Two more points from the discussion. 1) ultimately, I think that it will be possible to map the ws-chor metamodel to the pi-calculus metamodel (since pretty much all message exchange can be modeled with pi). As a result, one can view ws-chor metamodel as syntactic sugar as it was expressed in the call, but this sugar also helps reducing the need for PhD to write chor-definitions. 2) Would it be a good time to start collecting ws-chor metamodel elements (e.g. role, MEPs, ...). I know we are not done yet through the requirements, that might help people formulate more requirements (e.g. if we have role, we need to define a binding one way or another, ...) I could volunteer for that task.
