This report outlines the high-level plan for the RDA TIGER project to engage with European National Networks, and describes activities that have taken place at the time of writing, as well as those still being planned. The deliverable defines European National Networks, identifies key stakeholders within those networks, and outlines how national and regional RDA communities have been involved in engaging the European community with RDA TIGER-supported Working Groups, and the RDA more broadly. Finally, this document presents the next steps in continuing to engage European National Networks, both within the lifetime of the RDA TIGER project and beyond.
