Definition Date on which the resource was changed.

This may be used to distinguish among versions of a resource when multiple versions have been made available.

Follow W3C-DTF standard (ISO 8601) of YYYY-MM-DD.

Use only as much of the date as is known.

  • If only the month and year is known, use YYYY-MM.
  • If only the year is known, use YYYY.

Use a question mark to show a date is approximate or a circa date.

Use dashes to indicate uncertainty within a decade or a century.

  • YYY-?
  • YY--?

Do not use "Unknown"--just leave the field blank.

For a range of dates, put a dash in between dates.
