Subject: Re: [soa-rm] Groups - Generic SOA-RM Boot Camp(SOAReferenceModel-Generic-rev1_05-03.ppt) uploaded


These are good points we need to understand.  Can I ask for 
clarification on a few points.

(1) What is your definition of "distributed"?  This will probably be 
important to reach consensus on in our TC.  I googled "define: 
distributed system" and found these definitions:

Paraphrased:  Distributed System:  an aggregation of functionality from 
several computing entities to collaboratively run a computational task 
in a transparent and coherent way, so that they appear as a single, 
centralized system.

Some of the definitions talked specifically about being distributed on a 
network (not good for RM).  The physical separation aspect is not 
something I am clear about WRT being distributed.  Can a chip 
hyperthread two processes and aggregate those at a higher level to 
appear as an opaque computational task?  Perhaps distributed means 
logical separation?  Not sure. 

(2)  Even though we have not made a decision WRT BPM in the RM, do you 
think we could use a more abstract term for it such as "Management" or 
"Process Management"?  This is primarily in recognition of the fact that 
not all SOA's are built for businesses.  The concept can be added to our 
glossary and will need to be defined.  I also used google to find some 
starter suggestions.  I paraphrased several as:

Process Management "..a multi-layered approach to the orchestration of 
lower activities, which produces a result for a given customer at a 
higher level."

Would this work for folks?  Comments?

>(1) I think many of us are scoping the work too narrowly: a "services RM" does not solve what I (at least) need, which is a "services-oriented distributed application" reference model. I had always assumed that when people said "SOA" they meant the latter.  This draft seems to define the former.
>(2)  I don't think the RM should necessarily be limited to elements that are mandatory in all implementations.  You suggest a formulation that avoids this for security (i.e, null security policy is a security policy); Rebecka used a similar device in observing that all mechanisms in a software environment can be defined as services and therefore we might not need to include any particular "SOA infrastructure" services separately in our RM.  I would prefer to be explicit in getting a maximum set of elements on the table (BPM for example) and then coming back later to refactor or simplify the model. Otherwise we may end up with an elegantly simple but trivial product, meaning one that does not provide any useful guidance to architects.
