Population

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

Definition

Universe with time and geography specified.

Examples

  1. Canadian adult persons residing in Canada on 13 November 1956.

  2. US computer companies at the end of 2012.

  3. Universities in Denmark 1 January 2011.

Explanatory notes

Population is the most specific in the conceptually narrowing hierarchy of unit type, universe and population. Several populations having differing time and or geography may specialize the same universe.

Description

Default value

timePeriodOfPopulation

- own class -

The time period associated with the population.

DateRange

0..*

isInclusive

Conceptual::Universe

Default value is True. The description statement of a universe is generally stated in inclusive terms such as “All persons with university degree”. Occasionally a universe is defined by what it excludes, i.e., “All persons except those with university degree”. In this case the value would be changed to False.

Boolean

true

descriptiveText

Conceptual::UnitType

A short natural language account of the characteristics of the object.

InternationalString

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.

CatalogDetails

definition

Conceptual::Concept

Natural language statement conveying the meaning of a concept, differentiating it from other concepts. Supports the use of multiple languages and structured text. ‘externalDefinition’ can’t be used if ‘definition’ is used.

InternationalString

0..1

displayLabel

Conceptual::Concept

A human-readable display label for the object. Supports the use of multiple languages. Repeat for labels with different content, for example, labels with differing length limitations.

0..*

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.

Reference

identifier

Conceptual::Concept

Identifier for objects requiring short- or long-lasting referencing and management.

Identifier

name

Conceptual::Concept

Human understandable name (linguistic signifier, word, phrase, or mnemonic). May follow ISO/IEC 11179-5 naming principles, and have context provided to specify usage.
