David and members of the OWL-S Coalition: Well, the milestones just keep on falling. First SWRL FOL and now OWL-S! I am extremely pleased with the work that the Coalition has done. My own way of thinking about semantic web services is that it is one very important component of a larger vision of agile software and dynamic computing -- a vision that encompasses late binding in data access, software composition, and user interfaces. OWL-S is right now the state of the art in semantically-coherent late binding of web services. OWL-S 1.1 is a huge milestone and a stake in the ground. Congratulations!
