• Variable description

Properties

Name	Type		Description
VariableName	langString	0..n	A name for the Variable.
Label	langString	0..n	A display label for the Variable.
Description	langString	0..n	A description of the content and purpose of the Variable.
OutParameter	ParameterType	0..1	Assigns a parameter that contains output from the Variable so that it can be bound to an InParameter of an instruction or act as the SourceParameter of another Variable.
SourceParameterReference	ParameterType	0..1	Reference to an OutParameter that serves as the source for the content of this variable.
SourceVariableReference	Variable	0..n	Reference to variable(s) used as a basis for recoding, derivation, or other means of calculating the data for this variable. This reference is intended to provide basic information on the source variable structure including value representation, measurement unit, etc. Note that if a variable is used by reference within multiple VariableSchemes you can identify its role within a specific VariableScheme by including that VariableScheme in the sourceContext attribute of the reference. Use ProcessingInstructionReference to provide additional information on the transformation of the source variable(s) into the data for this variable. If additional processing detail is required use the InParameter, OutParameter, and ParameterLinkage options in the GenerationInstruction and ProcessingInstructionReference.
RepresentedVariableReference	RepresentedVariable	0..1	Reference to the RepresentedVariable that describes the core of this variable (the RepresentedVariable that the variable is the implementation of). The RepresentedVariable contains the broad reusable specification of the Variable, i.e., concept, universe, and value representation. These may be constrained by specifications within the Variable description. TypeOfObject should be set to RepresentedVariable.
ConceptualVariableReference	ConceptualVariable	0..1	Reference to the ConceptualVariable that describes the core of this variable. The ConceptualVariable provides linked Concept and Universe specifications. These may be constrained by specifications within the Variable description. TypeOfObject should be set to ConceptualVariable.
WeightingProcessReference	Weighting	0..1	When isWeight is set to true provide a reference to the Weighting process description used to generate this value. TypeOfObject will be Weighting
UniverseReference	Universe	0..n	Reference to the universe statement containing a description of the persons or other elements that this variable refers to, and to which any analytic results refer. If more than one universe is referenced the universe of the variable is the intersect of the referenced universes.
PopulationReference	Population	0..n	Reference to the population statement describing the persons or other elements that this variable and its analytic results refer to. If more than one population is referenced, the population of the variable is the intersection of the referenced populations.
ConceptReference	Concept	0..n	Reference to the concepts measured by this variable.
QuestionReference	Question	0..n	Reference to question(s) used to collect data for this variable. This references the wording and response domain of the question, not the question flow (if the same question was asked in reference to multiple objects (i.e., Age of each child). Use SourceParameterReference and/or VariableRepresentation/ProcessingInstructionReference to differentiate sources associated with flow patterns or data processing instructions. Constraints: assignable subtypes allowed.
MeasurementItemReference	MeasurementItem	0..n	Reference to measurement(s) used to collect data for this variable.
EmbargoReference	EmbargoType	0..1	Reference to any embargoes placed on the contents of this variable. Embargoes may limit access to the data and/or metadata to specific groups and/or for specified periods of time.
SourceUnit	CodeValueType	0..1	The normal source of the information contained in the variable. In the case of a survey this may be a respondent, proxy, interviewer, or other source. In the case of administrative data the position of a field on a form e.g., “top of page”, “item 3”, “generated by data processor”, etc. Supports the use of an external controlled vocabulary.
AnalysisUnit	CodeValueType	0..1	The entity to which the data refer, for example, individuals, families or households, groups, institutions/organizations, administrative units, etc. Supports the use of an external controlled vocabulary. The DDI Alliance has provided a controlled vocabulary (AnalysisUnit) to support this element at http://www.ddialliance.org/controlled-vocabularies.
UnitTypeReference	UnitType	0..1	Reference to the unit type containing a description of the unit type that this Variable refers to, and to which any analytic results refer. TypeOfObject should be set to UnitType.
VariableRepresentation	VariableRepresentationType	0..1	Describes the representation of the variable in the data set, including allowed content, data typing, and computation information.
IsTemporal	boolean	0..1	Set to “true” if the variable relays time-related information (date, time, season, relative time, etc.).
IsGeographic	boolean	0..1	Set to “true” if the variable relays geographic information, i.e., geographic code, area name, relative location, etc.
IsWeight	boolean	0..1	Set to “true” if the variable is used a weight when analyzing data within the data set. If set to true provide a reference to the Applied Usage of the appropriate Processing Event Weight using WeightingAppliedUsage.

Properties Inherited from Versionable

Name	Type		Description
URN	string	1..1	Constraints: pattern=[Uu][Rr][Nn]:[Dd][Dd][Ii]:[a-zA-Z0-9-]{1,63}(.[a-zA-Z0-9-]{1,63})*:[A-Za-z0-9*@$-_]+(.[A-Za-z0-9*@$-_]+)?:[0-9]+(.[0-9]+)*.
Agency	string	1..1	Constraints: minLength=1; maxLength=253; pattern=[a-zA-Z0-9-]{1,63}(.[a-zA-Z0-9-]{1,63})*.
ID	string	1..1	Constraints: pattern=[A-Za-z0-9*@$-_]+(.[A-Za-z0-9*@$-_]+)?.
Version	string	1..1	Constraints: pattern=[0-9]+(.[0-9]+)*.
UserID	UserIDType	0..n	Allows for the specification of identifiers other than the specified DDI identification of the object. This may be a legacy ID from DDI-C, a system specific ID such as for a database or registry, or a non-DDI unique identifier. As the identifier is specific to a system the system must be identified with the UserID structure.
UserAttributePair	StandardKeyValuePairType	0..n	A system specific user defined property of the object expressed as a key/value pair. As this is specific to an individual system the use of controlled vocabularies for the key is strongly recommended.
VersionResponsibility	string	0..1	Person or organization within the MaintenanceAgency responsible for the version change. If it is important to retain the affiliation between and individual responsible for the version and his/her agency, it may be included in this notation. This is primarily intended for internal use.
VersionResponsibilityReference	Agent	0..1	Reference person or organization within the MaintenanceAgency responsible for the version change, as described in an OrganizationScheme. If it is important to retain the affiliation between and individual responsible for the version and his/her agency, a Relation should be created between the individual referenced here and his/her organization. This is primarily intended for internal use. Constraints: assignable subtypes allowed.
VersionRationale	VersionRationaleType	0..1	Textual description of the rationale/purpose for the version change and a coded value to provide an internal processing flag within and organization or system. Note that versioning can only take place on objects owned by the specified DDI Agency. If you are creating a local instance of an object from another agency for current or future modification use BasedOnObject. If the changes being made result in what you determine to be new object rather than a version of a previous object, i.e. the change is too extensive to consider it a version of the existing object, create a new object and use BasedOnObject to provide a link to the object or objects that were a basis for the new object.
BasedOnObject	BasedOnObjectType	0..1	Use when creating an object that is based on an existing object or objects that are managed by a different agency or when the new object is NOT simply a version change but you wish to maintain a reference to the object that served as a basis for the new object. BasedOnObject may contain references to any number of objects which serve as a basis for this object, a BasedOnRationalDescription of how the content of the referenced object was incorporated or altered, and a BasedOnRationalCode to allow for specific typing of the BasedOnReference according to an external controlled vocabulary.
RelatedOtherMaterialReference	OtherMaterial	0..n	The inclusion of an existing OtherMaterial by reference. Use for any type of OtherMaterial not specifically addressed by an inline description for such as ExternalAid in QuestionItem.
VersionDate	cogsDate	0..1	Date of version using the union set BaseDateType. Duration should not be used in this field, even though allowed by the ISO format enforced by the parser.
IsPublished	boolean	0..1	Indicates that the maintainable will not be changed without versioning, and is a stable target for referencing.
