Date when feature happened.

Formatting

Dates use the ISO 8601 system, which is based on the Gregorian calendar.

Examples:

  • 2010 ; where the year is known, but no more
  • 0897 (for 897 AD)
  • 1848-07 ; where the year and month are known
  • 2010-03-31 ; for where the full date is known, using the format yyyy-mm-dd

Caution: ISO8601 uses the format yyyy-mm-dd, not the common North American model of mm-dd-yyyy
