The sdmx.io ecosystem includes a collection of open source SDMX software tools cooperating to solve official statistics use cases.
Fusion Metadata Registry (FMR) is primarily a structural metadata registry - a database designed specifically for storing SDMX artefacts including Concepts, Codelists and Data Structure definitions. A registry is useful in many cases where statistics are collected, produced and exchanged for externalising, centralising and controlling the structural metadata.
Benefits of using a registry for managing structural metadata include:
FMR provides several additional features in addition to its core registry role that help to support practical use cases:
FMR’s web user interface provides metadata managers and data modellers with a graphical way to explore the registry’s content, create new structures and maintain existing ones.
Many artefacts can also be exported to Excel, modified and reloaded - particularly useful for maintaining large Codelists and Constraints.
Datasets can be loaded and validated - checked that they comply with the Checking data quality helps to deliver effective data governance and improves the efficiency of data exchanges, avoiding the costly re-processing or re-transmission.
FMR applies nine standard validation rules:
|The XML, JSON, CSV or Excel is well formed
|Uniqueness - there is only one observation value reported for each time period
|All mandatory attributes are reported
|OBS_STATUS is consistent with the observation value
|Time period format
|E.g. FREQ=M means the TIME_PERIOD format must be YYYY-MM
|Balance equalities defined used Validation Schemes
|The data is within the universe defined by Data Constraints
|Each component complies with the representation defined in the DSD
|The dimensions and attributes are consistent with the DSD
Datasets can be converted between most SDMX formats including:
Datasets can be mapped (transformed) to different DSDs using SDMX Structure Mapping.
Typical use cases include:
FusionXL (FXL) is an Excel interface for FMR that complements and provides an alternative to the web user interface. The following functions are supported:
Fusion Transformer (FT) is a command line application for converting SDMX data between transmission formats. It provides an alternative to the FMR data conversion service finding application in scripts and data processing automation.
The .Stat Suite is a standard-based, componentised, open-source platform for the efficient production and dissemination of high-quality statistical data. It is:
The FMR Workbench (FWB) is a remote registry browser and metadata maintenance tool which brings the strengths and capabilities of the FMR User Interface to any SDMX compliant registry, implementing an SDMX RESTful API. One significant use case for FMR Workbench users is the ability to connect to .Stat-Suite spaces for browsing and maintaining .Stat-Suite structural metadata.
The SDMX Dashboard Generator (SDMX DG) is an open-source application that generates dynamic dashboards by offering several key features:
The application is co-winner of the SDMX Global Conference 2023 Hackathon.
Project ‘LinkageX’ (LinkageX) is the Swiss Army knife for SDMX. Aimed at data scientists and developers, LinkageX simplifies the use of SDMX data and metadata, enabling seamless integration and full utilization of the SDMX metamodel. This powerful Python-based toolkit streamlines SDMX-related workflows, enhancing data synchronization and harmonization efficiency and effectiveness.

The SDMX Test Compatibility Kit (SDMX TCK) is a tool for measuring the compliance and coverage of an SDMX RESTful endpoint against the available SDMX REST API versions.
