OCLC/RLG Preservation Metadata Framework Working
Group

• OCLC/RLG Preservation Metadata Working Group
• Convened March 2000
• Looked at CEDARS, NLA, NEDLIB, OCLC
• Preservation metadata framework (June 2002)
• Synthesized elements from existing sets
• Based on OAIS information model
• Set of prototype preservation metadata elements

PREMIS

• June 2003 OCLC/RLG sponsored new working group
  PREMIS
• Preservation Metadata Implementation Strategies
• Objectives
• Define core set of preservation metadata
  elements, with supporting data dictionary,
  applicable to broad range of digital preservation
  activities
• Identify and evaluate alternative strategies for
  encoding, storing, managing, and exchanging
  preservation metadata

7
Core Elements

• Mission Define a core set of implementable
  preservation metadata elements.

8
Core Elements

• Mission Define a core set of implementable
  preservation metadata elements.
• Information that supports and documents the
  digital preservation process
• Information that supports the the viability,
  renderability, understandability, identity and
  authenticity of digital objects over time.

9
Core Elements

• Mission Define a core set of implementable
  preservation metadata elements.
• What most working preservation repositories are
  likely to need to know.

10
Core Elements

• Mission Define a core set of implementable
  preservation metadata elements.
• As rigorous as possible
• As much explanation as possible
• Implementation neutral -- This is what you have
  to know
• Values can be automatically supplied and
  processed -- no lengthy textual descriptions
