IREF330230false2026-05-13T00:43:48ZSDMX Cross Domain Concept SchemeThe Cross Domain Concept Scheme (starting from v2.0) is created from the set of concepts in the SDMX Glossary, which is an SDMX guideline containing concepts and related definitions that are useful for building and understanding data and metadata exchange arrangements based on SDMX. The Glossary provides definition of terms found in the SDMX Information Model, Data Structure Definitions (DSDs) and Metadata Structure Definitions (MSDs) at the time of the present release. It is recommended as a single entry point to a common SDMX terminology to be used in order to facilitate communication and understanding of the standard.In short, the overall message of the glossary is the following: if a term is used, then its precise meaning should correspond to the SDMX Glossary definition, and any reference to a particular phenomenon described in the SDMX Glossary should use the appropriate term.Version 1.0 of the SDMX Glossary, which replaces the Metadata Common Vocabulary (MCV) published in 2009, was finalised in February 2016. The Cross Domain Concept Scheme v1.0 was created from the MCV concepts.For any question, comment or correction, feel free to contact the SDMX Statistical Working Group (SWG) at the following address: swg@sdmx.org.CONTEXTThe Category can link to any identifiable object and can help discovery of structural metadata. In a data dissemination or data collection system the Category will probably link to a Dataflow or Metadataflow to support data or metadata discovery or data or metadata collection management. The Category can link to multiple identifiable objects and any identifiable object can link to multiple categories, possibly in different category schemes. The link between a single category and a single identifiable object is contained in a Categorisation.RELATED_TERMSCategory scheme; Dataflow; MetadataflowSOURCESDMX (2016) (https://sdmx.org/)CategoryStructural metadata concept that classifies structural metadata objects.
