Overview

A Category Scheme is a container for Categories. An example of a category scheme is one which categorises data - sometimes known as subject matter domain scheme or a data category scheme. The individual Categories can be associated to any set of identifiable Artefacts in a Categorisation.

Structure Properties

Structure Type Standard SDMX Structural Metadata Artefact
Maintainable Yes
Identifiable Yes
Item Scheme Yes
SDMX Information Model Versions 2.0, 2.1
URN - CategoryScheme namespace urn:sdmx:org.sdmx.infomodel.categorycheme.CategoryScheme
URN - categorisation namespace urn:sdmx:org.sdmx.infomodel.categorycheme.Categorisation

Context within the SDMX 2.1 Information Model

L CategoryScheme.png

The schematic illustrates the core artefacts of the SDMX 2.1 Information Model, and how Category Schemes, Categorys and Categorisations fit in.

Usage

Concepts are used by Dimensions, Attributes, Measures, and Metadata Attributes to provide them with a semantic meaning. Concepts can also be used to define a default representation, for example it is possible to link the Concept of Frequency to a Codelist containing all the Frequency Codes, and any structure using the Concept will inherit the default representation.

The SDMX Cross Domain Concept Scheme provides a range of standardised Concepts maintained by the SDMX Statistical Working Group (SWG) and can be viewed on the Global Registry site https://registry.sdmx.org/items/conceptscheme.html.

Conventions

Concept Scheme IDs IDs are conventionally uppercase using underscores '_' as separators if required. Examples:

Agency Concept Scheme ID Description SDMX-ML
ESTAT CS_NA List of concepts for National Accounts DSDs SDMX-ML
UIS CS_BOP Balance of Payments Concept Scheme SDMX-ML
IMF CS_EDUC_UOE EDUC_UOE Concept Scheme SDMX-ML
SDMX CROSS_DOMAIN_CONCEPTS SDMX Cross Domain Concept Scheme SDMX-ML

Conventions

Category Scheme IDs IDs are conventionally uppercase using underscores '_' as separators if required. Examples:

Agency Category Scheme ID ID Description SDMX-ML
ESTAT ESA2010TP ESA 2010 - Transmission programme [ https://registry.sdmx.org/ws/public/sdmxapi/rest/categoryscheme/ESTAT/ESA2010TP/1.0 SDMX-ML]
SDMX STAT_SUBJECT_MATTER SDMX Statistical Subject-Matter Domains [ https://registry.sdmx.org/ws/public/sdmxapi/rest/categoryscheme/SDMX/STAT_SUBJECT_MATTER/1.0 SDMX-ML]
