A Media Type is a description of a file format plus a description of the interactions a client can make when viewing the file. Media Types are referenced using their identifier. In online documentation the term Media Type is often used to mean either the Media Type description or the Media Type identifier.
A simple example of a media type is the GIF format, identified using image/gif. It has no interactions (it doesn't link to anything) and has a specification that tells clients how they should display it.
Media Types are specified in rfc2046.
Media Type identifiers are constructed using a tree part, a subtype and optionally a suffix. A full example is: application/vnd.delftsolutions.contact_us.v1+json. Here the tree is application, the subtype is vnd.delftsolutions.contact_us.v1 and the suffix is json.
The available tree parts are limited to:
- application (everything not covered under the other categories)
- audio (rendered as audio)
- font (can be used to render text)
- example (for use in documentation)
- image (rendered as a static image)
- text (for human consumption as text)
- video (contains video)
Commonly used suffixes are:
If you create your own media type identifiers you usually want to put them in the application tree and use a vnd.<companyname> prefix on the subtype.
