Abstract: A system for generating a data-driven user interface. The system comprises a network interface configured to communicate with a user device, a processor coupled to the network interface, and a memory coupled to the processor. The memory contains a product model, user-interface logic, and metadata. User interface specific metadata drives the user-interface logic to generate a dynamic user interface. The user-interface metadata defers to and is bound to the product model and comprises various abstractions including an item, set, frame and flow. A flow is responsive to one or more rules and defines a transition from a first frame to a subsequent frame.
