NominalDomainType

A response domain capturing a nominal (check off) response for a question grid response. Includes standard response domain elements; OutParameter, designation of response cardinality, and a declaration of an offset date for the data content.

Properties

Name	Type		Description
Label	LabelType	0..n	A display label for the domain. Supports multiple language versions of the same content as well as optional formatting of the content. Repeat for labels with different content, for example, labels with differing length limitations.
Description	StructuredStringType	0..1	A description of the content and purpose of the domain. Supports multiple language versions of the same content as well as optional formatting of the content.
OutParameter	ParameterType	0..1	Allows for the response to be bound to one of the QuestionItem’s OutParameters, so the collected information can be used elsewhere, for example as inputs to subsequent questions in an Instrument or to a GenerationInstruction. If multiple responses are possible, this would represent and ordered array of the responses.
ResponseCardinality	ResponseCardinalityType	0..1	Allows the designation of the minimum and maximum number of responses allowed for this response domain.
ContentDateOffset	ContentDateOffsetType	0..1	Identifies the difference between the date applied to the data as a whole and this specific item such as previous year’s income or residence 5 years ago.

Name	Type		Description
RecommendedDataType	CodeValueType	0..1	This field provides the recommended treatment of the data within an application. The value should come from a controlled vocabulary - recommended values include the set found in W3C XML Schema Part 2, but excluding string sub-types, QNAME, and NOTATION. The DDI Alliance has provided a controlled vocabulary (DataType) to support this element at http://www.ddialliance.org/controlled-vocabularies.
GenericOutputFormat	CodeValueType	0..1	This field provides a recommended generic treatment of the data for display by an application. The value should come from a controlled vocabulary.
MeasurementUnit	CodeValueType	0..1	Records the measurement unit, for example, ‘km’, ‘miles’, etc. Supports the use of a controlled vocabulary.
MissingValue	string	0..1	List the values used to represent missing data. Use of MissingValuesReference is preferred. If this content does not match the values provided in the MissingValuesReference, the content of the MissingValuesReference overrides the content of this attribute.
BlankIsMissingValue	boolean	0..1	When value is true a blank or empty variable content should be treated as a missing value. Use of MissingValuesReference is preferred.
ClassificationLevelCode	CodeValueType	0..1	Indicates the type of relationship, nominal, ordinal, interval, ratio, or continuous. Use where appropriate for the representation type. Valid values include: Nominal, Ordinal, Interval, Ratio, Continuous
