I am  working on a pattern language in perl that will generate all the
needed GNUE stuff :

the input is like the list in the last mail,
here i create an event type out of the log pattern, with the parameters
of the event to track. Each log_pattern represents an important logged
business event that tracks who used it and where. the process function
returns a list of costs and revenues out of the transaction.

sub log_pattern # an action that is tracked by who did it and when
{
    my $action = shift;
    AddClass($repository,$action . "Event");                          
# the class called ids

    AddField($repository,'BusinessEntity',$action,
             BaseType($repository,'Event'));            # the id of a field
    DefineEvent($repository,'On' . $action ,
                {
                    Parameters => {
                        # Name         Type
                        "UsedBy"    => TypeRef($repository,"CustomerAgent"),
                        "AtTime"    => BaseType($repository,"timestamp"),
                        "Duration"    => BaseType($repository,"timerange"),
                        "AtLocation"  => TypeRef($repository,"LocationRef"),
                    },
                    Result => {
                        "Costs"        => TypeRef($repository,"Transactions"),
                        "Revenue"       => TypeRef($repository,"Transactions"),
                    }
                }
                );
}
