Media types can optionally define companion data, known as parameters. All media types should be registered using the IANA registration procedures. For the efficiency and flexibility of the media type registration process, different structures of sub-type names can be registered in registration “trees” that are distinguished by the use of faceted names, e. Currently the following trees are created: standard, vendor, personal or vanity, unregistered “x. Vendor tree is used for media types associated with publicly available products. The terms “vendor” and “producer” are considered equivalent in the context.
Industry consortia as well as non-commercial entities can register media types in the vendor tree. A registration in the vendor tree may be created by anyone who needs to interchange files associated with some software product or set of products. However, the registration belongs to the vendor or organization producing the software that employs the type being registered, and that vendor or organization can at any time elect to assert ownership of a registration done by a third party. Personal or Vanity tree includes media types created experimentally or as part of products that are not distributed commercially. Types in this tree cannot be registered.
Media types with names beginning with “x-” are no longer considered to be members of this tree since January 2013. All media types should be registered using the simplified IANA registration procedures for vendor and personal trees or using the standards procedure for standards tree. If this is not possible, the media type can, after an approval by both the media types reviewer and the IESG, be registered in the proper tree with its unfaceted name. Suffix is an augmentation to the media type definition to additionally specify the underlying structure of that media type. MIME-aware applications such as mail clients and web browsers render files of different MIME-types. It is supported by most Unix systems. The first part is called the content-type, and the second part is called the view-command.
