Permission Schema is a way to organize application access control. All access control settings can be organized in Permission Schemas. Different Permission Schemas can have their own, completely different set of access rules. Simply by switching active Permission Schema, access control in the system can be reconfigured in a moment. Thus, only one schema can be active in the system.
In the form there is a list of existing schemas in the system. Permission schema can be added, set active, edited or deleted. System default schema cannot be edited or deleted.
