Correction: the top option is specified as "-t top", not "top".
The command line is
ke [-q] [-m] [script.mkr] [-t top]
where
-q is quiet mode with minimal output
-m is no-menu mode
script.mkr is your MKR language input
top is name of universal concept (defaults to "existent")
Thus for OWL you can use
ke -t Thing
and for RDF you can use
ke -t Resource
