In January 2007 representatives of four preservation organizations convened at the Center for Research Libraries in Chicago to seek consensus on core criteria for digital preservation repositories, to guide further international efforts on auditing and certifying repositories. The organizations were:
- The Digital Curation Center (U.K) [2]
- DigitalPreservationEurope [3]
- NESTOR (Germany) [4]
- Center for Research Libraries (North America) [5]
The attendees identified what they believed were ten basic characteristics of digital preservation repositories. The key premise underlying these characteristics is that for repositories of all types and sizes preservation activities must be scaled to the needs and means of their respective designated community or communities.
- The repository commits to continuing maintenance of digital objects for identified community/communities.
- Demonstrates organizational fitness (including financial, staffing, and processes) to fulfill its commitment.
- Acquires and maintains requisite contractual and legal rights and fulfills responsibilities.
- Has an effective and efficient policy framework.
- Acquires and ingests digital objects based upon stated criteria that correspond to its commitments and capabilities.
- Maintains/ensures the integrity, authenticity and usability of digital objects it holds over time.
- Creates and maintains requisite metadata about actions taken on digital objects during preservation as well as about the relevant production, access support, and usage process contexts before preservation.
- Fulfills requisite dissemination requirements.
- Has a strategic program for preservation planning and action.
- Has technical infrastructure adequate to continuing maintenance and security of its digital objects.
