Abstract
Abstract In a distributed data processing system comprising a plurality of different computer systems, each system having a central processing unit (CPU), memory, a database stored in the memory, and a DBMS, a computerized method is provided for generating a plurality of objects in a standardized format. A unique object identifier is associated with each of the plurality of objects. Each unique object identifier is stored in memory in association with at least one object location type or instance, an object generation specification for each object location type or instance, and a generation specification type. For a requested object type at a specified location, identifying from the computer memory an object generation specification, and a specification type. The requested object is generated in a standardized format from the specified location using the identified process type and the identified object generation specification.
