The Research of Meteorological Metadata Standard and Information Issuing

Metadata is making an important effect on the data exchange, information search in Web and sharing system design. The up-to-date development of metadata and metadata standards is introduced concisely. The establish principle, gist and content of our metadata standard are emphasized. The architecture and flow of metadata system are explored. At last, based on the layout and developing practice of "Meteorological Data Sharing Project", the blue print and implement of metadata issuing system for the China Meteorological Data Service Network are expounded in detail.
