Hera is a design methodology that supports the development of Web information systems. It is a model-driven method that distinguishes four steps: data retrieval, application model generation, application model instance generation, and presentation data generation. Data retrieval populates the conceptual model with data. In the application model generation the navigational aspects of the application are specified in the application model. Also, the application model needs to be adapted for different user/channel profiles. In the third step of the Hera method, the application model is populated with the retrieved data. The last step considers the physical aspects of the presentation: the retrieved data wrapped in application logic is translated to different implementation platforms (e.g. HTML, WML, SMIL). Having in mind the advantage of Web application interoperability we chose to implement an experimental prototype for the Hera method using RDF(S), the foundation of the semantic Web.
