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