SDMX/FMR: A reference SDMX Registry implementation

The FMR enables organisations to 'get a grip of their metadata', by externalising their statistical structural metadata with the benefits of maintainability, re-use, standardisation, harmonisation and improved metadata and data governance, achieved by:

  • A controlled repository for SDMX structural metadata, which acts as a single source of truth for: automated metadata-driven data processing systems, metadata needed by data providers in data collections, structures for the purposes of standardisation, statistical data harmonisation, and communal benefit. Implements the SDMX 3.0 Registry specification.
  • Three integrated metadata-driven data processing services: data validation, data transformation (mapping data between structures) and conversion of data between SDMX data formats. Usable through the web UI or integrated into data automation processes using the REST API.
  • Metadata authoring and maintenance web UI, enabling metadata managers to browse, author and maintain their structural metadata model.
