DCMI Date WG workplan 2003/2004:

1. 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)
2. Consider potential additional refinements for DC Date:
   • Date captured [DC-Lib]
3. Consider potential additional schemes for DC Date and/or DC Coverage:
   • ISO 8601 [DC-Lib]
   • Any additional schemes that arise from work item one
