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>>doc:Glossary.SDMX Information Model.WebHome]]. It is derived from //[[MaintainableArtefact>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.WebHome]]// which gives it the ability to be annotated, have identity, naming, versioning and be associated with an [[Agency>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.Item.Organisation.Agency.WebHome]]. An example of a concrete class is a [[ConceptScheme>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.VersionableArtefact.MaintainableArtefact.ItemScheme.ConceptScheme.WebHome]]. The associated Concepts are //[[Item>>doc:IMElements.AnnotableArtefact.IdentifiableArtefact.NameableArtefact.Item.WebHome]]//s.
