Programmation par les utilisateurs finaux : Composition d'applications Web respectueuse de la vie privée

International audienceFacebook, Gmail and Dropbox are only three examples of successful web applications. Each of them provides specif ic functionalities and application composition allows user to extend the range of functionalities they can benefit from. However, they rely on mediation code produced by expert developers. As a result, end users cannot freely compose web applications. They cannot precisely configure their privacy preferences either. These two constrains impair users experience. Our work seeks to deal with this lacks. We propose a model-driven approach which permits end users to specify the composition of their web applicati ons and their privacy preferences. Our approach allows to generate the execution code so that end users do not have to rely on developers. Our work is implemented as a modeling and execution tool. We use our tool to realiz e a real - world compositio

Service Choreographies through a Graphical Notation based on Abstraction Layers and Viewpoints

Best Doctoral Paper AwardInternational audienceOrganizations' business processes become more and more complex and depend on services provided by external organizations. The global viewpoint given by choreography approach is required to better understand, build, survey and optimize complex processes. While existing proposals were made for defining choreographies, it is still difficult to bridge the gap between business process design and implementations. We present choreography with a graphical notation based on metamodeling techniques as abstraction levels and multiple views. This will help us to fully exploit this currently underused concept. Recommendations for addressing identified notation issues are put forward. An empirical experimentation of our work is finally presented bringing about several updates in our proposal
