A semantic interoperability architecture for Internet of Things data sharing and computing

The Internet of Things lacks standardized mechanisms for discovering new and changing knowledge. While vendors may have the ability to build applications for their own devices, this typically does not enable open communication and sharing of data and knowledge. This document describes an architecture that combines information and data models with ontologies to provide an extensible semantic interoperability layer. This ensures that the meaning of terms and objects in one device or system are not lost or altered when they are exchanged and used by other devices or systems.
