156 156  A “cube” is a rich, multi-dimensional construct, which can be viewed along any of its axes (or “[[dimensions>>doc:sdmx:Glossary.Dimension.WebHome]]”). Whilst the full structure of cube data can be described in [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]], the actual “data” specification of [[SDMX>>doc:sdmx:Glossary.Statistical data and metadata exchange.WebHome]] takes a slightly narrower view of these requirements in its (% style="color:#e74c3c" %)version(%%) 2.0/2.1 specifications for the purposes of formatting the data for transmission.

162 162  Further, there is support for the expression of functional dependencies between the various [[dimensions>>doc:sdmx:Glossary.Dimension.WebHome]] of a cube, giving support for better processing of “sparse cubes”. This is an aspect of “(% style="color:#e74c3c" %)constraints(%%)”, which allow for the framing of a cube region, or for the provision of a set of valid keys within the total set of keys described by the [[data structure definition>>doc:sdmx:Glossary.Data structure definition.WebHome]].

166 166  Metadata structures are based on the idea that (% style="color:#e74c3c" %)concepts(%%) can be organised into semantic and presentational [[hierarchies>>doc:sdmx:Glossary.Hierarchy.WebHome]], and that these [[hierarchies>>doc:sdmx:Glossary.Hierarchy.WebHome]] can form the basis for the structuring of XML reporting formats. There are three message types in [[SDMX-ML>>doc:sdmx:Glossary.SDMX-ML.WebHome]] which serve this purpose: the Structure message (providing the [[metadata structure definition>>doc:sdmx:Glossary.Metadata structure definition.WebHome]]), the Generic Metadata message (providing a single format for any [[metadata structure definition>>doc:sdmx:Glossary.Metadata structure definition.WebHome]]), and the Structure-specific Metadata message (providing a [[metadata structure definition>>doc:sdmx:Glossary.Metadata structure definition.WebHome]]-specific format). Typically, this mechanism is suited to supporting [[reference metadata>>doc:sdmx:Glossary.Reference metadata.WebHome]] reporting and dissemination.
