Every time a Web-based interface is built upon pre-existing data-sources, the result comes often from a difficult and painful process of negotiation between the data manager - who knows the "semantics" of the data to be exposed, but cannot build the UI on his own - and the Web designer - who cares a lot about the presentation and the rendering, but often is not an expert about the content to be displayed. Semantic Web technologies, with their ability to deal with data, their meaning and their representation, can be of great help in those scenarios. In this paper, we present our approach that makes joint use of Web usabil- ity, Web experience, Interaction Design and Semantic Web technologies to develop a Web-application framework calledSTAR:chart, which helps data managers in painlessly building Web-based interfaces upon their data. We introduce the basic concepts, ontologies and software artifacts that make our approach concrete, together with some use case scenarios in which we successfully employed the STAR:chart framework.
