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