  Standard formats for the exchange of aggregated statistical data and metadata as prescribed in [[SDMX>>doc:Glossary.Statistical data and metadata exchange.WebHome]] v3.0 are envisaged to bring benefits to the statistical community because data reporting and dissemination processes can be made more efficient.

The [[SDMX>>doc:Glossary.Statistical data and metadata exchange.WebHome]] model supports interoperability, and it is important to be able to discover and share these [[artefacts>>doc:Glossary.Artefact.WebHome]] between parties in a controlled and organized way.

--Often a [[Data Provider>>doc:Glossary.Data provider.WebHome]] will not be able to provide data for all key combinations, either because the combination itself is not meaningful, or simply because the provider does not have the data for that combination.
