Correct? No, it is a 1 to 1 relationship between the encoding and the quality rank. That means there are no equal encodings with different qualities. I just wanted to model the trivial relationship "encoding A is better than encoding B". I'm not sure if that's really a good solution...

There should be more than one device encodings possible. But the rule then behaves like this: "Find the best/highest encoding for every seperate device-encoding asserted". And this is always this single device-encoding, because there is no comparison with several encodingQualityOrders. I guess that is the case here, correct me if i'm wrong... Thank you for your answers. I just noticed the other solutions from Johannes Echterhoff and Jasen Morris, which look like solving the problem. But not as short as I thought it could be ;-) Regards Sven > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Behalf Of [EMAIL PROTECTED] > Sent: Tuesday, August 24, 2004 11:36 AM > To: [EMAIL PROTECTED] > Subject: JESS: Defining an order > > > Hello, > > i'm new to jess.
