Re: [soa-rm] On POAs and SOAs

[Duane Nickull <dnickull@adobe.com>]

My personal thoughts on this are that we should be part of a layered 
approach.  We should just stick to SOA, perhaps with a non-normative 
note that explains the relationship that SOA concepts may be "part of" a 
POA.  The reasoning is as follows:

1. If we explicitly associate SOA with POA, we would probably have to 
consider other things that SOA can be used within.  This may be a 
pandora's box since POA is not the only other architectural paradigm 
associated with SOA (Even driven architectures, client-server 
architectures, distributed system architectures, component based 
architecture, etc.)

2.  POA should probably be defined as a POA Reference Model outside of 
the SOA RM.

3. It is not in our charter to tackle POA.

4. POA directly is probably not a core element of SOA, although many SOA 
implementations will be used as part of a POA environment.  The main 
implications for SOA is that conceptually, services may need to be 
robust enough to include the items that POA would demand of it.  This is 
very concrete thinking however.  Must stay abstract.
