The role of agents in Business Process Management (BPM) has surely been discussed before, but I have not yet seen a concise account on the core concepts...
Hi there fellow CEP'ers and ECA'ers, After being badgered by Mark Palmer, in the nicest possible way, I finally managed to join up. FYI I have been involved in...
Has anyone in the group looked at WS-Notification and how this might relate to CEP based systems? My thoughts are that ECA's really took off when MOM did and...
Hi Steve, Welcome! Please refresh my mind on the relationship between WS-Notification and ECA rules - are they the same? Also a couple of questions about...
WS-Notification deals with publish/subscribe connections among Web Services. I am trying now to sort out among the IBM people that are active in these standard...

Has the statute of limitations on replies passed? I enjoy deconstructing terms. To pick on two points: 1) The events of interest are often/usually/always...
... No official policy exists in this group :-) ... But the inbound raw streaming data "already exists" - so you are "processing" stuff that "already exists,"...
Seth, no Statute of limitations here! There's a lot of confusion about event streams. Here are two points of confusion: 1. an event processing tool usually...

Julian, sorry to be so long getting back to you -- been travelling. Absolutely what you say is true. The key is simply capturing relational information about...
Hi David, Any thoughts on using an XML database powered by XQuery? It can easily aggregate any kind of content and also federate any database. Do advise... ...
Just to clarify, the characterization David has made of ESP systems might hold for some academic work in stream processing, but it's not true for some...
Ash - XML databases, as well as other forms of DBMS access, must be combined in-line with event stream processing. XML as a DDL/DML, per se, don't change the...
I wanted to re-visit, very briefly, the discussion of ESP and CEP and offer a refinement of these terms. I am searching for a way to reconcile this because...
Hi Ash, as implementations of CEP take off I would expect most of them to use XML representations of events. I am not familiar with XQUERY, sorry to say. But,...
Hi David, Glad to hear from you. I agree that XML will be the de-facto technology in most of the CEP implementations in time. In brief, XQuery is the query...
Mark, good to hear from you! We have an interesting discussion here -- one that I hoped to engender a while ago. We do need standards and checklists for event...
Hi David, Good point regarding the WHAT and HOW... I believe that CEP lends itself well to the heirarchical and flexible nature of XML. XQuery can be used with...
Mark, At first glance: Useful! Thanks for putting the pages together. But your diagram makes ESP look like little more than filtering. ESP creates Derived...
Some useful academic links to add to all of this: http://itlab.uta.edu/sharma/ - Sharma is one of the originators of ECA technology reseach (see HiPAC) ...
Hi, Mark! Nice site, thanks for putting this together for the community. I notice that you left out iSpheres from your line-up of CEP companies. Here is some...
Updated the www.eventstreamprocessing.com. Check it out. 1. Steve - added the links you suggested, good stuff. 2. I think I'll add a larger section on...
To all commercial event processing people out there: Listen up! We need to develop more explanatory examples of event processing, both simple and complex. This...
Steve - can you describe what you envision as the "application use case" for pi-calculus as it might be applied to CEP? - Mark ... science ... record ... On my...
