Abstract
A computer-based uniform data interface (UDI) system for accessing in a uniform manner data from a data source with an arbitrary organization. The UDI system provides a UDI application programming interface (API) with functions for creating and accessing data organized into containers that contain one or more folders. Each folder optionally contains sub-folders and scalars. The UDI system also provides a UDI registry for registering types of containers and folders supported by a data source, for enumerating the types of containers and folders supported by the data source, and for instantiating container and folder objects corresponding to the data of the data source. A UDI mapper is provided for registering with the UDI registry types of containers and folders that represents the data of the data source, for instantiating in memory container and folder objects of the registered types, and for populating an instantiated container object with folders representing the data from the data source that is within the container. An application program invokes the UDI API functions to access data of data sources with arbitrary organizations.
