And this is what the application/ogg MIME descriptor is supposed to look like. Same request for comments here... Linus Walleij --------- MIME media type name: application MIME subtype name: ogg Required parameters: none Optional parameters: none Encoding Considerations: The OggSQUISH data 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 OggSQUISH file is a container format and only a carrier of content (such as Vorbis audio) with a very rigid definition (see [OGG]), 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. OggSQUISH 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 OggSQUISH format has proved to be widely implementable across different computing platforms. An example implementation exists that has been compiled on numerous platforms. The QggSQUISH format is not patented and can be implemented by third parties without patent considerations. Published specification: See [OGG]. Applications which use this media type: Any application that implements the specification will be able to encode or decode OggSQUISH files. Specifically, the format is supposed to be used by subcodecs that implement for example Vorbis audio. Additional information: Magic number(s): In OggSQUISH files, the first four bytes are 0x4f 0x67 0x67 0x53 corresponding to the string "OggS". File extension: .ogg Macintosh File Type Code(s): none Object Identifier(s) or OID(s): none Person & email address to contact for further information: Questions about this proposal should be directed to Linus Walleij <triad@df.lth.se>. Technical questions about the OggSQUISH standard may be asked on the mailing lists for the developer community. <http://www.xiph.org/archives/> Intended usage: COMMON Author/Change controller: This document was written by Linus Walleij <triad@df.lth.se>, changes of this document will be handled by him or a representative of the Xiphophorus company or the associated development communities. The OggSQUISH format is controlled by the Xiphophorus company and the respective development communities.
