Semantical Descriptions of Models for Web Design

The use of semantic web languages brings a number of advantages for web engineering methodologies. In this paper we present how in the Hera methodology the design models benefit from description in semantic web languages. We describe how the important models are expressed and how the corresponding meta-models are defined. This is illustrated for the Application Model that specifies the hypermedia navigation over the content in the application, and do so for both the static and dynamic cases. With the support of the dynamics, particularly the interaction of the user with the generated hypermedia presentation, we extend the possibilities to specify the design of a new generation of web applications.
