The question is  how does one decide which IOPEs to include in the Profile and to what extent, and to which IOPEs to map it in the process model? 

Ideally all the IOPEs that are needed to be specified for any service 
should be included both in the Profile and Process models.  However 
specification of the IOPEs in the Profile may also depends on the 
criteria used by the matchmaker in the sense that some matchmakers may 
use only input -output parameters without considering the preconditions 
and effects. So it basically depends on the algorithm used. There always 
has to be a one-to-one correspondence between the mapping of IOPEs in 
the profile and process model  which can be handled via
"refersTo".

Yes. Intutively this also makes sense as the equivalence between the 
IOPEs of the composite processes and their corresponding atomic 
processes is specified separately anyways  in the DataFlow file. 
Therefore we need to refer to only the Atomic Processes for 
correspondence from the profile.

Hope this helps. Any other thoughts appreciated.
