A data repository is a centralized database or storage system where research data, documents, or other types of information are collected, organized, and stored for future reference or analysis. Researchers can deposit their data in a data repository to make it publicly accessible, shareable, and reusable by other researchers in the field. Data repositories often have specific guidelines for data formatting, metadata descriptions, and access restrictions to ensure that the data is accurate, well-documented, and easily discoverable. Researchers and institutions may also use data repositories to comply with funding agency mandates for data sharing and archiving.
