>2. Finalize our working agenda.  I've made minor revisions based on
discussion on the list, and incorporated the substance of former charter
point 3
(3. In consultation with other interested DCMI WG's:
- identify categories of commonly-recorded dates which cannot be
satisfactorily represented using ISO 8601 or other well-established
international standards governing the representation of dates
- investigate options to provide for the interoperable representation of
these types of dates.)


>2003-2004 work plan (proposed):

In consultation with other interested DCMI WG's:

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:
a. B.C.E. dates [DC-Lib; DC CLD WG]
b. Questionable dates [DC-Lib]
c. Approximate dates [DC-Lib]
d. Open-ended date ranges [DC CLD WG]
e. Non-Gregorian dates
f.  Large dates (e.g., geologic periods, astronomical time)

2. Consider potential additional refinements for DC Date:
a. Date captured [DC-Lib]

3. Consider potential additional schemes for DC Date and/or DC Coverage:
a. ISO 8601 [DC-Lib]
b. Any additional schemes that arise from work item one

4. Other issues/items:
a. Is W3CDTF is an encoding scheme for single dates rather than a date
range? (We think so, but perhaps confirm?)
b. What does DC Library WG report of "ISO 8601 (without hyphens) approved
June 2003 (e.g. 20030928=Sept. 28, 2003)" mean?
c. Generally clarify what the UB has already approved with respect to
date/time notation (including specifically confirming that W3CDTF is a valid
encoding scheme for the date element refinements)
d. Generally consider the dimension of "open" vs. restricted-access
standards in our discussions and recommendations
e. Generally consider how best to address conveying which version of a
standard is being used as the date/time scheme
