Construct differs from other pervasive systems platforms in number of key respects. It is completely standards-based, using RDF as its data exchange model and CeroConf 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 its inputs to uncertain reasoning algorithms.
