Advances in Web of Things for IoT Interoperability

It is widely acknowledged that the current Internet of Things (IoT) ecosystem is highly fragmented. The Web of Things (WoT) aims to counter the fragmentation using the principles of Web, standardized metadata and APIs. This paper describes the recent advances in W3C WoT including its architecture and building blocks. We also highlight an experiment using WoT Thing Description that help achieve interoperability between two IoT systems.
