Conclusion
- OWL-S is more complex than WSDL.
- OWL-S gives a lot more details about how a process is
composed of other process, what sequence they must execute,
etc.
- It's processes are akin to AI-planning operators.
- Just-in-time service composition will be much more likely if
services are described using OWL-S. Unfortunately that will
require extra effort on the programmer's part (WSDL can be
generated automatically).
- OWL-S is sits righ between web-services (RPCs over HTTP)
and the Semantic Web vision.
