Schemas for IoT interoperability for smart cities

One of the key aspects of smart city ecosystem is enabling easy collection and exchange of data to develop new applications. Providing good, open API's for smart city middleware along with standardising the data schemas will be vital for application and device ecosystem to evolve. In this paper we present the resource catalog component of the middleware along with a framework to develop data schemas for IoT devices. Using data schemas one can provide meta-data which enables effective use of the device data.
