The application/ogg Media Type

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: 

   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.
