OGG is a wrapper/container format for Vorbis sound data and various other audiovisual bitstreams developed by the Xiph open source project. Although the initial specification and IANA registration called for the .ogg extension and application/ogg mimetype, whatever content was inside the wrapper, the September 2008 RFC 5334 changed that recommendation and registered audio/ogg and video/ogg mimetypes with corresponding .oga and .ogv extensions for content that is primarily audio or video respectively. The .ogx extension was introduced for use with content that incorporated the OGG Skeleton and for which application/ogg remained appropriate. The .ogg extension was grandfathered to refer to OGG audio with a Vorbis audio encoding. The .spx extension should be used for an OGG audio file with the Speex encoding.
