The Euro-SDMX registry is a metadata registry which implements the SDMX registry specifications. It provides a web-based user interface as well as web services for interacting with the SDMX structural metadata objects in use within Eurostat and with statistical partners. It will enable National Statistics Institutes and other external organisations to obtain Data Structure Definitions (DSD) and other structural metadata, such as the Metadata Structure Definitions (MSD) for the Euro-SDMX Metadata Structure (ESMS).

The business vision for SDMX envisages a "data sharing" model to facilitate data and metadata exchange. The SDMX Registry is tasked with providing structure, organisation, and maintenance and query interfaces for most of the SDMX components required to support the data sharing vision. The "data sharing" model is based on the possibility of discovering easily where data and metadata are available and how to access them. The SDMX Registry plays an important role in this architecture, in fact it can be seen as a central application which is accessible to other programs over the Internet (or an Intranet or Extranet) to provide information needed to facilitate the reporting, collection and dissemination of statistics. In its broad terms, the SDMX Registry – as understood in web services terminology – is an application which stores metadata for querying, and which can be used by any other application in the network with sufficient access privileges. It can be seen as the index of a distributed database or metadata repository which is made up of all the data provider’s data sets and reference metadata sets within a statistical community. It is important to stress that registry services are not concerned with the storage of data or reference metadata sets. Data and metadata sets are stored elsewhere, on the sites of the data providers. The registry is only concerned with providing information needed to access the data and reference metadata sets. An application which wants a particular data or metadata set would then query the registry for the URL, and then go and retrieve the data or metadata set directly from the provider's web server.

The SDMX registry specifications define the logical interfaces for the SDMX registry in terms of the functions required and the data that may be present in the function call, and the behaviour expected of the registry and normative rules regarding the Registry Interface and the identification of registry objects.

The Euro-SDMX Registry can be reached via its web graphical user interface at It provides the registry web services according to the SDMX Version 2.0 standards. Eurostat has also deployed a training instance of the Registry, which can be used as a "sandbox" for training courses and presentations, without the risk of modifying the real registry. Access to the training environment can be provided on request.
