Re: [soa-rm] core nature of a Service-Oriented Architecture[was: Security]

[Rex Brooks <rexb@starbourne.com>]

Hi Monica,

Several of the position papers/treatises provide analyses of the core 
model, so I was just reminding us that we were 'maybe' getting a bit 
far afield, and that is only with a heavily circumscribed 'maybe' 
since we may in fact decide that authentication, authorization, 
certification, etc may be abstract enough and important enough to 
include, but if we do, it will certainly inspire similar specificity, 
and, no doubt, similar discussions around messaging/communication, 
which has already been taken up, and other protocol-specific 
discussions about what is in-band and in-scope or out-of-band and 
out-of-scope, and whether or not we should address those 
infrastructure-level questions. I started out wanting to work from 
the concrete, bottom-up to the abstract, and I'm still sticking with 
that , but I am seeing the wisdom in requiring our final work, once 
well grounded, to stay as abstract as we can make it, and define the 
areas in which we can, perhaps, inspire more detailed and specific 
models to be built to the general framework of the Reference Model.

Ciao,
Rex
