1. The OAIS model SEEDS meeting May 5 th, 2015, Lausanne Bojana Tasic

2. The Open Archival Information System model 2 ISO 14721:2003

3. Elements  Things happen: Functional Entities  People make them happen: Actors  Data is stored: Information packages 3

4. Functional Entities 4

5. Information packages 5

6. 6 += SIP +=Digital object Meta data Information package

7. Information packages 7 Submission Information Package Archival Information Package Dissemination Information Package

8. Actors 8

9.  Producers  Person, agency or a system, that deposit data (data producers, depositors, researchers)  Consumers  People who use the data (readers, researchers, academics, public, user community)  Management  People who work in the archive (data managers, archivists, programmers, database managers, data center managers) 9

10. Ingest  Receive submission  Quality assurance  Transform SIP into AIP  Extraction of descriptive metadata  Transfer of the AIP to Data Management and Archival Storage 10

11. Ingest 11 Log receipt Virus Scan Checksum creation Generate UID Identify file formats Validate file formats Extract technical metadata Any access permission issues?

12. Ingest 12 SIP AIP I am a submitted file with a transfer date and some metadata I have a checksum, virus scan report, file format identification metadata, file format validation metadata, rights metadata, digital object converted in archival format…and a UID

13. Anatomy of an AIP 13 AIP Wrapper UID 9585236 Metadata Digital object

14. Data management  Manage metadata in database  Keep a record of actions  Manage UIDs  Perform queries on databases  Generating reports 14

15. Archival Storage  Store AIP (physical files)  Media migration  Media replacement  Disaster recovery  Security 15

16. Preservation planning  Monitor the environment  Provide recommendations and preservation plans  Policies  Technology watch 16

17. Communication with Producer Develop preservation strategies Develop standards Design IP 17

18. Communication with Consumer Monitor the community What do they want? Monitor technology How can we deliver data? 18

19. Administration  Auditing submissions  Negotiating with Producers  Managing the configuration of the system  Ensure that the system conforms with policies 19

20. Communication with Producer Negotiate with Producer Audit submissions Agree format standards Define access permission Define metadata for SIP 20

21. Communication with Consumer Support service How they can access the data? What file formats do they want? 21

22. Access  Services and functions that support Consumers  Generate and deliver DIP 22

23. Access 23 Add catalogue information (descriptive metadata) Basic technical metadata Ensure file format can be read by Consumer Add rights metadata Change file format?

24. Access 24 AIP DIP I am a digital object stored in the digital archive I have been catalogued with descriptive information, I have a technical profile, I’ve got a license for use, and I am in a common readable format…
