The Research Data Alliance is an international grassroots organization that brings technologists, developers, and researchers together to jointly develop and adopt data-sharing infrastructure, tools, and practices. RDA working groups tackle some of the thorniest topics facing data science today, including reproducibility, data preservation, interoperability, data citation, and best practices for data repositories. RDA provides useful services to the data-driven research community, including to many grantees supported through the Foundation’s Digital Information Technology program. Funds from this grant provide core operating support to the U.S. regional chapter of the RDA and support efforts to build out the organization’s U.S. administrative infrastructure and grow its membership base. Funded activities over the next three years include the production of reports detailing RDA data sharing recommendations, member outreach, creation of adoption case studies for RDA products and services, trainings, annual stakeholder meetings, and the development of a long term business plan for independent sustainability.
