Establishes a framework for coordinating the development of existing and future standards for the management of persistent data in information systems. Defines common terminology and concepts pertinent to all data held within information systems. Includes consideration of standards for the management of data located on one or more computer systems, including services for distributed database management. Does not specify services and protocols for data management.
