What is MIME type "application/itn"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

application/itn is a MIME type used for storing travel itinerary data. It tells software that the file holds structured details about travel plans.

Files of this type usually store the schedule of trips, including dates, times, stops, and booking information. They are read and written by dedicated travel planning applications. These files use a specific format so that related programs can exchange and display travel data accurately.

Main use case: Organizing and sharing detailed travel itineraries.
Other key uses: Managing business trip schedules and leisure travel plans.
Functionality: It enables structured data exchange between travel management systems.

The file often appears with the extension ITN. You can check more details about this file type through external resources such as the IANA Media Types page.

FAQ

What is a MIME type?

A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.

MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.

MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.

How do I find the MIME type for a file?

You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.

Why are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
