For them the process layer is clearly on top. On the other hand you could also give an even more service-oriened view on all these layers by considering that all or many of them expose their functionality as service and are managed accordingly. Causality is definitly an important issue, which we subsumed so far in the model integration aspect. Best regards, Wolfgang Dear Nick,

If so why is service not on top? What I could not find in the challenges bullet list was the configuration of a transformation table in which causality between the layers is hard wired for a specific service.
