A new Request for Comments is now available in the online RFC libraries. Note: This is a PostScript RFC, a secondary version is available in ASCII. The secondary ASCII version may lack figures and the information encoded in typographic variation (italics, boldface, etc.). Since this information often provides essential context, the ASCII version is at best incomplete and at worst misleading. Anyone expecting to understand this document is strongly encouraged to obtain the PostScript version. RFC 1341: Title: MIME (Multipurpose Internet Mail Extensions): Mechanisms for Specifying and Describing the Format of Internet Message Bodies Author: N. Borenstein & N. Freed Mailbox: nsb@bellcore.com, ned@innosoft.com PS-Pages: 69 ASCII-Pages: 80 PS-Characters: 347,082 ASCII-Characters: 211,117 Updates/Obsoletes: none RFC 822 defines a message representation protocol which specifies considerable detail about message headers, but which leaves the message content, or message body, as flat ASCII text. This document redefines the format of message bodies to allow multi-part textual and non-textual message bodies to be represented and exchanged without loss of information. This is based on earlier work documented in RFC 934 and RFC 1049, but extends and revises that work. Because RFC 822 said so little about message bodies, this document is largely orthogonal to (rather than a revision of) RFC 822. In particular, this document is designed to provide facilities to include multiple objects in a single message, to represent body text in character sets other than US-ASCII, to represent formatted multi-font text messages, to represent non-textual material such as images and audio fragments, and generally to facilitate later extensions defining new types of Internet mail for use by cooperating mail agents. This document does NOT extend Internet mail header fields to permit anything other than US-ASCII text data. It is recognized that such extensions are necessary, and they are the subject of a companion document (RFC 1342). This document is the product of the Internet Message Extensions Working Group of the IETF. This is now a Proposed Standard Protocol. This RFC specifies an IAB standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "IAB Official Protocol Standards" for the standardization state and status of this protocol. Distribution of this memo is unlimited. This announcement is sent to the IETF list and the RFC-DIST list. Requests to be added to or deleted from the IETF distribution list should be sent to IETF-REQUEST@NRI.RESTON.VA.US. Requests to be added to or deleted from the RFC-DIST distribution list should be sent to RFC-REQUEST@NIC.DDN.MIL. RFCs can be obtained via FTP from FTP.NISC.SRI.COM, NIS.NSF.NET, NISC.JVNC.NET, VENERA.ISI.EDU, WUARCHIVE.WUSTL.EDU, SRC.DOC.IC.AC.UK, FTP.CONCERT.NET, or NIC.DDN.MIL. Details on obtaining RFCs via FTP or EMAIL may be obtained by sending an EMAIL message to "rfc-info@ISI.EDU" with the message body "help: ways_to_get_rfcs".
