Global IoT services (GIoTS) are combining locally available IoT resources with cloud-based services. They are targeting world-wide services. GIoTS require interoperability between the locally installed heterogeneous IoT systems. Semantic processing is an important technology to enable data mediation as well as knowledge-based processing. The authors explain a system architecture for achieving world-wide semantic interoperability using international standards such as oneM2M and the OMA NGSI-9/10 context interfaces.
