Key Technology for Data Catalog System

E-government information resources integration based on catalog system are beneficial to the sharing and exchange of information resources. According to the characteristics of the natural resources and geo-spatial information resources, the paper analyzed the catalog system of e-government resources, and then put forward the data catalog system of the natural resources and geo-spatial information resources integration transformation to deal with synthesis decision-making. This integrated approach establishes the basis of the organic integration of information resources, and adapts to the dynamic changes of information resources. At the same time, through cataloging, it can make data providers and share sectors clear, and provides the establishment of long-term mechanism for the integration and sharing of information resources.
