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, known as a Categorisation.

Structure Properties

Structure Type Standard SDMX Structural Metadata Artefact

SDMX Information Model Versions 2.0, 2.1

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

Usage

Categories are used within a Category Scheme and has the facility to have one or more child codes as well as being multi-lingual.

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.

More information on Category schemes can be found in this article.

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

You can seem more examples and information on Identities in this article.
