A Vocabulary of Confusion

Greg Reemler
Wed, 16 Apr 2008 08:48:20 +0000

The blog post, On Event Processing Agents,*reminds me of a presentation back in March 2006, where TIBCO’s ex-CEP evangelist Tim Bass (now busy working for a conservative business advisory company in Asia and off the blogosphere, as we all know) presented*his keynote, Processing Patterns for Predictive Business, at the first event processing symposium.
In that presentation,*Tim introduced a functional event processing reference architecture*based on the long established*art-and-science of multisensor data fusion (MDSF).***He also highlighted the importance of mapping business requirements for event processing to established processing analytics and engineering patterns.
In addition, Tim*introduced a*new slide (shown below),**”A Vocabulary of Confusion,” by adapting a figure from the Handbook of Multisensor Data Fusion, overlaying the notional overlap (and confusion) of the engineering components of MSDF with CEP and ESP, to illustrate this confusion:
One*idea behind the*slide above, dubbed the “snowman” by Tim, was that there is a wealth of mature and applicable knowledge regarding technical and high functional pre-existing event processing applications*that span many years and multiple disciplines in the art-and-science of MSDF.**** A few emerging event processing communities, vendors and analysts*do not seem to be*leveraging the art-and-science of multiple core engineering disciplines, including well established vocabularies and event processing architectures.**
On Event Processing Agents implies**a “new”*event processing reference architecture with*terms like,**(1) simple event processing**agents for filtering and routing, (2)**mediated event processing agents*for event*enrichment, transformation, validation, complex event processing agents for*pattern detection, and intelligent event processing agents for prediction, decisions.
Frankly, while I generally agree with the concepts, I think the*terms in On Event Processing Agents*tend to add to the confusion because*these*concepts in On Event Processing Agents*are following, almost exactly, the same reference architecture*(and terms)*for MSDF, illustrated again*below to aid the reader.*
Unfortunately, On Event Processing Agents does not reference the prior art:
My*question is*why,**instead of creating and*advocating a seemingly “new vocabulary” and “new event processing theory”, why not leverage the excellent*prior art*over the past 30 years?**
Why not leverage the*deep (very complex) event processing knowledge, well documented and*solving some of the*challenging*CEP/EP*problems we face today, *by some of the top minds in the world?***
Why not*build upon*the knowledge of a mature*pre-existing CEP*community (a community that does not call itself CEP)*that has been building successful operational event processing applications for decades?
Why not move from a seemingly*”not really invented here” approach to “let’s embrace the wealth of knowledge and experience already out there” worldview?
Since March 2006, this question remains unanswered and, in my*opinion,*the Vocabulary of Confusion,**introduced in March 2006 at the first unofficial EPTS party, is*even more relevant today.** Competition is good; *new ideas are good; new perspective are good;*however ignoring 30 years of prior art and not leveraging*critical prior art is not very good, is it?
Frankly speaking, there is more than enough CEP theory in the art-and-science of MSDF.* If we map the prior art*of operational MSDF systems*against existing “CEP platforms” we will*gain*critical knowledge in just how far behind the emerging CEP/EP software vendors are in their understanding of where event processing has been and where the art-and-science is headed.**
Well, enough of blogging for now.** Time to get back to mudane SOA “hearding*cats”*tasks at Techrotech, so I’ll be back*Off The Grid for a while.
