ContextXML: A Data Processing Framework for Ubiquitous Computing

In this paper we propose a framework for developing ubiquitous applications allowing the programmer to concentrate on the application logic. Starting from a lightweight layered system architecture we realize a system by implementing its components using existing technology like JXTA, XML Schema, XPath and XSLT and mapping it to ubiquitous technology like networked sensors. By building a sensor mapping application on top of it we demonstrate the usability and extensibility of our approach.
