Subject: Re: [soa-rm] On POAs and SOAs
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.
