Subject: Re: [sca-assembly] TIBCO eventing proposal
Thanks for sending this out. Even though pictures/examples are missing, I *think* I get the general idea. Few questions/comments about the details (not the overall design) that immediately came to mind: 1) Section 3.1 Exposing a Service as a Consumer says "The name of such an operation is understood to define an event type ..." Can you elaborate on why the operation name has to define the event type? Perhaps I misunderstood what the doc says, but from an event processing perspective, I don't think you want to restrict which events are delivered to a method based on its method name. For example, an onMessage(...) method may (and typically does) processes any event that is delivered. The name onMessage has no relevance wrt which event types it wants to consume. 2) Section 3.2 Exposing a Reference as a Producer does not say anything about the cardinality of the reference. I assume it is 0..n. 3) WRT the minimum-novelty goal, I should point out that the W3C WSRA WG that is standardizing WS-Eventing and friends has found the need to separate the event type description from WSDL. See http://www.w3.org/2002/ws/ra/edcopies/wseventing.html#Advertising There is also a plan (not sure if it is approved by the WG yet) for refactoring the event description part in a separate spec in the WG. Trying to fit/overlay event description into the WSDL portType/method model does have its problems. 4) In Section 7 Domain Channels, is your objection to the syntax or to the fact that a pub/subcriber deep down in a nested composite is "connected" to a domain-level channel, i.e. visibility issue? 5) WRT channelBinding.sca, is that really necessary given that binding.sca is magic anyway? Wouldn't binding.sca fit the bill? Thanks! -Anish -- On 11/25/2009 5:13 PM, Scott Vorthmann wrote: > Here is our proposal, in not a great deal of detail.
