HyperCat breaks down data silos by providing a standard API discovery method for IoT solutions. It allows devices, sensors and applications to easily interoperate by sharing a common catalog of metadata. This catalog provides a unique entry point and associates descriptive metadata with the URI of each resource. By checking the catalog, applications can discover what data is available and how to access it in a standardized way without prior knowledge of the underlying APIs. This approach creates higher value for industry and smart cities by enabling data and systems integration across proprietary platforms and devices.
