ReferenceDate

The date covered by the annotated object. In addition to specifying a type of date (e.g. collection period, census year, etc.) the date or time span may be associated with a particular subject or keyword. This allows for the expression of a referent date associated with specific subjects or keywords. For example, a set of date items on income and labor force status may have a referent date for the year prior to the collection date.
