The FREYA project has now concluded and has achieved some highly important results for the PID infrastructure.
The conceptual and technical bases of the general PID Graph were established, making concrete the motivating vision of the project that was refined through the creation of a corpus of user stories representing real needs for a rich PID infrsatructure. A production service for the general PID Graph was launched by DataCite in May 2020. FREYA also contributed to the development of PIDs for entities that do not yet have them (or are not yet mature), and created or enhanced a range of PID-based applications in several diverse areas of research, showing the potential of the PID Graph vision.
FREYA has established an excellent track record in communication with stakeholders and communities in the world of PIDs. At an early stage the project’s initial online communication channels were set up in the form of a Twitter channel and website. FREYA has been represented at many high-profile events including RDA Plenary Meetings, PIDapalooza (a major annual event dedicated to PIDs) and many conferences. An active group of FREYA Ambassadors was established. A major development was the launch of pidforum.org a website for all kinds of information exchange about PIDs, under the aegis of FREYA.
Regarding the PID Commons, the landscape changed rapidly as the FREYA project progressed, and especially as EOSC gathered momentum and its structures and procedures evolved. FREYA's work on sustainability began with a comprehensive review of relevant existing material to inform the planning, and examined the "what", "who" and "how" of sustainability. In the final year, an important study was conducted of the potential for a "PID Alliance" of stakeholders, which could form the kernel of the PID Commons. FREYA also contributed to EOSC activities including the formulation of the EOSC PID policy.
Fruitful collaboration took place with other EOSC-building projects, EOSC-hub and OpenAIRE Advance.
