Weighting

Describes the weighting used in the process. In addition to a description of the weighting process it may be designated as a specific type of weighting. If the data uses a standard weight (each record has an equal weight) it may be expressed here with StandardWeight.

Properties

Description

TypeOfWeighting

CodeValueType

0..1

Allows brief identification of Weighting Process used with the option of using a controlled vocabulary.

Description

StructuredStringType

0..1

Full description of the weighting process. Supports multiple language versions of the same content as well as optional formatting of the content.

WeightingMethodologyReference

WeightingMethodology

0..n

A reference to the methodology used for the weighting process.

AnalysisUnit

CodeValueType

0..1

The entity to which the weights apply, 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.

UsageGuide

UsageGuideType

0..1

A guide to the appropriate usage of the weights generated by the processing event.

StandardWeight

StandardWeightType

0..n

A standard weighting factor used by all or a group of variables within the data set.

BasedOnSampleReference

Sample

0..n

The sample that was the basis for the weighting. TypeOfObject should be Sample.

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.

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.
