+Status of this Memo
+
+   This document specifies an Internet standards track protocol for the
+   Internet community, and requests discussion and suggestions for

+   Official Protocol Standards" (STD 1) for the standardization state
+   and status of this protocol.  Distribution of this memo is unlimited.

+Abstract
+
+   The Ogg Bitstream Format aims at becoming a general, freely-available
+   standard for transporting multimedia content across computing
+   platforms and networks.  The intention of this document is to define
+   the MIME media type application/ogg to refer to this kind of content
+   when transported across the Internet.  It is the intention of the Ogg
+   Bitstream Format developers that it be usable without intellectual
+   property concerns.
+
+Conventions used in this Document
+
+   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
+   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
+   document are to be interpreted as described in RFC 2119 [2].
+
+1. The Ogg Bitstream Format
+
+   The Ogg Bitstream format has been developed as a part of a larger
+   project aimed at creating a set of components for the coding and
+   decoding of multimedia content (codecs) which are to be freely
+   available and freely re-implementable both in software and in
+   hardware for the computing community at large, including the Internet
+   community.
+
+   Raw packets from these codecs may be used directly by transport
+   mechanisms that provide their own framing and packet-separation
+   mechanisms (such as UDP datagrams).

+
+RFC 3534             The application/ogg Media Type             May 2003
+
+
+   One such framing and content-separation mechanism is the real-time
+   transport protocol (RTP).  RTP allows the streaming of synchronous
+   lossy data for broadcasting and similar purposes.  If this function
+   is desired then a separate RTP wrapping mechanism should be used.  A
+   wrapping mechanism is currently under development.
+
+   For stream based storage (such as files) and transport (such as TCP
+   streams or pipes), Ogg codecs use the Ogg Bitstream Format to provide
+   framing/sync, sync recapture after error, landmarks during seeking,
+   and enough information to properly separate data back into packets at
+   the original packet boundaries without relying on decoding to find
+   packet boundaries.  The application/ogg MIME type refers to this kind
+   of bitstreams, when no further knowledge of the bitstream content
+   exists.
+
+   The bitstream format in itself is documented in [1].
+
+2. Registration Information
+
+   To: ietf-types@iana.org
+
+   Subject: Registration of MIME media type application/ogg
+
+   MIME media type name: application
+
+   MIME subtype name: ogg
+
+   Required parameters: none
+
+   Optional parameters: none
+
+   Encoding Considerations:
+
+   The Ogg bitstream format is binary data, and must be encoded for
+   non-binary transport; the Base64 encoding is suitable for Email.
+   Binary encoding could also be used.
+
+   Security Considerations:
+
+   As the Ogg bitstream file is a container format and only a carrier of
+   content (such as Vorbis audio) with a very rigid definition (see
+   [1]), this format in itself is not more vulnerable than any other
+   content framing mechanism.  The main security consideration for the
+   receiving application is to ensure that manipulated packages can not
+   cause buffer overflows and the like.  It is possible to encapsulate
+   even executable content in the bitstream, so for such uses additional
+   security considerations must be taken.

+
+RFC 3534             The application/ogg Media Type             May 2003
+
+
+   Ogg bitstream files are not signed or encrypted using any applicable
+   encryption schemes.  External security mechanisms must be added if
+   content confidentiality and authenticity is to be achieved.
+
+   Interoperability considerations:
+
+   The Ogg bitstream format has proved to be widely implementable across
+   different computing platforms.  A broadly portable reference
+   implementation is available under a BSD license.
+
+   The Ogg bitstream format is not patented and can be implemented by
+   third parties without patent considerations.
+
+   Published specification:
+
+   See [1].
+
+   Applications which use this media type:
+
+   Any application that implements the specification will be able to
+   encode or decode Ogg bitstream files.  Specifically, the format is
+   supposed to be used by subcodecs that implement, for example, Vorbis
+   audio.
+
+   Additional information:
+
+   Magic number(s):
+
+   In Ogg bitstream files, the first four bytes are 0x4f 0x67 0x67 0x53
+   corresponding to the string "OggS".
+
+   File extension: .ogg
+
+   Macintosh File Type Code(s): OggS
+
+   Object Identifier(s) or OID(s): none

+
+   Questions about this proposal should be directed to Linus Walleij
+   <triad@df.lth.se>.  Technical questions about the Ogg bitstream
+   standard may be asked on the mailing lists for the developer
+   community.  <http://www.xiph.org/archives/>

+   Intended usage: COMMON
