The document discusses the European Commission's investments and activities related to Internet of Things (IoT) standardization and interoperability. It outlines the H2020 and AIOTI approaches, which focus on establishing common standards to enable data sharing across IoT systems from sensors to AI. Large scale pilots and projects are used to test interoperability in different application domains like agriculture, manufacturing, healthcare and more. The AIOTI working groups contribute to these efforts by developing recommendations on IoT reference architectures, identifiers, security, and semantic interoperability.
