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_VALIDATION" id="STRUCT_VALIDATION"><com:Annotations><com:Annotation><com:AnnotationType>CONTEXT</com:AnnotationType><com:AnnotationText xml:lang="en">In part the validation can be performed by processes that check the syntax of the data for conformance with the standard, for example a process for validating an XML instance (e.g. an SDMX data set) against the XML schema that defines the allowable structure and content of the instance. In SDMX the structural metadata contain additional metadata that can be used for validation but which cannot be expressed in an XML schema. Examples of these additional metadata include Constraints and Data Providers. The Constraint is used to specify the codes that are contained in a code list and which are valid for the type (sub set) of data that are to be expressed in data set in given context. The Data Provider specifies which type of data is expected or allowed to be reported or disseminated by a specific individual or organisation.</com:AnnotationText></com:Annotation><com:Annotation><com:AnnotationType>RELATED_TERMS</com:AnnotationType><com:AnnotationText xml:lang="en">Reference metadata; Structural metadata</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 validation</com:Name><com:Description xml:lang="en">Process to determine the validity of data and reference metadata using structural metadata.</com:Description></str:Concept></str:ConceptScheme></str:ConceptSchemes></message:Structures></message:Structure>
