RE: [soa-rm-ra] Proposed SCA Event Processing Model

How about event interfaces?
There is really very little difference between events and and one way invocations. Also, as Heather mentions WS-eventing is all based on well defined interfaces.

Boris,

With all same respect, anything in the service which communicates with external world other than through official interfaces constitutes degree of coupling.

 In particular, an event in one service may not listen to an event inside another service in other way than though officially defined services event-dedicated interface. 

This is what I mean. Otherwise, we will be unable using the service freely in different service compositions.

With all do respect, event-based does not create additional coupling. Furthermore, considering an industry buzz around events, I think it will be prudent To include events in RA. SCA has done a good job incorporating events, basically through intermediary, thus marrying events and interfaces
