393 -These guidelines define the standard set of [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] [[Concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] Roles and their use. This set of standard [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] [[Concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] are implemented as a [[cross-domain Concept>>doc:sdmx:Glossary 2\.1.Cross-domain concept.WebHome]] Scheme that defines the set of [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] roles and gives examples on [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] role implementation in [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] 2.0, 2.1 and 3.0. A [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] role gives a particular context to a [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] for easy and systematic interpretation by machine processing and visualization tools. For example, the [[concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] REPORTING_AREA and COUNTERPART_AREA are different [[concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] but they are both geographical characteristics, therefore they can be associated with the same [[concept>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] role ID: "GEO". This allows visualization systems to interpret these [[concepts>>doc:sdmx:Glossary 2\.1.Concept.WebHome]] as geographical data in order to generate [[maps>>doc:sdmx:Glossary 2\.1.Map.WebHome]].

Specifically for [[SDMX>>doc:sdmx:Glossary 2\.1.Statistical data and metadata exchange.WebHome]] 3.0, this set of roles is considered a normative list that must be interpreted in the same way by all organisations.
