[rules-users] Question on modeling facts

I am trying to write rules to distill down a minimal train schedule from a set of overlapping train schedules. A train schedule contains a train identifier, a schedule that it runs on, and a set of train stops. A rule that I would like to write is to combine one or more train schedules if more than one train runs on the same day (ie has the same schedule) and stops at the same stops. This ignores the train identifier and will discard all other train schedules that have a different train identifier but have the same schedule and stops. I am wondering how to model the equality test for the same set of stops. Can I have my Train fact contain a collection of stops and then compare the collections for equality? Will this be efficient? Is there a better way to model this? Any and all help will be greatly appreciated. Brett -- View this message in context: http://drools.46999.n3.nabble.com/Question-on-modeling-facts-tp2895595p28...
