Hi All,

Keeping aside the "web" part, I am interested in understanding the 
semantics of the word "service". Within the web service world, what is 
the lowest level of granularity a service can have. What would be the 
most appropriate definition for the basic building block from which 
bigger units can be composed.  Services communicate via sending and 
receiving messages. Can communication primitives also be classified as 
services i.e in this context is it appropriate to consider the operation 
of sending and receiving as services themselves and can they be modelled 
as such ? In the WS-CDL specification, there are primitives like 
"activities" and "Interaction"
can these be considered as services i.e can a one -way or 
request-response interaction be classified as a service
