Where should I store data for long-term preservation and access?

Take action

  • Identify data repositories that accept data from the specific domain in which they were produced
  • Determine if the selected repository has been certified as a trustworthy repository



Databib is a searchable catalog / registry / directory / bibliography of research data repositories.

OpenDOAR is an authoritative directory of academic open access repositories. Each OpenDOAR repository has been visited by project staff to check the information that is recorded here. This in-depth approach does not rely on automated analysis and gives a quality-controlled list of repositories.

The goal of is to create a global registry of research data repositories. The registry will cover research data repositories from different academic disciplines. will present repositories for the permanent storage and access of data sets to researchers, funding bodies, publishers and scholarly institutions. In the course of this mission aims to promote a culture of sharing, increased access and better visibility of research data.



  • Nature Video. Scientific Data: Helping You Publish, Discover and Reuse Research Data. Nature Publishing Group, 2013.

Helping you publish, discover and research data. A new open-access, online-only publication for descriptions of scientifically valuable datasets. It introduces a new type of content called the Data Descriptor, which will combine traditional narrative content with curated, structured descriptions of research data, including detailed methods and technical analyses supporting data quality. Scientific Data will initially focus on the life, biomedical and environmental science communities, but will be open to content from a wide range of scientific disciplines. Publications will be complementary to both traditional research journals and data repositories, and will be designed to foster data sharing and reuse, and ultimately to accelerate scientific discovery.



This document is a technical Recommendation to use as the basis for providing audit and certification of the trustworthiness of digital repositories. It provides a detailed specification of criteria by which digital repositories shall be audited.

Fifteen years after the publication of Preserving Digital Information, we are close to having an international standard that sets out auditable requirements for the various functions of a digital repository, and another that establishes the criteria for organizations that certify those repositories as trustworthy. Many challenging digital preservation issues remain to be addressed, e.g., the best business model for those organizations that serve as trusted digital repositories, appropriate formats for long-term preservation, and the copyright and intellectual property issues associated with migration and emulation. Nonetheless, the presence of [ISO 16363 and ISO 16919] standards for trusted digital repositories marks a significant step forward.

In March 2000 RLG and OCLC began a collaboration to establish attributes of a digital repository for research organizations, building on and incorporating the emerging international standard of the Reference Model for an Open Archival Information System (OAIS). A working group was created to reach consensus on the characteristics and responsibilities of trusted digital repositories for large-scale, heterogeneous collections held by cultural organizations. A draft report was issued in August 2001 and in the extended comment period that followed a variety of interested individuals and organizations around the world contributed numerous thoughtful and helpful suggestions that have been incorporated into this final report.
