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 file
formats.
3. Loss or damage to bitstreams due the fragility of digital storage
media, system error, or human error.

The Digital Preservation Problem:
4. The overwhelming volume of digital information objects created
daily, each with many possible copies and versions.
5. The lack or loss of adequate metadata describing digital
information objects.
6. Accidental or malicious content alteration.
![Page 7: 2013 05-15 Intro to Archivematica - UBC SLAIS Digital Records Forensics Class](https://reader033.fdocuments.us/reader033/viewer/2022051817/547baabd5806b5c73f8b4653/html5/thumbnails/7.jpg)
The Digital Preservation Problem:
7. Doubts about the reliability and integrity of electronic records
and the inability to vouch for their authenticity.
8. The complexity of digital information objects which requires
preservation 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 facilitate
digital curation, preservation and long-term access.

Preservation planning
● A two-pronged approach:– Normalization on ingest
– Preservation of the original file to support future strategies such as migration and emulation
● Normalization relies on format policies based on an analysis of the significant characteristics of file formats
● A format policy indicates the actions, tools and settings to apply to a file of a particular file format (e.g. normalization to preservation 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 community standards, practices and tools evolve.
