It is proposed to augment general-purpose middleware solutions for sensors networks by reconfigurable and highly customizable hardware devices, that are capable of manipulating meta data in form of ontologies. Such devices should perform seamless fusion of sensors data and their representation in form of real-world concepts and relationships for purposes of certain single user or a small user??s group. This article offers model-driven design principles for one of such kind of devices, called Ontology Mediator. The architecture and hardware components design are illustrated by example of IRWINNG development framework.
