With so much data available, it is not easy to manage it effectively. There is a massive need for solutions to facilitate the collection, sharing, storage, processing, trading and reuse of data. The EU-funded PISTIS project will bring forward a reference federated data sharing/trading and monetisation platform for secure, trusted and controlled exchange and usage of proprietary data assets and data-driven intelligence. It will advance techniques and technologies, such as federated data discovery and sharing, distributed ledger technologies, data non-fungible tokens, AI-driven data quality assessment and monetisation, to build trust among stakeholders and assuage their safety concerns. PISTIS will consider the different data supply and demand perspectives and train stakeholders to evaluate the sustainability of their data sharing strategies.
