Digital data repositories, data archives or data centres accept, preserve and disseminate research data, often for a given community. Repositories may be organised by subject (e.g. structural chemistry data, gene sequence data, social science data) or by organisation such as a research funder.
Research data are typically submitted to the repository by the data creator or owner. The data repository then takes responsibility for preserving the data, managing any access restrictions and making information about the data (metadata) discoverable.
