Hi, the USEFOR WG is about to finish <http://tools.ietf.org/html/draft-ietf-usefor-usepro> Section 4 of this draft -12 contains four MIME types: message/news (OBSOLETE) application/news-transmission (update) application/news-groupinfo (new) application/news-checkgroups (new) See the registration templates below, Frank --- MIME type name: message MIME subtype name: news Required parameters: none Optional parameters: charset, compare message/rfc822 Encoding considerations: compare message/rfc822 (RFC 2046) Security considerations: OBSOLETE, use message/rfc822. Interoperability considerations: Rarely used; and therefore often handled as application/octet-stream. Disposition should by default be inline. Published specification: [SON-OF-1036], RFCXXXX Applications that use this media type: Some old mail and news user agents. Intended usage: OBSOLETE Author: Henry Spencer Change controller: IETF --- MIME type name: application MIME subtype name: news-transmission Required parameters: none Optional parameters: One and only one of "usage=moderate", "usage=inject", or "usage=relay". Encoding considerations: A transfer-encoding different from that of the article transmitted MAY be supplied to ensure correct transmission over some 7bit transport medium. Security considerations: A news article may be a control message, which if processed could have effects on the recipient host's system beyond just storage of the article. Published specification: RFCXXXX Body part: A complete proto-article ready for injection into Netnews or an article being relayed to another agent. Applications that use this media type: Injecting agents, Netnews moderators. Intended usage: COMMON Change controller: IETF --- MIME type name: application MIME subtype name: news-groupinfo Required parameters: none Optional parameters: charset, which MUST be a charset registered for use with MIME text types and has the same syntax as the parameter defined for text/plain [RFC2046]. Specifies the charset of the body part. If not given, the charset defaults to US-ASCII [ASCII]. Encoding considerations: 7bit or 8bit MUST be used to maintain compatibility. Security considerations: None. Interoperability considerations: Disposition should by default be inline. Applications that use this media type: Control message issuers, relaying agents, serving agents. Published specification: RFCXXXX Intended usage: COMMON Change controller: IETF --- MIME type name: application MIME subtype name: news-checkgroups Required parameters: none Optional parameters: charset, which MUST be a charset registered for use with MIME text types and has the same syntax as the parameter defined for text/plain [RFC2046]. Specifies the charset of the body part. If not given, the charset defaults to US-ASCII [ASCII]. Encoding considerations: 7bit or 8bit MUST be used to maintain compatibility. Security considerations: This media type provides only a means for conveying a list of newsgroups and does not provide any information indicating whether the sender is authorized to state which newsgroups should exist within a hierarchy. Such authorization must be accomplished by other means. Interoperability considerations: Disposition should by default be inline. Applications that use this media type: Control message issuers, relaying agents, serving agents. Published specification: RFCXXXX Intended usage: COMMON Change controller: IETF ---
