IREF330229false2026-05-13T00:43:47ZSDMX 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.CONTEXTIn SDMX, data sets are reported or disseminated according to a data flow definition. The data flow definition identifies the data structure definition and may be associated with one or more subject-matter domains. This facilitates the search for data according to organised category schemes. A "Dataflow", in this context, is an abstract concept of the data sets, i.e. a structure without any data. While a data structure definition defines dimensions, attributes, measures and associated representation that comprise the valid structure of data and related metadata contained in a data set, the Dataflow definition associates a data structure definition with one or more category. This gives a system the ability to state which data sets are to be reported for a given category and which data sets can be reported using the data structure definition. The Dataflow definition may also have additional metadata attached, defining qualitative information and constraints on the use of the data structure definition, in terms of reporting periodicity or specifying the subset of codes to be used in a dimension.RELATED_TERMSAttribute; Category; Data set; MetadataflowSOURCESDMX (2016) (https://sdmx.org/)DataflowStructure which describes, categorises and constrains the allowable content of a data set that providers will supply for different reference periods.
