CFP --- (Data Semantics) (Database Technologies for the Semantic Web) (Semantic Interoperability) (Searching and Querying) User Interfaces Visualization and modelling Our features ------------ (Storm) RDF Views, F+C Loom Fenfire Prospect -------- Making applications in the desktop/PDA interoperate with RDF Handling inferences and composite graphs with our tools Downloading remote web resources, combining them with personal data, visualizing them as buoys in application tools. Waffle ------ We talk about progressive software engeneering technology used for novel mobile hypertextual Semantic Web applications. We have developed a platform for advanced methodological user interfaces. Experience has shown that our technology can keep up with high demands on usability and human-computer interaction by semantic RDF interoperability techniques. We hope that our approach will further the vision of the Semantic Web. Keywords: Semantic Web, User Interfaces, Usability, Progressive Technology, RDF, interop
