US Patent 10911454 Hierarchical case model access roles and permissions

Hierarchical case model access roles and permissions are described. A system creates, for a child node associated with a parent node in a case model, a reference to a case role associated with the parent node. The system assigns another set of access permissions to the reference. The system determines access to the child node based on the set of access permissions in response to a request associated with the case role to access the child node.
