Use the gnomevfs module (in gnome-python, probably). It's not that well
documented; you probably want gnomevfs.get_mime_type().

Use gnomevfs.mime_get_default_application(). For example:
import gnomevfs, gobject
def open_uri(uri):
mime = gnomevfs.get_mime_type (uri)
scheme = gnomevfs.get_uri_scheme (uri)
# http://bugzilla.gnome.org/show_bug.cgi?id=411560
id, name, command, multi, paths_for_local, schemes, term =
gnomevfs.mime_get_default_application (mime)
if scheme == 'file' and paths_for_local:
return gobject.spawn_async ([command,
gnomevfs.get_local_path_from_uri (uri)], flags=gobject.SPAWN_SEARCH_PATH)
elif scheme == 'file' or scheme in schemes:
return gobject.spawn_async ([command, uri],
flags=gobject.SPAWN_SEARCH_PATH)
else:
for id, name, command, multi, paths_for_local, schemes, term in
gnomevfs.mime_get_short_list_applications (mime) +
gnomevfs.mime_get_all_applications (mime):
if scheme in schemes:
return gobject.spawn_async ([command, uri],
flags=gobject.SPAWN_SEARCH_PATH)
return False
open_uri ("file:///path/to/file")

Use gtk.Clipboard.set_with_data with
targets=gtk.target_list_add_uri_targets(); see gtk.SelectionData.
