CEF eDelivery is expanding successfully into a large and growing number of sectors. As its use increases, its application areas diversify. The International Data Spaces Association aims to bring together business and research organisations to take an active part in designing a trustworthy architecture for the data economy. In June 2019, the IDSA held its second summit in Frankfurt. The CEF eDelivery team participated to learn more about IDSA and to the use cases and pilots in which the architecture is being used.
