The ability to automatically compose Web Services is critical for realising  more complex functionalities.  Several proposals to use automated planning to deal with the problem of service composition have been recently made.

We introduce a language for expressing extended goals, equipped with temporal constructs, maintainability properties, and an explicit distinction between sensing and achievement goals, in order to avoid undesirable situations.
