Web Information Systems (WIS) present up-to-date information on the Web based on data coming from heterogeneous sources. In previous work the Hera methodology was developed to support the design of a WIS. In this paper we target the design of an intelligent WIS. For this reason the Hera methodology is extended with two kinds of hypermedia presentation adaptation: adaptability based on a profile storing device capabilities and user preferences, and adaptivity based on a user model storing the user browsing history. While adaptability is considered to be static, i.e. the presentation is fixed before the browsing starts, adaptivity is dynamic, i.e. the presentation changes while the user is browsing it. The models used in Hera and their adaptation aspects are specified in RDF(S), a flexible Web metadata language designed to support the Semantic Web.
