List of common media types

List of common media types

IANA manages a registry of media types and character encodings. The organization makes a list available to the public through the Web. Some of the more notable media types used on the Web are listed below:

Type application

For Multipurpose files.

• application/atom+xml: Atom feeds
• application/ecmascript: ECMAScript/JavaScript; Defined in RFC 4329 (equivalent to application/javascript but with stricter processing rules)
• application/EDI-X12: EDI X12 data; Defined in RFC 1767
• application/EDIFACT: EDI EDIFACT data; Defined in RFC 1767
• application/json: JavaScript Object Notation JSON; Defined in RFC 4627
• application/javascript: ECMAScript/JavaScript; Defined in RFC 4329 (equivalent to application/ecmascript but with looser processing rules) It is not accepted in IE 8 or earlier – text/javascript is accepted but it is defined as obsolete in RFC 4329. The “type” attribute of the <script> tag in HTML5 is optional and in practice omitting the media type of JavaScript programs is the most interoperable solution since all browsers have always assumed the correct default even before HTML5.
• application/octet-stream: Arbitrary binary data.^[4] Generally speaking this type identifies files that are not associated with a specific application. Contrary to past assumptions by software packages such as Apache this is not a type that should be applied to unknown files. In such a case, a server or application should not indicate a content type, as it may be incorrect, but rather, should omit the type in order to allow the recipient to guess the type.^[5]
