Policy use cases

[Lily Liu <lily.liu@webmethods.com>]

 

Most of my policy use cases are covered by Dave's taxonomy. However, I just realized there is still an action item open on policies.  So here is the list of messaging use cases that I thought could be addressed by WSN policies:

            Message Subscription

                        Precondition selection

                        Selectors

                        Subscription hints: Dead letter subscription, etc

            Message order

                        Priority based

                        Publisher based

            Message Delivery QoS

                        Durable subscriber

                        Durability in message delivery

                        Shared-state subscribers

Load balance algorithms       

 

Pull notification and queuing are not listed as policy use cases here since I like to have them supported at the same level as the pub/sub pattern. J But they don't need to be included in the core of WS-BaseNotification.
