I am trying to model atomic services in DAML-S (for the moment). I would
appreciate a bit of help to understand how DAML-S is to be applied. A simple
service like P (which corresponds to an action in FIPA SL) with input x, and
output y if execution of P is successful and z if execution of P is
un-successful (a kind of error message). Would I be correct to model it as
follows :

P is an atomic process,
P has an input x
P has a conditional output y with the condition (execution-successful)
P has a conditional output z with the condition (not execution-successful).

Also a related issue: how does this process description map into a service
profile? Will the service profile have one input and two outputs? Do we need
to have conditional outputs in the profile models? Currently, the profile
model only has output parameters and not conditional outputs, while the
process model only allows conditional outputs. As I understand, once a
process model exist, service profiles can be derived automatically. How do
the conditional outputs map into output parameters in the profile model.

With many thanks
