<p>Thanks to TIBCO’s Scott Vorthmann for updating me on the <a title="PDF - SCA document" href="http://www.osoa.org/download/attachments/35/SCA_Assembly_Extensions_for_Event_Processing_and_PubSub_V1_0.pdf?version=1" target="_blank">SCA-Assembly-Extensions-for-Event-Processing-and-Pub/Sub draft</a>, which <a title="InfoQ on SCA for EP and PubSub" href="http://www.infoq.com/news/2009/05/SCAevents" target="_blank">was reported on InfoQ</a> a few months ago. This seems to be mostly an Oracle + IBM effort, and seemingly is occuring outside of <a title="OASIS home page" href="http://www.oasis-open.org/home/index.php" target="_blank">OASIS</a>, which seems strange if it is true.</p> <ul> <li>There is some <a title="org.oasis-open.lists.soa-rm-ra email exchange on WS-* and SCA-EP-PubSub" href="http://markmail.org/message/7mtgrcxyaysnzqd3#query:SCA%20Event%20Processing+page:1+mid:ib635qmcnnlydgnb+state:results" target="_blank">interesting commentary</a> on its relevence versus the WS-Eventing / -Notification efforts. Possibly all these are together in the same logjam. Some of the associated comments seem to make the case that there is a difference between message processing and event processing - even if most CEP tools utilise messaging systems as transports for events, the appearance of a message *is* an event, etc….</li> <li>This <a title="Wikipedia reference" href="http://en.wikipedia.org/wiki/Service_component_architecture" target="_blank">SCA</a> effort seems to have similarities with the <a title="OMG EMP wiki" href="http://www.omgwiki.org/soaeda/doku.php" target="_blank">OMG Event Metamodel and Profile</a> initiative - indeed “SCA-AE4EP&PS” would likely be an input to EMP (if either take off).</li> <li>Work seems to be progressing on an initial implementation anyway as a part of the <a title="Apache Tuscany SCA home" href="http://cwiki.apache.org/confluence/display/TUSCANY/Home" target="_blank">Apache Tuscany</a> project - they have a page <a title="Apache Tuscany SCA on Java Event Processing" href="http://cwiki.apache.org/confluence/display/TUSCANY/SCA+Java+Event+Processing" target="_blank">on event processing</a> too - but one gets the impression the differences between services, components, and event processing components might be a problem here.</li> </ul> <a href="http://www.addtoany.com/share_save?&linkurl=http%3A%2F%2Ftibcoblogs.com%2Fcep%2F2009%2F08%2F10%2Fsca-for-event-processing-and-pubsub%2F&linkname=SCA%20for%20Event%20Processing%20and%20PubSub%26%238230%3B"><img src="http://tibcoblogs.com/cep/wp-content/plugins/add-to-any/share_save_120_16.png" width="120" height="16" alt="Share/Save/Bookmark" /></a> <p>Related posts:<ol><li><a href="http://tibcoblogs.com/cep/2009/06/24/project-managing-an-event-processing-application/" rel="bookmark" title="Permanent Link: Project Managing an Event Processing Application">Project Managing an Event Processing Application</a></li><li><a href="http://tibcoblogs.com/cep/2008/12/09/omg-bpmn2-conversations-vs-event-terminology/" rel="bookmark" title="Permanent Link: OMG BPMN2 Conversations vs Event terminology">OMG BPMN2 Conversations vs Event terminology</a></li><li><a href="http://tibcoblogs.com/cep/2009/04/20/extreme-event-processing-5k-eps/" rel="bookmark" title="Permanent Link: eXtreme Event Processing: 5K EPS…">eXtreme Event Processing: 5K EPS…</a></li></ol></p><img src="http://feeds.feedburner.com/~r/ComplexEventProcessing/~4/D3cVg6e8BkA" height="1" width="1" />
