There are two classes of type: discrete and multipart.ĭiscrete types are types which represent a single file or medium, such as a single text or music file, or a single video.Ī multipart type represents a document that's comprised of multiple component parts, each of which may have its own individual MIME type or, a multipart type may encapsulate multiple files being sent together in one transaction.įor example, multipart MIME types are used when attaching multiple files to an email. The parameter values can be case-sensitive. MIME types are case-insensitive but are traditionally written in lowercase. To specify a UTF-8 text file, the MIME type text/plain charset=UTF-8 is used. If no charset is specified, the default is ASCII ( US-ASCII) unless overridden by the user agent's settings. A MIME type always has both a type and a subtype, never just one or the other.Īn optional parameter can be added to provide additional details: type/subtype parameter=valueįor example, for any MIME type whose main type is text, you can add the optional charset parameter to specify the character set used for the ics) files.Įach type has its own set of possible subtypes. The subtype identifies the exact kind of data of the specified type the MIME type represents.įor example, for the MIME type text, the subtype might be plain (plain text), html ( HTML source code), or calendar (for iCalendar/. The type represents the general category into which the data type falls, such as video or text. Permissions-Policy: xr-spatial-tracking ExperimentalĪ MIME type most commonly consists of just two parts: a type and a subtype, separated by a slash ( /) - with no whitespace between: type/subtype.

The optional strict argument has the same meaning as with the guesstype() function. Permissions-Policy: picture-in-picture Experimental The extensions are not guaranteed to have been associated with any particular data stream, but would be mapped to the MIME type type by guesstype().
