ADVANCEMENTS UNDER THE moniker of the Internet of Things (IoT) allow things to network and become the primary producers of data in the Internet. IoT makes the state and interactions of real-world available to Web applications and information systems with minimal latency and omplexity. By enabling massive telemetry and individual addressing of “things,” the IoT offers three prominent benefits: spatial and temporal traceability of individual realworld objects for thief prevention, counterfeit product detection and food safety via accessing their pedigree;enabling ambient data collection and analytics for optimizing crop planning, enabling telemedicine and assisted living; and supporting real-time reactive systems such as smart building, automatic logistics and self-driving, networked cars.11 Realizing these benefits requires the ability to discover and resolve queries for contents in the IoT.
