# GeographicUnitTypeClassification - Properties and Relationships

## Properties

Name | Type | Cardinality
--- | --- | ---
contains | GeographicUnitTypeIndicator | 0..n
displayLabel | LabelForDisplay | 0..n
isCurrent | Boolean | 0..1
isFloating | Boolean | 0..1
releaseDate | Date | 0..1
usage | InternationalStructuredString | 0..1
validDates | DateRange | 0..1

### contains

Define the code and Unit Type that is a member of the Geographic Unit Type Classification. They may be unordered or ordered and assigned to a specific level.

### displayLabel

A structured display label providing a fully human readable display for the identification of the object. Supports the use of multiple languages and structured text.

### isCurrent

Indicates if the Statistical Classification is currently valid.

### isFloating

Indicates if the Classification is a floating classification. In a floating statistical classification, a validity period should be defined for all Classification Items which will allow the display of the item structure and content at different points of time. (Source: GSIM StatisticalClassification/Floating)

### releaseDate

Date the Classification was released

### usage

Explanation of the ways in which some decision or object is employed. Supports the use of multiple languages and structured text.

### validDates

The date the statistical classification enters production use and the date on which the Classification was superseded by a successor version or otherwise ceased to be valid. (Source: GSIM Statistical Classification)

### isMaintainedBy

Organization, agency, or group within an agency responsible for the maintenance and upkeep of the classification.

### isReplacedBy

Geographic Unit Type Structure that supersedes the actual Classification (for those Classifications that are versions or updates),

### isStructuredBy

A relation structure used to describe complex relationships between the members

### realizes

Collection class realized by this class

### references

May reference an existing concept system generally of Geographic Unit Types

### replaces

Geographic Unit Type Structure superseded by the actual Classification (for those Classifications that are versions or updates).

### variantOf

Geographic Unit Type Structure on which the current variant is based, and any subsequent versions of that Classification to which it is also applicable.
