• all the items in the workspace are then associated with the domain, and they receive a domain attribute as part of their metadata [1]
• {benefit} enables a better consumption experience [1]
• simplify discovery and consumption 
• provide a management boundary between tenant and workspace enabling domain admins to have more granular control over multiple workspaces [6]
• some tenant-level settings for managing and governing data can be delegated to the domain level [2]
• allow to achieve federated governance [7]
• by delegating settings to domain admins
• ⇒ allow provide more granular control over business area [7]
