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 Assessing the risks for loss of content posed by technology variables such as commonly used proprietary file formats and software applications. Evaluating the digital content objects to determine what type and degree of format conversion or other preservation actions should be applied. Determining the appropriate metadata needed for each object type and how it is associated with the objects. 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 Preservation "the information the digital repository uses to support digital preservation process"

Digital Preservation - Metadata PREMIS Data Dictionary Provenance Who has had custody/ownership of the digital object? Authenticity Is the digital object what it purports to be? Preservation Activity What has been done to preserve the digital object? Data Dictionary defines a core set of semantic units that repositories can use to perform

Digital Preservation - Metadata PREMIS Data Dictionary (cont.) Technical Environment What is needed to render and use the digital object? Rights Management What intellectual property rights must be observed? -- PREMIS Information Sheet --- http://www.loc.gov/standards/premis/information-sheet.pdf -- Understanding PREMIS -- http://www.loc.gov/standards/premis/understanding-premis.pdf -- PREMIS Data Dictionary -- http://www.loc.gov/standards/premis/v2/premis-dd-2-1.pdf
