The version 3.0 information model provides four [[item scheme>>doc:sdmx:Glossary 2\.1.Item scheme.WebHome]] maps: organisation scheme map, [[concept scheme>>doc:sdmx:Glossary 2\.1.Concept scheme.WebHome]] map, [[category scheme>>doc:sdmx:Glossary 2\.1.Category scheme.WebHome]] map and [[reporting taxonomy>>doc:sdmx:Glossary 2\.1.Reporting taxonomy.WebHome]] map.

  * //**[[Reporting Taxonomy>>doc:sdmx:Glossary 2\.1.Reporting taxonomy.WebHome]]: **//A [[reporting taxonomy>>doc:sdmx:Glossary 2\.1.Reporting taxonomy.WebHome]] allows an organisation to link (possibly in a hierarchical way) a number of cube or [[data flow>>doc:sdmx:Glossary 2\.1.Dataflow.WebHome]] definitions which together form a complete “report” of data or metadata. This supports primary reporting which often comprises multiple cubes of heterogeneous data, but may also support other collection and reporting functions. It also supports the specification of publications such as a yearbook, in terms of the data or metadata contained in the publication.
  * //**Process:**// The process class provides a way to model statistical processes as a set of interconnected //process steps.// Although not central to the exchange and dissemination of statistical data and metadata, having a shared description of processing allows for the interoperable exchange and dissemination of [[reference metadata>>doc:sdmx:Glossary 2\.1.Reference metadata.WebHome]] sets which describe processes-related (% style="color:#e74c3c" %)concepts(%%).

The [[codes>>doc:sdmx:Glossary 2\.1.Code.WebHome]] themselves are referenced from the [[code lists>>doc:sdmx:Glossary 2\.1.Code list.WebHome]] in which they are maintained.
