Re: [soa-rm] Diagram

Duane:
  It is not the interaction that results in a real world effect.
  It is the use of the capability that does.
  Also I don't think its quite accurate to say that the link between  
interaction and service is exchange. You interact with a service by  
exchanging information.
  The execution context includes *everything* needed to support  
interaction.
  It is not right to say that visibility = policy+service+description  
(as implied by the nesting. We currently state that  
visibility=awareness+willingness+reachability.

P.S. I gave a talk about the RM to OMG yesterday. Went down very  
well. People like the simplicity.
P.P.S. Concept maps are very flexible. That is both an advantage and  
a risk :)


  Of course, what is not captured is how the RWE™ itself is modeled...
