Structure Set

A Structure Set is a maintainable collection of Structure Maps that link Components together in a source/target relationship where there is a semantic equivalence between the source and the target Components.

There are two main types of Structure Map
Maps between item schemas

• Codelist Map
• Concept Scheme Map

Maps to change the dimensionality of datasets

• Data Structure Map
• Dataflow Map

A typical use of Structure Sets is to provide mappings between an SDMX data structure used in an internal system with an SDMX structure of an external dataset when imported to or exported from the internal system. The internal Data Structure Definition of a dataset is sometimes too complex for public dissemination. In this case, Structure Maps can be used to map to a Data Structure Definition with fewer dimensions and attributes.
