Hypermedia design methods have been proposed for the development of hypermedia and web applications. Nowadays, we face up to another challenge, the Semantic Web, in order to represent web resources in a structured, logical and semantic way. Therefore, hypermedia design methods will have to provide semantic contents and contextual information about application domain during the development process of web applications. In this paper, we propose to accomplish that including ontologies within the conceptual modeling of hypermedia applications.
