Title: National Library of New Zealand

National Library of New Zealand
  • Dave Thompson
  • Resource Development Analyst 
  • Digital Initiatives Unit

  • NLNZ is working with the Handle System as a way
    of developing and testing the use of persistent
    identifiers - PIDs - to permanently identify
    digital materials.

Two fold approach
  1. Structure and design/naming schema of handles,
    handle workflows/administration, application and
    use of Handles and identifiers in NLNZ
  2. Technical environment hardware/software
    environment, networks, capacity/load issues,
    resolution issues

  • This proposal for the allocation of PIDs is based
    on the following principles
  • The primary purpose of the PID is to provide a
    unique and permanent name, and resolution is an
    added value.
  • The PID object relationship is a permanent one.
    If the content of the digital object changes a
    new PID is allocated.

  • The Handle prefix has been split to represent
    archival and non-archival collections. NLNZ
    assigns PIDs using two issuing authorities.
    Represented as
  • Resources selected for the digital archive,
    represented by a sequence of 1727.10/nnnnnnnn,
  • Non archival resources, represented by a sequence
    of 1727.11/nnnnnnnn

This split between archival items selected for
other purposes reflects different degrees of
commitment the NLNZ has to preserving the digital
  • NLNZ has not yet fully addressed all of the
    technical issues required to implement the Handle
  • Key work is required on
  • Robustness of the Handle model when scaled up to
    work at a national level, the ability to
    integrate the Java tool into existing systems and
    workflow structures
  • Multiple resolution and how we apply what
    functionality is available
  • Potential performance / capacity / volume issues
    when many users channel requests through our
    single Handle server
  • Size of hardware environment. Need for /
    advantage of multiple servers
  • Network. Capacity / routing issues using
    different Handle resolution formats (HTTP, HDL,

Further questions
  • DOI uses the Handle system. What is the
    relationship between the basic Handle system and
    DOI? Is DOI a wrapper around the Handle? Who
    developed DOI and who owns it?
  • Compatibility issues, can we adapt Handle system?
    If so where is the international infrastructure?
  • What other persistent identifiers are out there
    or on the horizon?

  • Discover is a resource of the National Library of
    New Zealand and is an online treasure trove of
    New Zealand art and music that supports the
    Visual Arts and Music disciplines of the Arts/Nga
    Toi curriculum.
