  * //**Organisation Scheme:**// Organisations and organisation structure can be defined in an Organisation Scheme. Specific Organisation Schemes exist for [[Maintenance Agency>>doc:sdmx:Glossary 2\.1.Maintenance agency.WebHome]], [[Data Provider>>doc:sdmx:Glossary 2\.1.Data provider.WebHome]], Metadata Provider, [[Data Consumer>>doc:sdmx:Glossary 2\.1.Data consumer.WebHome]], and Organisation [[Unit>>doc:sdmx:Glossary 2\.1.Statistical unit.WebHome]].

A [[Categorisation>>doc:sdmx:Glossary 2\.1.Categorisation.WebHome]] links a [[category>>doc:sdmx:Glossary 2\.1.Category.WebHome]] to an identifiable object. In this way sets of objects can be categorised.
