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.</com:Description><str:Concept urn="urn:sdmx:org.sdmx.infomodel.conceptscheme.Concept=SDMX:CROSS_DOMAIN_CONCEPTS(2.0).STRUCT_META" id="STRUCT_META"><com:Annotations><com:Annotation><com:AnnotationType>CONTEXT</com:AnnotationType><com:AnnotationText xml:lang="en">Structural metadata are needed to identify, use, and process data matrixes and data cubes, e.g. names of columns or dimensions of statistical cubes. Structural metadata must be associated with the statistical data and reference metadata, otherwise it becomes impossible to identify, retrieve and navigate the data or reference metadata. In SDMX structural metadata are not limited to describing the structure of data and reference metadata. The structural metadata in SDMX include many of the other constructs to be found in the SDMX Information Model including data discovery, data and metadata constraints (used for both data validation and data discovery), data and structure mapping, data and metadata reporting, statistical processes,</com:AnnotationText></com:Annotation><com:Annotation><com:AnnotationType>RELATED_TERMS</com:AnnotationType><com:AnnotationText xml:lang="en">Cross-domain concept, CDC; Reference metadata; Structural validation</com:AnnotationText></com:Annotation><com:Annotation><com:AnnotationType>SOURCE</com:AnnotationType><com:AnnotationText xml:lang="en">SDMX (2016) (https://sdmx.org/)</com:AnnotationText></com:Annotation></com:Annotations><com:Name xml:lang="en">Structural metadata</com:Name><com:Description xml:lang="en">Metadata that identify and describe data and reference metadata.</com:Description></str:Concept></str:ConceptScheme></str:ConceptSchemes></message:Structures></message:Structure>
