This document is the final policy brief of the RDA TIGER project, building on recommendations and policy impact areas identified in the first brief published in 2023. It outlines the contribution of the RDA TIGER project, and given the nature of the project, the Research Data Alliance (RDA) community of 16,000 members globally, to the EOSC Strategic Research and Innovation Agenda (SRIA). The RDA TIGER project provided a suite of support services to RDA Working Groups (WGs) that concretely align, harmonise and standardise Open Science developments and technologies globally, with a specific focus on WGs that contribute to the EOSC and broader European ecosystem. Through the supported WGs and their careful selection based on specific criteria that consider their demonstrable alignment with the SRIA, the project made direct contributions to the European Open Science Cloud Partnership, while also supporting the international engagement and alignment of policies, technologies, methodologies, practices and other outputs relating to EOSC and European Open Science developments.
