This dissertation presents how a model driven development architecture and environment framework to support Web application development are being developed using SHDM/OOHDM as development methods. The models are described through graphical diagrams that are processed by the environment. The application interface is also produced using models, and the interface produced is defined by concrete interface ontologies, specified in RDFS, that maps the concrete widgets to some target technology such as ASP.Net and XAML. The main purpose is to ease the development of a web application using Visual Studio .Net 2005 as an IDE and SHDM as the development method, allowing the application architect to focus on the application modeling. SHDM .Net generates a complete runnable application; also producing domain- specific languages for each application modeled, resulting in a programming model much more concise and natural. The main feature of SHDM .Net is the integration between the analysis and development phases of a project.
