Load example SDMX structures

Overview
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 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.

- Choose the
Pull Structure
button - When prompted for Sync Options, choose
