MIME Applications Associations

This specification allows users, system administrators, application vendors, and distributions, to control which application should open a file by default, and which applications should be shown as supporting a given MIME type (possibly overriding what the .desktop file for the application lists).


Discussion of this specification should occur on xdg.


This specification is hosted in git, see mime-apps-spec.
