Abstract

The paper examines how to establish metadata standard and metadata management system of National Resource and Environment Spatial Database. It also discusses some issues concerning the construction of metadata database of National Resource and Environment Database. In the construction, low quality of metadata results in depression of metadata's function and acquirability of the datum. Additionally, this paper gives a new direction of metadata-base research. According to multi-layer metadata model, it combines extensible metadata model with inhomogeneous metadata to improve metadata quality. This paper also puts forward a method that can make metadata-based service convert from passive mode to initiative mode.

Key words： metadata; metadata standards; metadata management system; data quality; initiative service
