XIS - UML Profile for eXtreme Modeling Interactive Systems€€The work presented in this paper is partially funded by FCT (Portuguese Research and Technology Foundation), project POSI/EIA/57642/2004 (Requirements engineering and model-based approaches in the ProjectIT research program).

The first version of the XIS profile addressed the development of interactive systems by defining models oriented only towards how the system should perform tasks. However, issues such as user-interface layouts, or the capture of interaction patterns, were not addressed by the profile, but only by the source-code generation process. This originated systems that, although functional, were considered by end-users as “difficult to use”. In this paper we present the second version of the XIS UML profile, which is now a crucial component of the ProjectIT research project. This profile follows the “separation of concerns” principle by proposing an integrated set of views that address the various issues detected with the previous version of XIS. In addition, this profile also promotes the usage of extreme modeling, by relying on the extensive use of model-to-model transformation templates that are defined to accelerate the model development tasks.
