IoT Observatory is a global distributed catalogue of applications and data related to various IoT domains. It supports users from various scientific, administrative and social domains to collaborate, engage and contribute their existing data analytics in a secure way with other users. This can support both academic and industrial domains to create real value of the IoT data in terms of research and economics.
