Load example SDMX structures

From Fusion Registry Wiki
Jump to navigation Jump to search


SDMX structural metadata (structures for short) describe the data and need to be created before you can start working with the data itself. Structures in SDMX are equivalent to the empty tables and relationships in a SQL database before any data is inserted.

If you have access to structures in a suitable SDMX format like SDMX-ML (XML) or SDMX-JSON the you can start working immediately with those. Login using the admin account created at install and click the LoadStructuresOrReferenecMetadata.PNG button to load from file.

The rest of this guide explains how to download some example structures from Metadata Technology's cloud demonstration Fusion Registry service https://demo.metadatatechnology.com/FusionRegistry using the Environment Sync function.

Adding a Sync Environment

A Sync Environment is a remote Fusion Registry with which structures can be exchanged. In this case we're going to retrieve from structures from it.

  • Login using the admin account
  • From the left-hand menu choose Admin > Environments
  • Choose the Add Environments button and enter:
    • ID: Demo
    • URL: https://demo.metadatatechnology.com/FusionRegistry
  • Select the newly created 'Demo' environment in the list and choose the Sync Environment button
  • When prompted for a usernamed and password, click Sync Anonymously

Your Fusion Registry should connect to the demonstration service and retrieve a list of all available structures.

Next, download the SDMX Agency Scheme.

Download the Agency Scheme

In SDMX, each structure is owned by a specific Agency so we first need to download the Agency Scheme.

  • Click on Agency Schemes and check SDMX:AGENCIES (1.0) - SDMX Agency Scheme
  • Choose the Pull Structure button
  • When prompted for Sync Options, choose Selected structures only, and the Pull button
  • Acknowledge the report which should say that 1 structure has been created

Download all of the structures for the ECB External Trade dataflow (TRD)

For demonstration purposes we are going to download all of the structures needed for the ECB's External Trade dataflow, including Codelists, Concepts and the Data Structure Definition.

  • Click on Dataflows and check ECB:TRD (1.0) - External Trade
  • Choose the Pull Structure button
  • When prompted for Sync Options, choose Selected structures and descendents, and the Pull button
  • The report should tell us that a number of changes have been made to the Registry including 11 Codelists, plus a Concept Scheme, Data Structure Definition and a Dataflow
