Description and main purpose of the software

Fusion Metadata Registry is a free to use structural metadata registry to the SDMX specification for authoring, maintaining, storing and exchanging structural metadata including Data Structure Definitions, Codelists and Concepts.

The software is supplied as a Java web application meaning that it will run on Windows, Linux and Apple Mac, and other computing platforms with a suitable Java runtime environment and Java web application server. Its web user interface can be accessed using standard web browsers. Docker images are also available to simplify deployment and for those operating containerised environments.

Key use cases:

Structural metadata management

  • Centralise and control SDMX structural metadata
  • Author and maintain SDMX structural metadata
  • Provide the metadata for ‘metadata-driven’ statistics production processes
  • Publish structural metadata on a SDMX-compliant REST structure API

Statistics production

  • Validate data for compliance with structural metadata, constraints and business rules (not VTL)
  • Execute complex data mapping using SDMX structure maps (not VTL)
  • Convert data between SDMX formats

Data collection

  • Collect data using Excel forms
  • Map incoming data into standardised SDMX structures

Data reporting

  • Prepare SDMX data for reporting
  • Validate data for compliance with the data collector’s specifications prior to reporting
