DCMI Date Community

DCMI Date WG workplan 2004/2005:

  1. Respond to a DCMI Usage Board proposal to change the wording of the Comment for the Dublin Core Date element to explicitly acknowledge ranges.
  2. Consider potential additional schemes for DC Date and/or DC Coverage:
    • ISO 8601 DC-Lib
    • Any additional schemes that arise from other work items
  3. Consider potential additional refinements for DC Date:
  • Date captured [DC-Lib]
  • Investigate options to provide for the interoperable representation of commonly-recorded dates which cannot be satisfactorily represented using ISO 8601 Data elements and interchange formats - Information interchange -Representation of dates and times, including the following categories of dates:
  • B.C.E. dates [DC-Lib; DC CLD WG]
  • Questionable dates [DC-Lib]
  • Approximate dates [DC-Lib]
  • Open-ended date ranges [DC CLD WG]
  • Non-Gregorian dates
  • Large dates (e.g., geologic periods, astronomical time)
  • Soft termini (i.e. the outer bounds for one or more termini is known or can be associated with a known period, but one or both of the exact boundaries of the event referenced are not known)
  • Elapsed time less than date range interval (i.e. the duration is less than the complete interval between two termini, as in an intermittent activity)
