An SDMX Registry is a repository for the maintenance, storage, and dissemination of a specific type of metadata called ‘Structural Metadata’. Structural metadata can be used to describe the structure of datasets in any statistical domain. It is also used to describe the collection and dissemination of data and associated metadata. Structural metadata can also be used to describe rules and restrictions for data providers reporting datasets, it can describe statistical process, and help categorise datasets.
The purpose of an SDMX Registry is to act as a single point of access for structural metadata within an organisation, or between organisations. Although an SDMX Registry does not store datasets they provide a mechanism to identify where the datasets are located, this means an SDMX Registry describes datasets independently of how the data are stored.
The Fusion Registry is an implementation of an SDMX Registry, as described by the SDMX Specification.
