According to xdg: "This section contains a number of well known categories and suggestions on how to use them. The list of Main Categories consist of those categories that every conforming desktop environment MUST support. By including one of these 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." [1]
