FREYA is a 3-year project funded by the European Commission under the Horizon 2020 programme. The project aims to build the infrastructure for persistent identifiers as a core component of open science, in the EU and globally. FREYA will improve discovery, navigation, retrieval, and access of research resources. New provenance services will enable researchers to better evaluate data and make the scientific record more complete, reliable, and traceable. By engaging with the global community through the Research Data Alliance and other research infrastructures, we work together to realise the vision of fully and effectively accessible data. FREYA follows on from the successful THOR project.
