Supporting Pattern-based Application Authoring for the Semantic Web

The SWAN approach, presented in this paper, addresses the challenging task of developing Semantic Web Applications, i.e., Web applications that fully and effectively exploit and serve the Semantic Web as their operational environment. It is based on the support of two types of models, semantic domain models and conceptual user interface models, as well as on flexible model mappings. The SWAN framework, implementing the SWAN approach, contains tools for pattern-based Web applications authoring. SWAN user interface design patterns reflect frequent dialogue sequences and ease user interface construction as well as interpretation. Furthermore, each SWAN design pattern is associated with mapping constraints, which restrict mappings between user interface and domain model elements.
