In this article we present a method for the design and implementation of Web Applications for the Semantic Web. Based on the "Object Oriented Hypermedia Design Method" approach, we used ontology concepts to define an application conceptual model, extending the expressive power of the original method. The navigational model definitions use a query language capable of querying both schema and instances, enabling the specification of flexible access structures. Additionally, we propose the use of faceted access structures to improve the selection of navigational objects organized by multiple criteria. Finally, we present an implementation architecture that allows the direct use of the application specifications when deriving a final application implementation.
