It is completely standards-based, using RDF as its data exchange model and ZeroConf for resource discovery. It supports a knowledge-centric model of interaction where clients' actions are driven by queries and triggers about the context of the system. It uses gossiping to maintain a consistent state across a distributed data structure, which maximises robustness and scalability and avoids many problems with hot-spots and hot-paths in communications. Finally, it treats all information sources uniformly as sensors acting as inputs to uncertain reasoning algorithms.}, keywords = {construct, middleware, pervasive computing, ubiquitous computing}, ISBN = {1-4244-0667-6}, author = {Simon Dobson and Paddy Nixon and Lorcan Coyle and Steve Neely and Graeme Stevenson and Graham Williamson} }
