The objective of the paper was to expound the main process of metadata technology and method applied in the construction of soil and water monitoring information system. Firstly the paper defined contents of rectadata
including basic metadata and business metadata
among of them
the basic metadata were used to manage the data stored in the database and mainly to describe the information about data
and the business metadata helped system to implement the function of update and inquiry of data. Secondly the paper expounded in details contents and purposes of two types of metadata and described how to organize and store these metadata. Finally
the flow chart of management of metadata was proposed
and functions of creation and management of metadata were integrated into the management and update system for information platform
then the synchronous management for metadata and their data was realized for the system.
