GB/T 19488.2-2008

This standard defines a directory of common data elements for use in Chinese e-government systems, specifying standardized names, definitions, data types, and formats for frequently exchanged information such as personal names, addresses, and identification numbers. It is applied across government information systems and inter-agency data sharing platforms to ensure semantic consistency and interoperability when processing administrative services, public records, or cross-departmental transactions. The standard primarily supports system integration and data exchange in China's electronic government infrastructure.
