# Mime Type

A MIME type / (properly) media type / (aka) content type is a standardized two-part identifier for file formats and format contents transmitted on the Internet. 

A media type consists of *top-level type name* and *sub-type name*, possibly ordered into trees, and optional parameters.

### Syntax

`top-level type name / subtype name [ ; parameters ]`

`top-level type name / [ tree. ] subtype name [ +suffix ] [ ; parameters ]`

The top-level type names are:

`application`, `audio`, `example`, `font`, `image`, `message`, `model`, `multipart`, `text`, `video`.

The sub-type name consists of a media type name or other identifying content.
