In this paper, we present some ideas how to represent, handle, and integrate semantically expressive contextual information Our approach enhances topic maps by more topic and association types and embedded code Our data model is a comprehensive picture combining the knowledge of many context-aware applications It is capable of performing automatic updates of the contained contextual information, computes higher-level information by itself, and routes context events to client applications We present a context-aware front end of a car navigation system that uses our data model.
