....proposed in PARIDE is intended to be used as a conceptual tool for effectively designing cooperative applications. With such a respect, it should be possible to represent e Service schemas in a visual notation, and to translate them into implementation technologies. As regards the first issue, in [13] a UML based notation for e Service schemas has been proposed, on the basis of a specific tailoring of the UML Class Diagrams and UML Statechart diagrams. Specifically, stereotypes have been introduced to represent type classes and messages, and rules for specifying relationships among messages ....
....of such information, the Information Manager provide an interface to all the other elements to access and manage it in an uniform and location transparent way. Currently two different prototypes of the Information Manager have been built, the first one more centralized and based on MOF technology [13], the latter completely distributed and based on UDDI technology [27] B. The Orchestration Engines An orchestration engine, deployed on the cooperative gateway of an organization, consists of different components: r the enactor, which contains the control logic for enacting orchestration ....

....will be discussed in the following of this paper. All e Services are compliant to a conceptual component model; each e Service is described through a conceptual specification consisting of a UML Class Diagram for the structural part and of UML Statechart Diagrams for the behavioral aspects [12]. In the class diagram, each class is stereotyped with flat , active and event , to represent respectively structured data, characterized by prop erties attributes only, the main functionalities provided by the e Service, and the events raised reacted to by active classes. The services ....
