Data sharing refers to the practice of making data available to other research stakeholders, including other investigators, research subjects, and the broader public. Various funding agencies, publishers, and other research institutions mandate data sharing as a means to promote transparency, research reproducibility, and to increase the impact of research data. Data citation and data publication can help ensure that originating researchers receive proper credit for their work.
The Open Science Framework (OSF) is a platform for collaboration and data sharing.
The NIH maintains a list of NIH supported repositories.
