Abstract: The invention comprises a computer-based method for automatically generating a user interface (“UI”) and an application program interface (“API”) that can be used by TCP/IP network administrators. Embodiments herein send a query to a network device seeking metadata for each of the attributes supported thereon. When an answer is returned, which in some embodiments can be sent to devices supporting a Redfish protocol, the response is used to populate a relational database containing metadata for the device, as well as each attribute supported thereon. This metadata is organized in a hierarchical relational database, which is then used to automatically generate a user interface and an application program interface. The user interface and the application program interface are used to manage the settings on the network device. The user interface and application program interface or created using a proprietary data modeling language that is easy to use because it eliminates the need to code every action.
