This section summarizes hundreds of MIME types in 10 tables. Each table lists the MIME media types within a particular primary type (image, text, etc.).

The information is gathered from many sources, including the IANA media type registry, the Apache mime.types file, and assorted Internet web pages. We spent several days refining the data, plugging holes, and including descriptive summaries from cross-references to make the data more useful.

This may well be the most detailed tabular listing of MIME types ever compiled. We hope you find it handy!

D.4.1 application/*

Table D-3 describes many of the application-specific MIME media types.

D.4.7 multipart/*

Multipart MIME types are composite objects that contain other objects. The subtype describes the implementation of the multipart packaging and how to process the components. Multipart media types are summarized in Table D-9.

Table D-9. "Multipart" MIME types

MIME type Description Extension Contact and reference
multipart/alternative The content consists of a list of alternative representations, each with its own Content-Type. The client can select the best supported component.   RFC 1341
multipart/appledouble Apple Macintosh files contain "resource forks" and other desktop data that describes the actual file contents. This multipart content sends the Apple metadata in one part and the actual content in another part.   http://www.isi.edu/in-notes/iana/assignments/media-types/multipart/appledouble
multipart/byteranges When an HTTP message includes the content of multiple ranges, these are transmitted in a "multipart/byteranges" object. This media type includes two or more parts, separated by MIME boundaries, each with its own Content-Type and Content-Range fields.   RFC 2068
multipart/digest Contains a collection of individual email messages, in an easy-to-read form.   RFC 1341
multipart/encrypted Uses two parts to support cryptographically encrypted content. The first part contains the control information necessary to decrypt the data in the second body part and is labeled according to the value of the protocol parameter. The second part contains the encrypted data in type application/octet-stream.   RFC 1847
multipart/form-data Used to bundle up a set of values as the result of a user filling out a form.   RFC 2388
multipart/header-set Separates user data from arbitrary descriptive metadata.   http://www.isi.edu/in-notes/iana/assignments/media-types/multipart/header-set
multipart/mixed A collection of objects.   RFC 1341
multipart/parallel Syntactically identical to multipart/mixed, but all of the parts are intended to be presented simultaneously, on systems capable of doing so.   RFC 1341
multipart/related Intended for compound objects consisting of several interrelated body parts. The relationships between the body parts distinguish them from other object types. These relationships often are represented by links internal to the object's components that reference the other components.   RFC 2387
multipart/report Defines a general container type for electronic mail reports of any kind.   RFC 1892
multipart/signed Uses two parts to support cryptographically signed content. The first part is the content, including its MIME headers. The second part contains the information necessary to verify the digital signature.   RFC 1847
multipart/voice-message Provides a mechanism for packaging a voice message into one container that is tagged as VPIM v2-compliant.   RFCs 2421 and 2423

D.4.8 text/*
