As well as simple planning of IOPE tie up, planners can potentially handle 
many aspects of temporal and resource constraints planning too.

You are correct that issues of how you execute or monitor the execution of 
a workflow against the predicted model of how it will execute as arrive at 
by the planner is a key issue.  A planner by itself can only make sure that 
suitable information is within the plan proposed to allow for rich 
monitoring of IOPE tie up as and other aspects.

We are exploring all of these aspects in our work and we are using our old 
web accessible planner O-Plan and its execution support/replanning 
framework for experiments as an initial guide to the design of the new 
I-Plan that will be a web services composer in the I-X framework.
