MedView is a project that meets the challenges of evidence-based oral medicine by providing a formalisation of clinical examination data and clinical procedures. Tools are provided for knowledge acquisition, knowledge generation, visualisation and analysis of data, and knowledge sharing. The formal declarative model constitutes the main governing principle in MedView, not only in the formalisation of clinical terms and concepts, but in visualisation models and in the design and implementation of individual tools and the system as a whole as well.
