The "Data Spaces and IoT Solutions" department at Fraunhofer IIS focuses on solutions that enable data sovereignty and data interoperability. It is no longer just functioning individual systems that are critical to success, but also the effective use of data within an organization and beyond its borders in the partner network. At the stand, we will be presenting a lightweight implementation of the digital product passport, which will be mandatory from 2027. We will also show what we mean by "Talk to your data".
