Actually, I think that an error/fault report is a legitimate RWE!
Perhaps it is not the desired effect... Otherwise if you try to
distinguish successful interactions from unsuccessful ones you are
going to get into an awful tangle.
DN: This may slightly clash with your earlier thoughts on this thread
WRT "It is not the interaction that results in a real world effect. It
is the use of the capability that does." I am not weighed either way
since it requires more thought than my mind is currently capable of ;-)
Again, it is not a question of what needs to be visible. But rather
that visibility is an inherent aspect of SOA.
Visibility may be enhanced by discovery/descriptions etc. but is a
separate concept. For one thing, it is inherently consumer/provider
neutral.
DN: yeah - that is the one concept I had the most trouble with and am
stil not happy. It is kind of like "semantics" - irgundwo and nirgundwo
(everywhere and nowhere in German).
