  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.
--As organisations migrate to [[SDMX>>doc:Glossary.Statistical data and metadata exchange.WebHome]] enabled systems, many XML, JSON (and conventional) [[artefacts>>doc:Glossary.Artefact.WebHome]] will be produced (e.g., Data Structure, Metadata Structure, [[Code List>>doc:Glossary.Code list.WebHome]] and (% style="color:#2ecc71" %)Concept(%%) definitions – often collectively called [[structural metadata>>doc:Glossary.Structural metadata.WebHome]] – XML schemas generated from [[data structure definitions>>doc:Glossary.Data structure definition.WebHome]], XSLT stylesheets for transformation and display of data and metadata, terminology references, etc.). 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.

--Given the above, the behaviour described in the following table concerns either draft [[Artefacts>>doc:Glossary.Artefact.WebHome]] using semantic versioning or any [[Artefacts>>doc:Glossary.Artefact.WebHome]] using the old versioning scheme. Nevertheless, in the case of semantic versioning the registry must respect the versioning rules when performing the actions below. For example, it is not possible to replace a non-draft [[Artefact>>doc:Glossary.Artefact.WebHome]] that follows semantic versioning, unless a newer (% style="color:#2ecc71" %)version(%%) is introduced according to the semantic versioning rules. Furthermore, even when draft [[Artefacts>>doc:Glossary.Artefact.WebHome]] are submitted, the registry has to verify semantic versioning is respected against the previous non-draft (% style="color:#2ecc71" %)versions(%%).

This is important metadata because, for example, the full range of possibilities which is implied by the [[Data Structure Definition>>doc:Glossary.Data structure definition.WebHome]] (e.g., the complete set of valid keys is the Cartesian product of all the values in the [[code lists>>doc:Glossary.Code list.WebHome]] for each of the [[Dimensions>>doc:Glossary.Dimension.WebHome]]) is often more than is actually present in any specific [[data source>>doc:Glossary.Data source.WebHome]], or more than is intended to be supplied according to a specific [[Dataflow>>doc:Glossary.Dataflow.WebHome]].

--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. In this case the [[Data Provider>>doc:Glossary.Data provider.WebHome]] could constrain the [[data source>>doc:Glossary.Data source.WebHome]] (at the (% style="color:#2ecc71" %)level(%%) of the [[Provision Agreement>>doc:Glossary.Provision agreement.WebHome]] or the [[Data Provider>>doc:Glossary.Data provider.WebHome]]) by supplying metadata that defines the key combinations or cube regions that are available.
