Yet Another BPEL Extension for User Interactions

Adaptable UI for Web Service Composition: A Model-Driven Approach

“…So far, we have reviewed the literature about the users interactions and Web services. We have already proposed a BPEL extension able to modelize all types of user interactions within WSC processes, named UI-BPEL meta-model [3]. We have also implemented a design tool that is dedicated to edit a WSC conform to our UI-BPEL meta-model.…”

UsiWSC: Framework for Supporting an Interactive Web Service Composition

“…This tool is developed as an Eclipse plug-in based on the Eclipse BPEL Designer [4]. The UI-BPEL specification enables the description of different user interactions by introducing new BPEL elements [2]: (1) a new set of BPEL activities (DataInputUI, DataOutputUI, DataSelectionUI ) to express different user data interactions; (2) a new type of BPEL events (InteractionEventUI ) to express the interaction event; (3) an extension of the BPEL's Pick and Scope activities that supports the new InteractionEventUI ; (4) a new activity attribute UserRole that specifies the role that is assigned to a data interaction activity.…”

“…In this work, we propose the UsiWSC framework (Usable uSer Interface for Web Service Composition) that supports the design, the deployment and the execution of an interactive Web service composition. At design time, an interactive composition is defined based on an UI-BPEL extension [2] that supports the specification of user roles and the different types of user interactions. At deployment time, abstract user interfaces and BPEL are derived from UI-BPEL.…”
