* SECTION:bookmarkfile
* @title: Bookmark file parser
* @short_description: parses files containing bookmarks
*
* GBookmarkFile lets you parse, edit or create files containing bookmarks
* to URI, along with some meta-data about the resource pointed by the URI
* like its MIME type, the application that is registering the bookmark and
* the icon that should be used to represent the bookmark. The data is stored
* using the
* [Desktop Bookmark Specification](http://www.gnome.org/~ebassi/bookmark-spec).
*
* The syntax of the bookmark files is described in detail inside the
* Desktop Bookmark Specification, here is a quick summary: bookmark
* files use a sub-class of the XML Bookmark Exchange Language
* specification, consisting of valid UTF-8 encoded XML, under the
* <xbel> root element; each bookmark is stored inside a
* <bookmark> element, using its URI: no relative paths can
* be used inside a bookmark file. The bookmark may have a user defined
* title and description, to be used instead of the URI. Under the
* <metadata> element, with its owner attribute set to
* `http://freedesktop.org`, is stored the meta-data about a resource
* pointed by its URI. The meta-data consists of the resource's MIME
* type; the applications that have registered a bookmark; the groups
* to which a bookmark belongs to; a visibility flag, used to set the
* bookmark as "private" to the applications and groups that has it
* registered; the URI and MIME type of an icon, to be used when
* displaying the bookmark inside a GUI.
*
* Here is an example of a bookmark file:
* [bookmarks.xbel](https://git.gnome.org/browse/glib/tree/glib/tests/bookmarks.xbel)
*
* A bookmark file might contain more than one bookmark; each bookmark
* is accessed through its URI.
*
* The important caveat of bookmark files is that when you add a new
* bookmark you must also add the application that is registering it, using
* g_bookmark_file_add_application() or g_bookmark_file_set_app_info().
* If a bookmark has no applications then it won't be dumped when creating
* the on disk representation, using g_bookmark_file_to_data() or
* g_bookmark_file_to_file().
*
* The #GBookmarkFile parser was added in GLib 2.12.
