What is 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
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.
-- Online Computer Library Center, Inc. (2006). OCLC Digital Archive Preservation Policy and Supporting Documentation, p. 5
Digital Preservation - Content Creation
Content creation includes:• Clear and complete technical
specifications• Production of reliable master files• Sufficient descriptive, administrative and
structural metadata to ensure future access
• Detailed quality control of processes
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
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
Digital Preservation - Content Maintenance (cont.)
• Programs for refreshing, migration and emulation
• Creation and testing of disaster prevention and recovery plans
• Periodic review and updating of policies and procedures

Digital Preservation - Metadata
What is Metadata?• Descriptive• Administrative• Technical
• Preservationo "the information the digital repository uses to support digital
preservation process"
Digital Preservation - MetadataPREMIS Data Dictionary
• 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
object?

• Rights Managemento What intellectual property rights must be
observed?
