The Digital Preservation Problem:1. Rapid technological change drives constant system upgrades,migrations and retirement of legacy technologies.2. Incompatible, obsolete, obscure or proprietary systems and fileformats.3. Loss or damage to bitstreams due the fragility of digital storagemedia, system error, or human error.
The Digital Preservation Problem:4. The overwhelming volume of digital information objects createddaily, each with many possible copies and versions.5. The lack or loss of adequate metadata describing digitalinformation objects.6. Accidental or malicious content alteration.
The Digital Preservation Problem:7. Doubts about the reliability and integrity of electronic recordsand the inability to vouch for their authenticity.8. The complexity of digital information objects which requirespreservation of their content, structure, context, presentation,behaviour as intellectual entities as well as bitstreams.9. The lack of formally recognized organizational responsibility,resources and enterprise architecture components that facilitatedigital curation, preservation and long-term access.

What is Archivematica?● allows users to process digital objects from ingestto access in conformance with the ISO-OAISfunctional model● creates high-quality, standards-compliant ArchivalInformation Packages (AIP)● provides an architecture for implementingpreservation strategies● provides a framework for evaluating andimplementing format policies

Preservation planning● A two-pronged approach:– Normalization on ingest– Preservation of the original file to support futurestrategies such as migration and emulation● Normalization relies on format policies based on ananalysis of the significant characteristics of fileformats● A format policy indicates the actions, tools and settings toapply to a file of a particular file format (e.g. normalization topreservation and/or access format)
Archivematica format policies● Criteria for selecting default formats:● Non-proprietary● Freely available specifications● Widely used/endorsed by major repositories● No compression/lossless compression● Tools available to write and render the format● Format policies will change as communitystandards, practices and tools evolve.
