The research activity in the IoT field caused a proliferation of information brokers with different features and targeted at different information abstraction levels. The OSGI Semantic Information Broker (SIB) is a portable and extendable solution for providing an IoT system with semantic support, a publish subscribe paradigm, and expressive primitives for information modeling. In this chapter the authors explain the main reasons for defining a new SIB version, substituting the previously used RedSIB, its main features and comparative evaluation against both ad hoc and standard benchmarks. Furthermore, recently defined primitives and experimental work on the portability to mobile devices and resiliency are proposed and discussed.
