use with systems that support the SGML Open TR9401:1995 specification. Author/Change controller: Paul Grosso <[email protected]> Additional Information: The SGML Open Catalog specification, TR9401, does not contain any version information. All versions are expected to be backward compatible; amendments to the specification are expected only to recognize certain "extensions" as official parts of the specification.
