IREF498895false2026-05-13T05:24:46ZSDMX 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 statistical agencies, the domain manager is often asked to certify that the metadata are checked and updated at regular time intervals. The date of the latest certification is to be retained. The concept is relevant for metadata reporting from countries to international organisations within metadata standards initiatives.TYPECross-domain conceptRECOMMENDED_REPRESENTATIONDateTimeRELATED_TERMSMetadata update; Metadata update - last posted; Metadata update - last updateSOURCESDMX (2016) (https://sdmx.org/)Metadata update - last certifiedDate of the latest certification provided by the domain manager to confirm that the metadata posted are still up-to-date, even if the content has not been amended.
