Connected ecosystems require to exchange and confirm digitally verifiable mutual trust and that identity is shared automatically among participating federations to establish responsibilities. Such federations can point towards each other using secured generally available public communication channels to exchange digital assets, like Digital Product Passport or Digital Calibration Certificates (DCCs). Given the complexity of information, its unique and differential character comprising different aspects of metrological and industrial requirements, its trustworthy and reliable presentation constitutes a real challenge, especially, if a state authority or a notified body claims an access to the content of a DCC. In our work this challenge is addressed in a framework of verifiable presentations realized by applications of W3C decentralized identifiers and verifiable credentials in a federated international data spaces approach. To realize a verifiable presentation of DCC content on demand between two federations, a trust and identity work package of the Gaia-X along with its new trust management infrastructure (TRAIN) framework has been adapted. The proposed approach is readily scalable, extendable, and accessible to any authorized body and industrial partner or company.
