Metadata based approaches have been widely proposed to integrate distributed databases that allow the users to take advantage from all the information stored on disparate/distributed databases relevant for their activities. Aim of the paper is to illustrate the implementation architecture of a metropolitan information system, called Wi-City, able to provide real time location based services (LBSs) to support effectively the mobile users by exploiting all the information publicly available on heterogeneous systems. The paradigm Model-View-Controller (MVC) is adopted to develop user centered LBSs. Advantages and future works of using MVC for supporting mobile users are discussed by illustrating the main functions and user interface of Wi-City.
