      • Conclusion
    • Importance of Digital Preservation
      • 1975 – Two Viking space probes sent to Mars by USA.
      • Data generated by unrepeatable mission cost $1 billion.
      • Recorded data on magnetic tapes was corrupted / unidentifiable after 2 decades despite being kept in climate controlled environment.
      • Scientists could not access data, unable to decode the formats used.
    • Importance of Digital Preservation
      • Original format developers not alive.
      • Finally old printouts tracked and retyped.
      • NASA therefore is biggest supporters of Digital Projects.
      • This illustrates wide gap in information generation and its management.
    • Need for Digital Preservation
      • Huge scientific data 259 MB/person/yr. is being generated (having economic value).
      • 90% is stored digitally.
      • This provides huge opportunities for long term digital preservation.
      • Initiatives for long term preservation needed with common goal, centrally funded activities with partnership and collaboration.
    • Stakeholders of Preservation
      • Libraries
      • Archives
      • Museums
      • Scientific Institution
    • Role of Libraries / Archives in Preservation activities
      • Maintaining digital material for long term
      • Conservation : Treatment for stability
      • Restoration (Bring back document to its original state)
    • Strategies for Preservation
      • Technical Preservation (hardware / software of object)
      • Technology Emulation (Mimic original environment using latest software)
      • Data Migration (Transfer digital materials from one format to current one).
    • Two Main Digital Preservation Approaches
      • Preservation through digitization (for greater security / saving space / producing multiple copies).
      • Born digital – (Convert information form from Analog to Digital).
      • Digitization costly but necessary for human progress.
      • Appropriate action by individuals / organization needed.
    • Technical Approaches to Archiving
      • Open Archival Information System (OAIS)
      • Published by consultative committee for space data system (CCSDS) 2002
      • ISO 14721 : 2003 standard
      • An archive consists of organization of people and systems with responsibility to preserve information and make it available to users.
    • Technical Approaches to Archiving
      • Three key players of OAIS model in archiving are :
      OAIS MODEL Creator Archive Operator Designated user community
    • Creator : Some of players are
      • Authors
      • Copyright owners
      • Professional societies
      • Publishers
      • Distributors
      With so many players rights of ownership and responsibility to provide content to archive needs to be addressed.
    • Archive Operator
      • Collection policy needs attention (Based on topic / subject / user community addressed)
      • Boundary of archiving activity needs to be defined.
      E.g. National library of New Zealand collects electronic material using PUSH / PULL Business Process & online publication with purview copyright and community licensing agreements.
    • Users
      • Archiving should consider needs of specified user community.
      • Changing needs of user community
      • Change of users with time
      • Issue of access to archive, domain of material (Private vs. Public) needs to be addressed specifically.
      • Responsive and automated access control system required to facilitate use and save archive to problems arising out of user and third partly interaction.
    • Tools for quality of Digital Objects
      • Preservation Web Services Architecture for New Media and Interactive Collections (PANIC), Australia
      • Preserving Access to Digital Information (PADI), the National Library of Australia
      • PRONOM Project, National Archives, UK
      • Preservation and Long-Term Access via Networked Services (PLANETS), European Union
    • Web Archiving
      • Started in 1996 to tap wealth of information on web before they vanish.
      • Special software products i.e. web crawlers / spiders employed.
      • They have limitations like non-coverage of some hidden content, unable to interpret certain codes for links and long time to retrieve archived web pages.
    • Strategies for Web Archiving
      • Making a local copy of the files of a web site and navigating through this copy
      • Running a web server to make accessible the contents to the user
      • Reorganizing documents in a non-web manner
      Examples: - Minerva, U.S. Library of Congress - Way Back Machine , Internet Archive, USA
    • Metadata and Digital Preservation
      • Creation and maintenance of metadata required for long term preservation of digital information.
      • Within Archive
      • Metadata (maintained / migrated format to format & standard to standard independent of objects it describes).
      • Refers each digital object and provides
      • Descriptive Structural Administrative Rights Management Other information
    • Metadata and Digital Preservation
      • Metadata preservation is popular area of research in last decade.
      • Research Library Group (RLG) at NLA has developed model to identify entities that supports its PANDORA (Preserving & Accessing Networked Documentary Resources of Australia) to support archive concept.
    • OAIS Model and Metadata Source: Day, M.,
    • OAIS and Metadata Implementation
      • NEDLIB Project National Library of Netherlands
      • DSEP (Deposit System for Electronic Publication)
      • CURL (Consortium of Univ. Res. Libraries of Cambridge, Leeds & Oxford).
      • PREMIS (Preservation Metadata : Implementation Strategies Working Group) sponsored by OCLC / RLG.
      • IIPC (International Internet Preservation Consortium) developed archival metadata scheme)
      • PID (Persistent identifier) assigns unique name to a digital object that points to bibliographic record.
      • URN (Uniform Resource Name) refers to identifiers.
      OAIS and Metadata Implementation
    • IPR & Copyright
      • Different countries are addressing issues are IPR and copyright with respect to digital preservation.
      • National Libraries responsible for archiving national domain.
      • Examples :
        • Library of Congress : best practices for digital preservation
        • Koninklyke Bibliotheek (KB), the National Library of The Netherlands : individual, collective and the ‘opt-out’ approach to archiving scholarly journals
