27. Mycontribution: Challenges
Communicationamongdiffrenttechnologies
BPEL process and UI components are not compatible
Coordination/Correlation of browsers/users
Coordination/Correlation inter-page
Data from a page (master) toanotherone(slave) of the sameapplication
Coordination/Correlation ofinstances
Multiple instancesof the sameapplication
Creation of the framework
Starting from the model description (BPEL-UI) create and deploy
the (distributed) framework for the communication

The MarcoFlow team
45. 46. Otherfeatures
Join a running application instance
Reopening a page with an old idSession the data present in the buffer are shown to the user
Time machine
It is possible to navigate among the data passed inside the buffer.
The user can view the history of the application.
47. Possible uses of MarcoFlow
Workflow-based applications
When the process is thought in a workflowfashion with user interaction
User-event-basedapplication
When the application is managed by events generated by the users
Orchestrationofdistribuited UI components & services
Visual UI components plus standard web services
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...
