This guide was created to help researchers locate available resources for data management and sharing.

What are data repositories?

Data repositories are platforms where researchers deposit data generated in the first stages of research projects, review datasets, and share commentaries, assessments and interpretations. Repositories also are being integrated into the middle of research projects by providing software tools. For example, digital tools can be used to discover, analyze and visualize datasets through mining text, images, graphics, and numeric and geospatial data. Furthermore, digital repositories can help researchers manage primary data and secondary information produced when researchers share data and methodologies.
