Towards Scalable Data Space Interoperability and Federation
conference proceedings
The need for data sharing is growing. A major and growing part of that need will be as sociated with sharing of data across the community borders of individual data sharing initiatives or data spaces. Therefore, the need for an approach for scalable interoperability and federation of data spaces is (rapidly) emerging. This data sharing use cases which are not confined to specific data sharing communities, have two different origins: - use cases to support (static or streaming) data sharing across sectoral regional data sharing initiatives or data spaces, and - use cases to support the new data sharing application areas such as Digital Product Passports (DPPs), Digital Twins (DTs), Privacy Enhancing Technologies (PETs) and event-driven smart contracting approaches. The investments are considerable to develop mutually interoperable and federated data spaces to support such cross-community use cases. Additionally, they can have substantial lead times, especially as interoperability spans multiple levels: governance, legal, semantic and technical. Moreover, building federation in a bilateral manner is not expected to be scalable when large-scale federation is needed, with many cross-cutting use cases. Therefore, in this discussion paper we propose an (alternative) approach for large-scale interoperability and federation of data sharing initiatives and data spaces, enabled by recently developed data space standards. The goal is to initiate discussion with the EU Data Space Research and Development communities to jointly work on scalable interoperability and federation of data spaces.
