The Internet of Things (IoT) is considered as a potential technology for solving a wide range of social problems and providing services in a variety of fields such as smart homes, smart factories, healthcare and the public sector by allowing various devices to access and interact with each other through the Internet. However, proprietary IoT platforms which are not able to communicate with other platforms because of the different data model and data access mechanisms cause an interoperability problem. In order to resolve the interoperability issue, Korea and the European Union started a joint ICT R&D program called Worldwide Interoperability for Semantics Internet of Thing (Wise-IoT) project to develop a novel architecture that supports interworking between various IoT platforms using semantics. The developed interworking technologies are expected to be used in innovative IoT services which use IoT devices and data distributed all around the world. In this paper, we analyze IoT standards and platforms used in Europe and Korea and introduce the Wise-IoT architecture that interoperates various IoT standards such as mainly oneM2M and FIWARE. In addition, we introduce testbeds and use cases that use the semantics interworking technologies from Wise-IoT to see the feasibility of supporting global IoT services (GIoTs).
