UnitType

Fully qualified class name: DDICDIModels::DDICDILibrary::Classes::Conceptual::UnitType

Definition

Unit type is a type or class of objects of interest (units).

Examples

Person, Establishment, Household, State, Country, Dog, Automobile, Neutrino.

Explanatory notes

Unit type is the most general in the hierarchy of unit type, universe, and population. It is a description of the basic characteristics for a general set of Units. A universe is a set of entities defined by a specialization of a unit type. A Population further narrows the specification to a specific time and geography.

A unit type is used to describe a class or group of Units based on a single characteristic with no specification of time and geography. For example, the unit type of “Person” groups together a set of Units based on the characteristic that they are “Persons”.

It concerns not only unit types used in dissemination, but anywhere in the statistical process. E.g. using administrative data might involve the use of a fiscal unit. [GSIM 1.1].

catalogDetails

Conceptual::Concept

Bundles the information useful for a data catalog entry. Examples would be creator, contributor, title, copyright, embargo, and license information. A set of information useful for attribution, data discovery, and access. This is information that is tied to the identity of the object. If this information changes the version of the associated object changes.

externalDefinition

Conceptual::Concept

A reference to an external definition of a concept (that is, a concept which is described outside the content of the DDI-CDI metadata description). An example is a SKOS concept. The definition property is assumed to duplicate the external one referenced if externalDefinition is used. Other corresponding properties are assumed to be included unchanged if used.
