Dublin Core

Besides initiating processes for the review and approval of new Dublin Core elements and qualifiers, the DCMI Usage Board has revamped the way Dublin Core Metadata Initiative documents its work. The documents currently include:
  • Up-to-the-minute listings of all current Elements, Element Refinements, Encoding Schemes, and DCMI Type Vocabulary terms. These will supersede Web documents currently in use as authoritative sources of up-to-date information on DCMI metadata terms.
  • For the historically- or archivally-minded, a complete listing of all Elements, Element Refinements, and Encoding Schemes -- including past versions of terms that have been corrected or revised. Each term has a cross-reference to a related Decision, and each such Decision points to supporting documentation in the archive. This master file is used as the source for periodically generating the updated listings.
  • DCMI Usage Board Decisions, each of which is numbered for unambiguous identification.
  • DCMI Usage Board Review of Application Profiles -- principles and criteria by which the Board will review profiles which use or extend Dublin Core in various ways.

At its latest meeting, held on 12-13 May 2002 in Bath with financial support from JISC, the Usage Board revised and simplified its model for conferring status on terms, making it easier for working groups to put new terms of proven usefulness into the DCMI-maintained namespaces.

The Usage Board now distinguishes the following:

  • "Recommended" Elements, Element Refinements, and DCMI Type Vocabulary terms useful for resource discovery across domains.
  • "Conforming" Elements and Element Refinements -- terms for which an implementation community has a demonstrated need and which conform to the grammar of Elements and Element Refinements, though without necessarily meeting the stricter criteria of usefulness across domains or usefulness for resource discovery.
  • "Registered" Encoding Schemes -- terms which identify parsing rules or controlled vocabularies useful for interpreting particular metadata values. All encoding schemes, new and legacy, have the status of Registered.
