ABSTRACT
This chapter reviews recent trends and challenges on interoperability, discuss physical versus virtual and while addressing technology interoperability challenges in parallel, discusses how, with the growing importance of data understanding and processing, semantic web and their technologies, frameworks and information models can support data interoperability in the design of the Future Internet. Heterogeneity of underlying devices and communication technologies and interoperability in different layers, from communication and seamless integration of devices to interoperability of data generated by the Internet of Things (IoT) resources, is a challenge for expanding generic IoT solutions to a global scale. Semantic interoperability of the IoT data will ensure that data that is provided from different sources and by various providers is unambiguously accessible and process-able across different domains and stakeholders. The key to eternal interoperability is to make the networking of systems agnostic to their specific technological middleware.
