## A. Registered Categories

This section contains a number of well known categories and suggestions on how to use them:

- The list of Main Categories consists of those categories that every conforming desktop environment MUST support.

- The list of Additional Categories provides categories that can be used to provide more fine grained information about the application.

- The list of Reserved Categories containes categories that have a desktop-specific meaning.

Note that category names are case-sensitive.

## Main Categories

By including one of the Main Categories in an application's desktop entry file, the application will be ensured that it will show up in a section of the application menu dedicated to this category. If multiple Main Categories are included in a single desktop entry file, the entry may appear more than once in the menu.

Category-based menus based on the Main Categories listed in this specification do not provide a complete ontology for all available applications. Category-based menu implementations SHOULD therefore provide a "catch-all" submenu for applications that cannot be appropriately placed elsewhere.

The table below lists all Main Categories.
