- How to ensure digital material stays accessible?
- IT-technology changes rapidly
- Impact of failure is huge

8. Digital preservation

10. OAIS
ISO 14721: functional model
ISO 16363: guidelines for certification
17-5-2013
An OAIS is an Archive […] that has accepted the
responsibility to preserve information and make it
available for a Designated Community.

11. Key concepts for preservation
- Usability: Keeping the data readable for the designated
community
- Integrity: Keeping data from corruption:
technical properties, fixity checking
- Authenticity: audit-trail of actions within the digital lifecycle
in preservation metadata
17-5-2013

12. Events and provenance
- Provenance metadata is a collection of Events
- Events: defined actions with Agent and Outcome saved
as metadata
- Provenance metadata shows the history of the object
17-5-2013

13. Preservation metadata dictionary
- PREMIS as basis for provenance metadata and rights
- Technical metadata for audio, video and still images

15. OAIS processes: the IP-lifecycle
A Producer provides a
Submission Information Package
in accordance with Submission
Agreements
The Archive stores the
Archival Information Package
The Designated Community requests a
Dissemination Information Package
in accordance with Order Agreements

Digital Object + metadata = Information Package

21. Important findings
17-5-2013
Synchronizing theory with practice

- Workflow policies or technical requirements?

22. Important findings
17-5-2013
Learning, communication and
collaboration
- Everyone should know their role and responsibility
- A common reference framework is important

23. Important findings
17-5-2013
