I do not see any benefits of choreography in Udi example but coupling R, S1 and S2. Moreover, to have the fixed set of exchange messages between them, none of...
... Not sure what your point is here. The fact that BizTalk uses BPEL as an import/export representation doesn't make it unique - many tools do this....
There is something stopping it: Compiled proxy clients. Also, WS-* is designed to be agnostic of HTTP so it doesn't have a redirection mechanism built-in (that...
What I'm saying is that I worked on a project where we used BPEL fragments as attachments to the content messages to indicate the next stages of the process...
... Business services are responsible for their own state – whether they store it in memory, on disk, or wherever. I assume that you’re referring to the ...
My bad John, I thought that when you said "BPEL is a an orchestration language" that you meant "BPEL is an orchestration language". I'll quit taking you so...
Steve, would it be proper understanding of your splendid example if I say that each participant indicated "the next stages of the process flow" that addressed...
Udi, when i said "bad model", it was not what I meant. The model was, probably, good but it modeled bad business case. That is, it modeled existing business...
... Yes. Or more explicitly indicated the interactions that would help the participants reach the mutual goal. Basically the process would be one of three...
Be nice, Jeff. BPEL may be an "execution" language, but it has a number of shortcomings in terms of its ability to represent business processes. Many vendors...
... I do. Indeed my experience has been that restricting yourself to the main BPEL set, i.e. facing the reality that workflow is a different thing, tends to...
Anne brings up some great points below. BPEL, unfortuneately, was not originally intended for business process serialization. Despite this omission, I tried...

"XTP is highly touted for the financial services industry where it can, for example, help prevent cyber theft by sorting through massive transaction data...
... Perhaps, but this article doesn't seem to make the connections betwen XTP, CEP and SOA. ... Didn't Ranadive (and cohorts) pioneer real-time events some...

The following article is at: http://weblog.infoworld.com/realworldsoa/archives/2008/09/google_chrom e_a.html I'm quite interested in the views of others on the...

<<Speaking at an auto-industry-specific standards group supply-chain workshop this week, my role was to cover the role of SOA in modernizing supply-chain...
... I seem to run into these two all the time. For many, SOA = SOAP. Period. Any discussion to separate the two is derided, with the person trying to note...
It depends if the service is viewed as the technical service, in which case the UI isn't part of it. Or a business service which is providing capabilities to...
Interesting timing of your question Rob. I pose the blog entry Gervas posted from me as a partial response to your question. However, I would be careful...

Sorry for shaking almost dead fish - I have found a few points in Steve's note thta, I think, very important for understanding of dynamic orchestration: 1)...
Fair point. That didn't come across exactly as I had intended. I was focused on making the platform point. I like the characteristic angle of implicit SO...
