Abstract

This paper presents a model of context information data source structuralization, having in mind requirements of Ambient Networks applications. The proposed solution extends the ContextWare architecture, which is a general framework for context information dissemination. It assumes that the transfer of context information which represents a temporal state of sensors is accompanied by semantic information. This is a key concept in achieving true interoperability between heterogeneous system domains in mobile applications. A system for semi-automatic generation of data sources in the form of Web Services wrapping the sensors is presented. The input data of this system consists of information about sensors and an ontology describing their semantics. A proposed notation, describing the mapping of values from sensors to the ontology used in the Ambient Networks project, was employed at this stage. The outcome of the system consists of a Web Service which exposes data and semantics of context information.
