A (somewhat) radical proposal

[Frank McCabe <frank.mccabe@us.fujitsu.com>]

One of the recent ideas to surface in the RM was the concept of  
visibility.

I happen to really like this idea because:

a. it is nice and abstract, without an a priori tendency to  
implementation
b. it characterizes (for me at least) the essential requirement that  
for a service provider and consumer to interact they must be able to  
'see' each other
c. it covers much more than simply description: visibility is a core  
perception

On the other hand, I think that this now makes the section on  
discoverability somewhat out of key. For one thing, despite our best  
efforts, we have not been able to take the implementation aspects out  
of discoverability.

I think that the core reason for this is that discover is an action  
verb, and visibility is a predicate.

I propose to refactor the section on discoverability and focus on  
visibility.

Comments?
