How might different calendaring systems be applied using a similar template structure to that needed for name elements above?
Note: Calendaring systems also have a geographical/governmental/cultural aspect to them that is not necessarily captured by simply naming a calendaring system. A geographical name or other information might be required.
What accommodation needs to be made in genealogical data for time zone information?
Types of Date Information
An oft-overlooked aspect of date/time information is categorizing it by the type of time it represents.
Between (Unspecific time) (bet)
After (aft) (c)
Interpreted (Int) - indicating modification which could include conversion from another calendar, calculation from a relative-time reference, or other uses
Relative (is this expressed in ways other than a text entry?)
Text (e.g., "Christmastime, 1986" which to me could be in early Jan. 1987 or simply "Spring")
These are just examples. Is there a difference in "Timespan" and "Between" for our purposes? Should BetterGEDCOM make a distinction between these two? What other Time Types are there?
Day (dd) Only
Month (mm) Only
Year (yyyy) Only
Month / Year (mmyyyy)
<time1> (24 hour HH:MM)
