- GConf configuration source
A storage location in the GConf repository. For example, xml:readonly:/etc/gconf/gconf.xml.defaults.

- GConf path file
A file that lists the GConf configuration sources, and the order in which to search the sources.
- GConf schema
A collective term for a schema key and a schema object.
- GConf schema definition file

- GConf schema key
A key that stores a schema object for a preference key. For example, /schemas/desktop/gnome/interface/font_name is a schema key for the /desktop/gnome/interface/font_name preference key.
- GConf schema object

MIME source XML files are located in the $XDG_DATA_DIRS:$XDG_DATA_HOME/mime/packages directory.
- MIME type
