In this paper we discuss issues related to the underlying information infrastructure needed in order to support location services and routing in indoor environments. Location based services are typically encountered in outdoor environments and rely on Geographical Information Systems (GIS) in order to correlate a wealth of data to the present location of a mobile terminal. We discuss the very interesting issue of routing within a building environment. Existing approaches are based exclusively on geometric information and neglect important aspects like semantics bound to building areas and user profiles. Hence, the derived applications do not reach the intelligence level anticipated by modern users. We extend the existing approaches through the introduction of user profiles and the adoption of an ontological framework for handling routing requests. We discuss all the algorithmic background used by the proposed system for resolving this interesting problem of mobile information services.
