Web service technologies have specificities that must be accounted for at the design level. The first part of this paper presents a web service design language WS-UML that is a UML profile. WS-UML extends UML with graphical annotations to express the specific concepts of web services, e.g., composition, security, location, trace of execution. The second part of this paper presents a meta-model describing the essential elements of web services. Finally, the paper illustrates the usefulness of the WS-UML notation using a Tourist information service example.
