Means of describing DateTime so that they can be reused by multiple variables or questions/question constructs. Regardless of the format of the data the content may be treated as a date and or time and converted to ISO standard structure if sufficient information is supplied. In addition to the name, label, and description of the representation, the structure provides the DateField Format, a DateTypeCode and a regular expression for further defining allowed content. The DDI Alliance has provided a controlled vocabulary (DateType) to support this element at http://www.ddialliance.org/controlled-vocabularies.
