EUD for semantic orchestration of web services in workflow management systems

This paper presents a Task Management System based on a Web service architecture on which a network of software environments is developed. The environments are devoted to support end users in performing End-User Development activities and in exploiting their knowledge and expertise about their business processes. TMS network allows end users, who are experts of a specific domain and work together in the same organization, to design a workflow through visual composition of Web services, to visually validate its execution and to execute it at use time. In particular, the implementation of the TMS Editor, i.e. the environment dedicated to the workflow designer, is presented. The TMS Editor is used to transform the task analysis documents prepared by domain experts into a description of the workflow in terms of the components needed and the relationships among them. The components retrieved and used by the workflow designer are Web services that are available in remote or local repositories. The TMS was presented in its first stage of design and development at EUD4Services 2010.
