A Distinction
  • Metadata Harmonization
  • the ability to use serveral different metadata
    standards in a single software system.
  • Metadata Normalization
  • mapping serveral different metadata standards to
    a single schema or structure for use in a single
    software system.

  • Standard URIs for concepts and agents
  • Possibly for FRBR Entities?
