[rules-users] Using GUVNOR for FUSION RULES

Hi all, i am novice on GUVNOR, but i would like to define my fusion rules by graphical tool. An example of my rules is: rule "radiation-event" salience 10 no-loop when $obs : RadiationObservation( $obsLocation : location, value > 10 ) over window:length(1) from entry-point lowLevelSensorStream not RadiationEvent( this meets[ 25s ] $obs, location geoIsWithinDistance[ 5m ] $obsLocation ) then insert(new RadiationEvent( $obs, "Radiation over 10", Event.THREAT_HIGH, $obsLocation, $obs.getSensor() )); end rule "radiation-update" salience 5 no-loop when $obs : RadiationObservation( $obsLocation : location, value > 10 ) over window:length(1) from entry-point lowLevelSensorStream $event : RadiationEvent( this meets[ 25s ] $obs, location geoIsWithinDistance[ 5m ] $obsLocation ) then Event e = Event.clone($event); e.addObservation($obs); insert( e ); retract($event); retract($obs); end Is it possibile to define rules such the above using GUVNOR? Are there some documentation or tutorial? Thanks a lot in advance, Matteo Cusmai.
