RepresentedVariable

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

Definition

Conceptual variable with a substantive value domain specified.

Examples

The pair (Number of Employees, Integer), where “Number of Employees” is the characteristic of the population (variable) and “Integer” is how that measure will be represented (value domain).

Explanatory notes

Extends from conceptual variable and can contain all descriptive fields without creating a conceptual variable. By referencing a conceptual variable it can indicate a common relationship with represented variables expressing the same characteristic of a universe measured in another way, such as Age of Persons in hours rather than years. Represented variable constrains the coverage of the unit type to a specific universe. In the above case the universe with the measurement of Age in hours may be constrained to Persons under 5 days (120 hours old). Represented variable can define sentinel values for multiple storage systems which have the same conceptual domain but specialized value domains.

Description

Data Type

Multiplicity

Default value

describedUnitOfMeasure

- own class -

The unit in which the data values are measured (kg, pound, euro), expressed as a value from a controlled system of entries (i.e., QDT). Supports the provision of an identifier for the entry in the authoritative source (a URI, etc.), and the specific vocabulary.

ControlledVocabularyEntry

0..1

hasIntendedDataType

- own class -

The data type intended to be used by this variable. Supports the optional use of an external controlled vocabulary.

ControlledVocabularyEntry

0..1

simpleUnitOfMeasure

- own class -

The unit in which the data values are measured (kg, pound, euro), expressed as a simple string, in cases where no additional information is available (in the legacy system) or needed (as in the case of broad agreement within the community of use [i.e., ISO country codes, currencies, etc. in SDMX])

String

descriptiveText

Conceptual::ConceptualVariable

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

InternationalString

0..1

unitOfMeasureKind

Conceptual::ConceptualVariable

Kind of unit of measure, so that it may be prone to translation to equivalent UOMs. Example values include “acceleration,” “temperature,” “salinity”, etc. This description exists at the conceptual level, indicating a limitation on the type of representations which may be used for the variable as it is made more concrete.

ControlledVocabularyEntry

0..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.

CatalogDetails

0..1

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

0..1

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.

RepresentedVariable takesSentinelValuesFrom SentinelValueDomain

A represented variable may have more than one sets of sentinel value domains, one for each type of software platform on which related instance variables might be instantiated. All of the sentinel value domains must have sentinel conceptual domains that correspond exactly. This allows codes for missing values to be explicitly matched across platforms.

By referencing a conceptual variable it can indicate a common relationship with represented variables expressing the same characteristic of a universe measured in another way, such as Age of Persons in hours rather than years. Represented variable constrains the coverage of the unit type to a specific universe. In the above case the universe with the measurement of Age in hours may be constrained to Persons under 5 days (120 hours old). Represented variable can define sentinel values for multiple storage systems which have the same conceptual domain but specialized value domains."@en;
