GRIIDC, a multidisciplinary data repository, has been providing data management and archiving services since 2011. GRIIDC partners with national and regional funding agencies that value quality data management and long-term preservation of scientific data to assist funded researchers with data sharing goals. Since GRIIDC’s inception, data management standards, technology, data sharing requirements, and researchers’ attitudes towards sharing data have changed. As the climate of open data has evolved, collaborations between funding agencies, researchers, and data repositories have become more important. Funding agencies and journals that require open data rely on repositories to support these goals and adapt to new standards. A major shift has been the adoption of FAIR principles, ensuring data are Findable, Accessible, Interoperable, and Reusable; another is the adoption of TRUST principles for data repositories, focusing on Transparency, Responsibility, User focus, Sustainability, and Technology. These principles direct GRIIDC data curation procedures, software development, and researcher training. Curation involves verifying that data are organized, well-documented, and in non-proprietary formats. GRIIDC training materials, such as guidance documents and webinar presentations, are regularly adapted to adhere to these guidelines, streamline the submission and curation process, and ensure researchers are prepared for data sharing. In adapting to an ever-changing open data climate, challenges arise such as recursively improving metadata attributes, longer curation time for datasets, additional exchange with researchers to manage data, and growing storage needs for larger and more complex datasets. Collaboration and support from funding agencies is vital to strong data sharing policies and proper data management techniques. Data repositories, working in tandem with funding agencies, researchers, and journals, have a significant role as data stewards in the changing landscape of open science.
