A method and architecture is described that discovers software application metadata and generates data access applications based on the discovered software application metadata. The discovered metadata along with handcrafted metadata goes through a discovery process and is converted into common, generic abstract metadata objects. The abstract metadata objects then go through an instantiation process to be translated into concrete metadata objects that represent the unique configuration, context and terminology of the source software application. The concrete metadata objects can be generated into numerous forms for the purposes of data access and information sharing. The system also has upgrade protection.
