[alf-dev] Why WS-Notification Rejected

["Robert Brady" <rbrady@xxxxxxxxx>]

Is my understanding that WS-Notification was rejected for the following disadvantages correct?

 

WS-Notification vs. Ordinary WS

=========================

 

 

Advantages of WS-N

 

* Standardized pub/subscribe/notify pattern

* Centralized configuration of ALF via tool subscription

* An implementation exists in Java already (Apache Pubscribe)

 

 

Disadvantages of WS-N

 

* Heavyweight, Onerous implementation: Each tool needs to run a WS

implementing WS-N and its dependencies (e.g., a subscription is a stateful

resource modeled as a WS-Resource, utilizing WS-ResourceLifetime operations).

 

* Functionality required that's not used: Alf would be the only tool subscriber, so

the WS-Topics spec of WS-N not needed.

 

Thanks
