My contribution: Challenges Coordination/Correlation of instances Communication among diffrent technologies Coordination/Correlation of browsers/users Coordination/Correlation inter-page Creation of the framework BPEL process and UI components are not compatible Data from a page (master) to another one (slave) of the same application Multiple instances of the same application Starting from the model description (BPEL-UI) create and deploy the (distributed) framework for the communication

- 38. Possible uses of MarcoFlow Orchestration of distribuited UI components & services Visual UI components plus standard web services User-event-based application When the application is managed by events generated by the users Workflow-based applications When the process is thought in a workflow fashion with user interaction Complex mashups When the logic of the process is too complex for a standard mashup tool Multi-page coordination When more than one page is needed and the pages have to be coordinated Fields Health, Office, Factory , Admin...
