RIS Synergy establishes data exchange between IT systems of funding organisations and research institutions. The key to this is process optimisation via technical interfaces and well-defined data flows. Aiming to improve data quality and freeing up resources on all sides, RIS Synergy contributes to the sustainable digitisation of the Austrian higher education sector. This poster explains the significant value of persistent identifiers for the RIS Synergy project and the scientific community, and how PIDs work in general.
