an accidental finding

["Mike Poulin" <mpoulin@usa.com>]

Hi All,

I was working on prposal for the EU project on Choreofepahy research and accidentally found a reference (http://organizational-economics.blogspot.com/2011/03/soa-orchestration-and-choreography.html) to OASIS Reference Architecture for Service Oriented Architecture Version 1.0, Public Review Draft 1, 23 April 2008, p. 71, particularly to the definition of Choreography:

A technique used to characterize and to compose service-oriented business collaborations based on ordered message exchanges between peer entities in order to achieve a common business goal.

This is a good news but...

From the recearch where I am participating with a group of univercity professors I know that ordered message exchanges is very narrowed and oversimplified category of choreographies while much more common, especially for independent services, is pre-defined but not ordered message exchanges (called concurrent messages in the choreography behaviour modelling) where more than one message may be sent/received in any choreography state. Also, choreography can define a chain of actions that to be taken in response to certain external events. However, there is no any order of event is unticipated and collections of all related messages cannot be ordered in principle.

Thus, our definition is not generally correct. We need to put more thoughts into it, IMO.

Thanks,
- Michael

Subject: [soa-rm-ra] latest issues spreadsheet

All,

 

 

 

 

 

Attached is the latest slicing and dicing of the issues spreadsheet.  I sorted the issues into different tabs, with each comment being copies to

 

 

 

 

 

adjudication accepted (147 comments): this is just waiting for necessary changes to be done in document

 

 

 

 

 

details to be worked (14 comments): seem to agree in concept but details need to be worked.

 

 

 

 

 

nontrivial work (40 comments): some disagreement remains

 

 

 

 

 

awaiting submitter (97 comments): submitter hasn’t explicitly responded

 

 

 

 

 

complete (1 comment): no further action necessary

 

 

 

 

 

Note, about 60 of these are some degree of accept or a duplicate but submitter hasn’t explicitly responded.  I need to send out a few reminder emails, but everyone should look through these to see where an entry from you can help clear this tab.

 

 

 

 

 

Sorry for the late delivery.  I’ll be calling in shortly.

 

 

 

 

 

Ken
