OETF #19: Multipurpose Media Type Identifier (MMTI)

Recommended Posts

(leave a comment if you want to register an MMTI type)

Multipurpose Media Type Identifier, Version 1.0

Purpose

The MMTI provides a way to identify data types without an extension, and to differentiate files with the same extension. One can only make so many recognisable extensions with 4 latin characters. Some data is not to be used as a file, but still needs a way to be identified.

Format

An MMTI string takes the format of category/type. For example, a Lua script would be application/lua. A CPIO archive would be archive/cpio, etc. MMTI strings should only use US-ASCII characters.

Unregistered MMTI strings

MMTI strings that aren't registered should prefix the type with x-, such as application/x-zoryapkg.

Categories

As of Version 1.0, the following categories are available for use.

  • application - Any type of format which is to be executed
  • archive - Any type of format which is used to archive other files
  • media - Any type of format which contains video or audio
  • model - Any type of format which contains data used to construct a 3D model
  • text - Any type of format which is used to transmit textual data
  • message - Any type of format which is used to transmit data over a network
  • other - Any type of format which is not covered in the other categories

Registed MMTI types.

Would be cool if text/lua-table was added, it's what is outputted by OpenOS's serialization library, MineOS filesystem's writeTable/readTable, Fuchas's liblon, etc.

This is mostly used for configuration files and thus its extension varies, sometimes .cfg sometimes .dat sometimes something else. Only Fuchas uses .lon for all serialized lua table.

Oh and also please register text/ohml, extension is .ohml and it's described here
