1
Interoperability, OAI, and Shareable Metadata
  • Sarah Shreeves
  • University of Illinois at Urbana-Champaign
2
The Four C’s (and lots of S’s)
of Shareable Metadata
  • Consistency
  • Coherence
  • Context
  • Conformance


  • Metadata standards (and not just DC)
  • Vocabulary and encoding standards
  • Descriptive content standards (AACR2, CCO, DACS)
  • Technical standards (XML, Character encoding, etc)
3
But also…
  •   Communication


    • AND


    • Documentation
4
OAI Use of Dublin Core

  • DC is the OAI protocol’s lowest common denominator


  • BUT


  • Data providers can and SHOULD be providing records in additional metadata formats
