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).COMMON_UNIT_SHARE" id="COMMON_UNIT_SHARE"><com:Annotations><com:Annotation><com:AnnotationType>CONTEXT</com:AnnotationType><com:AnnotationText xml:lang="en">This indicator is used when administrative data are combined with survey data in such a way that data on unit level are obtained from both the survey and one or more administrative sources (some variables come from the survey and other variables from the administrative data) or when data for part of the units come from survey data and for another part of the units from one or more administrative sources. The indicator provides an idea of completeness/coverage of the sources - to what extent units exist in both administrative data and survey data.</com:AnnotationText></com:Annotation><com:Annotation><com:AnnotationType>TYPE</com:AnnotationType><com:AnnotationText xml:lang="en">Cross-domain concept</com:AnnotationText></com:Annotation><com:Annotation><com:AnnotationType>RECOMMENDED_REPRESENTATION</com:AnnotationType><com:AnnotationText xml:lang="en">String</com:AnnotationText></com:Annotation><com:Annotation><com:AnnotationType>RELATED_TERMS</com:AnnotationType><com:AnnotationText xml:lang="en">Coverage error; Over-coverage rate; Processing error</com:AnnotationText></com:Annotation><com:Annotation><com:AnnotationType>SOURCE</com:AnnotationType><com:AnnotationText xml:lang="en">Eurostat "ESS Guidelines for the Implementation of the ESS Quality and Performance Indicators (QPI)", Luxembourg, 2014 (http://ec.europa.eu/eurostat/documents/64157/4373903/02-ESS-Quality-and-performance-Indicators-2014.pdf/5c996003-b770-4a7c-9c2f-bf733e6b1f31)</com:AnnotationText></com:Annotation></com:Annotations><com:Name xml:lang="en">Proportion of common units</com:Name><com:Description xml:lang="en">Proportion of units covered by both the survey and the administrative sources in relation to the total number of units in the survey.</com:Description></str:Concept></str:ConceptScheme></str:ConceptSchemes></message:Structures></message:Structure>
