3. Two Foundation Documents Trusted Digital Repositories: Attributes and Responsibilities (RLG/OCLC) www.rlg.org/longterm/repositories.pdf OAIS Reference Model (CCSDS) ssdoo.gsfc.nasa.gov/nost/wwwclassic/documents/pdf/CCSDS-650.0-B-1.pdf

4. Attributes of a Trusted Repository OAIS Compliance • Administrative Responsibility • Organizational Viability • Financial Sustainability • Technological and Procedural Suitability • System Security • Procedural Accountability

6. OAIS Reference Model

7. OAIS Functional Groups

8. Foundation Documents • TDR on its own lacks an implementation model • OAIS on its own lacks organizational context • Together, they leverage community-based efforts and enable collaborative initiatives

9. Merged Model

10. Three Legs Organizational Infrastructure Technological Infrastructure Resources Framework $$$$

12. Organizational Infrastructure • Best expressed by TDR • Best reflected in: • acknowledgement • policy development • implementation • preservation planning • institutional commitment

13. TechnologicalInfrastructure • Best expressed by OAIS • Combination of: • hardware and software • formats and storage • network and security • functions and workflow • procedures, protocols, documentation • technical and archival skills

14. $$$$ ResourcesFramework • No community-based articulation comparable to TDR or OAIS • Includes: • staff • technology • training • other

15. Five Organizational Stages • Acknowledge:understanding that digital preservation is a local concern • Act:initiating digital preservation projects • Consolidate:segueing from projects to programs • Institutionalize:incorporating the larger environment and rationalizing programs • Externalize:embracing inter-institutional collaboration and dependency

24. Stage 5: Externalize Embracing inter-institutional collaboration and dependencies
