What is Digital Preservation?

Page 14: Digitization & Digital Preservation

Digital Preservation - Goals

"Digital preservation combines policies, strategies and actions to ensure access to reformatted and born digital content regardless of the challenges of media failure and technological change. The goal of digital preservation is the accurate rendering of authenticated content over time."

-- Definitions of Digital Preservation - http://www.ala.org/alcts/resources/preserv/defdigpres0408

Page 15: Digitization & Digital Preservation

Digital Preservation - Preservation Strategies

1. Assessing the risks for loss of content posed by technology variables such as commonly used proprietary file formats and software applications.

2. Evaluating the digital content objects to determine what type and degree of format conversion or other preservation actions should be applied.

3. Determining the appropriate metadata needed for each object type and how it is associated with the objects.

4. Providing access to the content.

specifications• Production of reliable master files• Sufficient descriptive, administrative and

structural metadata to ensure future access

• Detailed quality control of processes

Page 17: Digitization & Digital Preservation

Digital Preservation - Content Integrity

Content integrity includes:• Documentation of all policies, strategies

and procedures• Use of persistent identifiers• Recorded provenance and change history

for all objects• Verification mechanisms• Attention to security requirements• Routine audits

Page 18: Digitization & Digital Preservation

Digital Preservation - Content Maintenance

Content maintenance includes:• A robust computing and networking

infrastructure• Storage and synchronization of files at

multiple sites• Continuous monitoring and management

of files

• Provenanceo Who has had custody/ownership of the digital

object?

• Authenticityo Is the digital object what it purports to be?

• Preservation Activityo What has been done to preserve the digital
