Data Repository

A data repository can be defined as a place that holds data, makes data available to use, and organizes data in a logical manner. A data repository may also be defined as an appropriate, subject-specific location where researchers can submit their data. Data repositories may have specific requirements concerning subject or research domain; data re-use and access; file format and data structure; and the types of metadata that can be used. Librarians can assist researchers in finding a data repository by evaluating and recommending subject-specific repositories that would be best suited to hold or find and use biomedical research data. Many data repositories have restrictions on who can deposit data into them based on funding, academic qualification, and quality of data. There are, however, a number of data repositories that are classified as "open"; and as a result are essentially open to receiving data from anyone. Institutional repositories may accept data or an institution may have a separate data repository.
