Hi All,

I am trying to understand the semantics of preconditions and effects . 
In one of the papers

Narayanan, S. and McIlraith, S., "Simulation, Verification and Automated 
Composition of Web Services",

I found that preconditions for any service can also be modelled as 
knowledge based apart from physical preconditions.For e.g: agent 
Knows(bookName) for a service like LocateBook. I am interested in 
knowing whether agent can have knowledge based effects as well for e.g: 
agent Knows(ISBN), especially for information providing services.

Any thoughts appreciated.
