On building location aware applications using an open platform based on the NEXUS Augmented World Model

摘要

How should the World Wide Web look like if it were for location-based information? And how would mobile, spatially aware applications deal with such a platform? In this paper we present the neXus Augmented World Model, an object oriented data model which plays a major role in an open framework for both providers of location-based information and new kinds of applications: the neXus platform. We illustrate the usability of the model with several sample applications and show the extensibility of this framework. At last we present a stepwise approach for building spatially aware applications in this environment.
