A scope in Collibra Data Intelligence Platform is a selection of communities and domains that you can refer to in an assignment of an asset type. Each community or domain belongs to exactly one scope.
Default scope and custom scopes
Collibra always has a default scope. Initially, all communities and domains are part of the default scope.
Depending on your requirements, you can create custom scopes and add specific communities and domains to it. If you add a community or domain to a custom scope, it is no longer part of the default scope. If you delete a custom scope, or remove communities and domains from a custom scope, the affected communities and domains revert to the default scope.
For more information about scopes after an upgrade from version 4.x to 5.x, see Collibra Support Portal.
