Subject: Point of Action

It is pretty early days in the RA work. However, we have identified  
at least one concept that might be considered for the RM. This should  
go in section 3.2.3 (Real World Effect).

Point of Action

The time and location where a capability is applied by a service  
provider in reaction to an interaction between the service provider  
and consumer. The point of action is often internal to the service  
provider but represents the locus of the provider's response to the  
consumer in actually applying its capabilities (and analogously, the  
service consumer may also have points of action).

The point of action is a fulcrum for many aspects of service,  
including the management of services, policy enforcement, and  
achieving the real world effect.


On re-reading the RM, I realize that there were analogous concepts  
associated with policies: Policy Decision Point and Policy  
Enforcement Point that have been dropped (they were present in an  
earlier draft).

It is a little early to be certain whether we will need these  
concepts in the RA, but I am fairly confident that we will. The issue  
for me is whether they also belong in the RM.
