--Constraints are, effectively, lists of the valid or actual content of data and metadata. Constraints can be used to specify a subset of the theoretical content of data set or metadata set which can be derived from the specification of the DSD or MSD.

--Constraints comprise the specification of subsets of key or attribute values that are to be provided for a Dataflow or Metadataflow, or directly attached to a Data Structure Definition or Metadata Structure Definition. This is important metadata because, for example, the full range of possibilities which is implied by the Data Structure Definition (e.g., the complete set of valid keys is the Cartesian product of all the values in the code lists for each of the Dimensions) is often more than is intended to be supplied according to a specific Dataflow.

--A Data Provider has published a new dataset conforming to an existing Dataflow (and hence Data Structure Definition).

--The Data Provider wishes to make this new data available to one or more data collectors in a “pull” scenario, or to make the data available to data consumers. To do this, the Data Provider registers the new dataset with one or more SDMX conformant registries that have been configured with structural and provisioning metadata.
