TTL - Concept
Unit of thought created by a unique combination of characteristics.
At an abstract level, a Concept is defined in the Generic Statistical Information Model (GSIM) as a "unit of thought differentiated by characteristics". Concepts are used in different ways throughout the statistical lifecycle, and each role of a Concept is described using different information objects (which are subtypes of Concept). A Concept can be used in these situations:
(a) As a characteristic. The Concept is used by a Variable to describe the particular characteristic that is to be measured about a Population. For example, to measure the Concept of gender in a population of adults in Spain, the Variable combines this Concept with the Unit Type "person".
(b) As a Unit Type or a Population. To describe the set of objects that information is to be obtained about in a statistical survey. For example, the Population of adults in the Netherlands based on the Unit Type of persons.
(c) As a Category to further define details about a Concept. For example, Male and Female for the Concept of Gender. Codes can be linked to a Category via a Node (i.e. a Code Item or Classification Item), for use within a Codelist or Statistical Classification.
In SDMX the Concept can be given a core Representation such as a reference to a Codelist for an enumerated Representation or other values such as "integer" or "string" for a non-enumerated Representation. This Representation can be overridden in the data structure when the Concept is used as a Dimension or Attribute. A Concept with a core Representation could be regarded as a represented variable.
