If it were needed to be called on each file while loading a directory 
(which would only be for limited things like the mime type) then we 
could also have an API to return a specific metadata for each file in a 
directory in one shot.

EG

GetMimeTypesForFilesInFolder
   input DBUS_TYPE_STRING s (the folder uri)
   output DBUS_TYPE_DICT  a{ss} (the metadata as filename, mimetype)

Most of the other metadata would be retrieved on demand by users 
requesting to see additional metadata for a file so the previous API 
should suffice for that.
