An ontology-based representation of information about a domain is flexible enough to support different strategies in presenting the information. In this paper, we present two applications for creating interactive presentations in a cultural heritage domain, that share the same database of informative units and the same representation of the domain, encoded in a light-weight ontology. An application for drama-based guided tours assembles the informative units in a location-aware fashion, by exploiting the structure of the ontology to enforce the notion of discourse focusing in the generated presentation. A browsing-based application for accessing the informative units supports semantic search, consulting the ontology to suggest modifications of the user's search to circumscribe or enlarge the result sets.
