235 -The ConceptScheme can have one or more [[Concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]]. A [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] can have zero or more child [[Concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]], thus supporting a [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]] of [[Concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]]. Note that a child [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] can have only one parent [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] in this association. The purpose of the [[hierarchy>>doc:sdmx:Glossary 2\.1.Hierarchy.WebHome]] is to relate [[concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] that have a semantic relationship: for example, a Reporting_Country and Vis_a_Vis_Country may both have Country as a parent [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]], or a [[CONTACT>>doc:sdmx:Glossary 2\.1.Contact.WebHome]] may have a PRIMARY_CONTACT as a child [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]]. It is not the purpose of such schemes to define reporting structures: these reporting structures are defined in the MetadataStructureDefinition.

237 -The [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] can be associated with a coreRepresentation. The coreRepresentation is the specification of the format and value domain of the [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] when used on a structure like a DataStructureDefinition or a MetadataStructureDefinition, unless the specification of the [[Representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] is overridden in the relevant structure definition. In a hierarchical ConceptScheme the [[Representation>>doc:sdmx:Glossary 2\.1.Representation.WebHome]] is inherited from the parent [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] unless overridden at the [[level>>doc:sdmx:Glossary 2\.1.Level.WebHome]] of the child [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]].
