This document discusses using FIWARE to enable data sovereignty in manufacturing. It describes a use case where milling machines and coordinate measuring machines (CMM) in a factory share operational data to enable predictive maintenance and zero defects. The FIWARE platform allows the machines to break information silos by sharing select data between manufacturers in a controlled manner. This helps machines improve configurations and maintenance by leveraging each other's data, bringing better service to the factory. Data sovereignty is ensured as manufacturers control what data is shared and how it is used.
