Lifecycle Approach to Digital Curation and
Preservation

• A Lifecycle approach is necessary because
• Digital materials are fragile and susceptible to
  change from technological advances from creation
  onwards
• Activities (or lack of) at each lifecycle stage
  influence ability to manage and preserve
  materials in subsequent stages
• Reliable re-use of digital materials is only
  possible if materials are curated in such a way
  that their authenticity and integrity are
  retained.
• Facilitates continuity of service
• Supports verification of provenance
• Helps maximise initial investment made in
  creating or gathering data
• Requires significant input and buy-in from the
  range of stakeholders creators, curators, IT
  staff, management.
• From Pennock, Maureen, Digital Curation A
  Life-Cycle Approach to Managing and Preserving
  Usable Digital Information, (2007)

Project Aim - Internal

• Planning tool
• Framework for DCC output
• tools, services, research, eScience liaison
• Identify gaps in DCC materials
• Move to lifecycle approach to resource creation,
  management and presentation

Project Aim- External

• Enable others to
• Plan curation and preservation activities
• Map granular functionality
• Define roles and responsibilities
• Build framework of standards and technologies
• Identify additional steps required
• Identify steps not required
• Ensure adequate documentation

DCC Curation Lifecycle Model Aims

• Curation specific model
• Generic graphical high level overview of
  lifecycle stages
• Organisational planning tool
• Extensible for greater granularity
• Adaptable for different domains
• Complement not restate - a number of lifecycle
  applicable standards
• OAIS
• ISO 15489
• MoReq2
• Indicative not exhaustive

Scope notes

• Added in response to DCC team comment
• Generic language
• Cross domain understandability
• No specific standard quoted

Records Continuum Model - 1996

• Archives and records management discipline
• Identification, control and access of electronic
  records

E-Science Curation Report - 2003

• E-science discipline - databases
• Takes integrated look at higher education data
  curation problems
• Poor granularity on curation activities

11
InterPARES- Chain of Preservation - 2005

• Records management / archives discipline
• Very detailed workflow for preservation
  activities
• Identifies key relationships and activities
• An audit tool for lifecycle management or service
  development

12
SherpaDP - 2006

• Institutional Repository focus
• Specific to ePrints
• Policies on submission format and permission for
  preservation processes
• Creator / preserver relationships

  of digital objects
• Deals with costing activities
• Enables cost of preservation to be calculated

Paradigm Project - 2007

• Archives and records management discipline
• OAIS implementation
• Project specific

Reference Models / Frameworks

• ISO 147212003 - Open Archival Information
  Systems Reference Model (OAIS)
• ISO 206522006 - Producer-archive interface --
  Methodology abstract standard (PAIMAS)
• ISO 154892001 Information and documentation --
  Records management

17
OAIS -1

• Consultative Committee for Space Data Systems
• Good on ingest and post-ingest activities
• Weak on pre-ingest activities
• Basis for other initiatives
• PREMIS data dictionary
• Trusted Digital Repository Audit and
  Certification

18
OAIS - 2

• Mandatory responsibilities
• Negotiate for and accept appropriate information
  its producers
• Obtain sufficient control of information to
  ensure Long-Term Preservation.
• Determine the Designated Community
• Ensure information preserved is independently
  understandable to the Designated Community
  without expert assistance
• Follow documented policies and procedures which
  ensure that the information is preserved against
  all reasonable contingencies, and which enable
  the information to be disseminated as
  authenticated copies of the original or traceable
  as the original.
• Make the preserved information available to the
  Designated Community.
