Re: [soa-rm] Groups - Rough notes taken during the last ebSOA meeting. (ebSOA-Elements.pdf) uploaded

Might it not be good to start by listing the capabilities an SOA 
enables?  For example, an SOA enables a set of distributed resources (both 
data and processing resources) to be assembled to accomplish a task defined 
independently from the SOA or its implementation.  Questions that follow are
- how do you know the resources exist? (seems to imply some catalog mechanism)
- how do you know what the resources provide?
- how do you understand the resource, assuming it may use a vocabulary that 
differs with (although it may overlap) yours?
- how do you ascertain the quality of the resource?
- how do you decide if the resource is useful in satisfying your task?
- if the resource may be useful, how do you access/invoke it?
- how do you use a given resource consistently with other resources?
- how do you capture what resources you used, in what order, and the 
rationale for their choice and use?

Now, what do our answers to these imply about the architecture?  Everything 
tends to be described in tiers of functionality, e.g. (my favorites) user 
interface layer, service composition/meditation layer, resource layer, and 
then there is the question of are there certain types of services, e.g. 
discovery, that are so intrinsically part of the concept that these need to 
be specifically called out?

Let the fun begin!
