The description of the various types can be found in the chapter on ConceptScheme (section 4.5).

160 160  The //ItemScheme// is an abstract class which defines a set of //Item// (this class is also abstract). Its main purpose is to define a mechanism which can be used to create taxonomies which can classify other parts of the SDMX Information Model. It is derived from //MaintainableArtefact// which gives it the ability to be annotated, have identity, naming, versioning and be associated with an Agency. An example of a concrete class is a ConceptScheme. The associated Concepts are //Item//s.
