Two entirely different things

• Digitization for preservation
• Reduce handling of non-digital originals
• Increase access
• Alternative to microfilming or analog
  reformatting
• Digital preservation
• How to ensure long-term usability of digital
  objects
• Protect from loss of data, media and software
  obsolescence
• Maintain authenticity and understandability

Towards trusted digital repositories

• Preserving Digital Information (RLG/CLIR, 1996)
• Trusted Digital Repositories (OCLC/RLG, 2002)
• Digital Repository Certification Task Force
  (RLG/NARA, ongoing)
• Working Group on Trusted Repositories
  Certification (nestor, ongoing)
• CRL Certification of Digital Archives

Preserving Digital Information

• A critical component of the digital archiving
  infrastructure is the existence of a sufficient
  number of trusted organizations capable of
  storing, migrating, and providing access to
  digital collections
• A process for certification of digital archives
  is needed to create an overall climate of trust
  about the prospects of preserving digital
  information.

Trusted Digital Repositories Attributes and
Responsibilities

• Defined Trusted Digital Repository
• Listed Attributes of a TDR
• Listed Responsibilities of a TDR
• Discussed and Called for Certification of TDR

A trusted digital repository

• is one whose mission is to provide reliable,
  long-term access to managed digital resources to
  its designated community, now and in the future.
• May be locally run or third-party
• Must accept responsibility for the long-term
  maintenance of digital resources on behalf of its
  depositors and for the benefit of current and
  future users
• Meets organizational, curatorial and operational

Stewardship is easy inexpensive to claim it
is expensive and difficult to honor, and perhaps
it will prove to be all to easy to later
abdicate. Clifford Lynch
11
Digital Repository Certification Task Force charge

• Identify a list of certifiable elements
  (attributes, processes, functions, activities) of
  a digital repository or types of repositories
• Create a standard certification process or
  framework that can be implemented across domains
  or types of digital repositories
• Define the conditions for revocation of
  certification and suggest appropriate action
  plans for endangered digital information

12
Emerging Certification Framework

• Cross-domain, international, repository neutral
• Key responsibilities and certification metrics
• Dual-purpose toolkit
• Self-evaluation
• Independently administered audit
• Draft for pubic comment due July 2005
• www.rlg.org/en/page.php?Page_ID580

nestor Working Group

• Network of Expertise in Long-Term Storage of
  Digital Resources (nestor)
• Repository certification effort based on TDR
• Started December 2004
• German academic libraries only
• Begin with low bar for certification and raise
  over time

14
CRL Certification of Digital Archives

• Mellon-funded, began May 1, 2005
• Focuses on resources not necessarily owned by
  community (e.g. ejournals, news)
• Will develop processes and activities required to
  audit and certify digital archives
• Target archives
• Koninklijke Bibliotheek
• Ithakas Portico
• Medical journals

15
CRL Project Phases

• Design audit process and documentation of metrics
  and terminology to be used
• Model audit process through test audits of three
  repositories
• Develop the profile and business model for a
  certifying agency
