[Issue 80] - Eventing Extensions

[Jeff Mischkinsky <jeff.mischkinsky@oracle.com>]

hi,
Relative to http://www.osoa.org/jira/browse/ASSEMBLY-80 (Create an  
Event Processing Model for SCA), I'd like to give everyone a heads up  
that an proposal for extending Assembly for Eventing as been published:
   (from http://www.osoa.org/display/Main/2009/04/30/SCA+Assembly+Extensions+for+Event+Processing+and+Pub+Sub+V1.00+Published)

"The OSOA Collaboration has published the V1.00 version of the SCA  
Assembly Extensions for Event Processing and Pub/Sub specification.

This document describes the Event Processing and Pub/Sub Extensions  
for the SCA Assembly Model, which deals with

   1. Event Processing, which is computing that performs operations on  
events, including creating, reading, transforming and deleting events  
or event objects/representations. Event Processing components interact  
by creating event messages which are then distributed to other Event  
Processing components.  An Event Processing component can, in  
addition, interact with other SCA components using SCA's regular  
service invocation mechanisms.
   2. Publication and Subscription (often shortened to Pub/Sub), which  
is a particular style of organizing the components which produce and  
consume events in which the producing components are decoupled from  
the consuming components. Components that are interested in consuming  
events specify their interest through a subscription rather than an  
interface. The same event may be received by multiple subscribers.

The document starts with a description of the Event Processing and Pub/ 
Sub extensions and then goes on to show the changes to the relevant  
parts of the SCA Assembly specification that are required by these  
extensions. This document is based on the OSOA SCA Assembly  
Specification V1.00."


cheers,
  jeff
