Attributes

Definition: External object identifier of the spatial object.

Description: An external object identifier is a unique object identifier published by the responsible body, which may be used by external applications to reference the spatial object. The identifier is an identifier of the spatial object, not an identifier of the real-world phenomenon.

Multiplicity: 1

Valuetype: Identifier

Definition: Descriptive unique object identifier applied to spatial objects in a defined information theme.

Description: Some statistical units may be assigned multiple thematic identifiers.EXAMPLE: NUTS codes are thematic identifiers.

Multiplicity: 0...*

Valuetype: ThematicIdentifier

Definition: The code of the country the object belongs to.

Multiplicity: 1

Valuetype: CountryCode

Definition: Possible geographical names of the object.

Multiplicity: 0...*

Valuetype: GeographicalName

Definition: Date and time at which this version of the spatial object was inserted or changed in the spatial data set.

Multiplicity: 1

Stereotypes: voidable

Valuetype: DateTime

Definition: Date and time at which this version of the spatial object was superseded or retired in the spatial data set.

Multiplicity: 0...1

Stereotypes: voidable

Valuetype: DateTime

Definition: The period when the statistical unit is supposed to be preferably used and not.

Multiplicity: 0...1

Valuetype: TM_Period

Definition: The period when the data is supposed to give a picture of the territorial division in statistical units.

Multiplicity: 1

Valuetype: TM_Period


Constraints

Type OCL

Status Approved

Note /* Vector statistical units with a reference geometry instance of GM_MultiSurface must be instances of the specialised class AreaStatisticalUnit. */


Associated objects - Mandatory

Definition: A geometrical representation for vector statistical units.

Description: Vector statistical units can have several representations depending on the context they are used for. It is adviced to produce at least one reference geometry.EXAMPLE1: A vector statistical units may be represented both by an area and a point geometry. Such point can be the center of gravity or a label location.EXAMPLE2: For mapping, different generalised representations of vector statistical units are required. These geometries depend on the visualisation scale.

Multiplicity: 1..*

Name of the association: geometry

Association definition: Geometrical representations of the vector statistical unit.
