IREF329815false2026-05-13T00:43:02ZSDMX 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.CONTEXTA constraint can be of a variety of types. For example, a Content Constraint specifies either the "allowable content" (used to restrict the values allowed when data or metadata are reported or exchanged), or the "actual" content (series keys and/or dimension and attribute values present in a data source). In each of these cases the constraint specifies a sub set of the full cube of data that could theoretically be present according to the specification of the Data Structure Definition or Metadata Structure Definition.RELATED_TERMSAttribute; Code; Code list; Member selection; Member value; Metadata key set; Metadata key valueSOURCESDMX (2016) (https://sdmx.org/)ConstraintSpecification of a subset of the possible content of data or metadata that can be derived from the code lists used in a data or metadata structure.
