That is true - this is not really an API question and thanks for forwarding it to the appropriate list Bijan. I think you got an idea of what I was after - I guess in simpler terms for now (and I will return with a more elaborate formulation of my query) I am trying to figure out if OWL_S and its constructs can allow the description of elaborate task graphs that represent a set of composite services (each composed of atomic processes) that can also interact between them. For example an application-like description where a composite service A can wait for events from composite service B. I don't think this is the original purpose of OWL-S but would there be a value in adding such extensions to it ?
