The first module produces output (data), so

module (action) ->data (eg. raster map) -> module (action)

It should add connection between items (line with arrow). At the
beginning the modeler has not been design to define relations
manually, they should be updated based on action parameters you enter.
Speaking about manual definition of relation you can expect some bugs,
please report them on trac (with reproducible examples).
