As a public service platform ofgeographic information, National Geospatial Data Center (NGDC) can provide geospatial metadata services for data producers and data users. This paper firstly analyzes the problems in the development and maintenance of geospatial metadata deployment system. Then it describes and analyzes the characteristics of PHP framework and the advantages of developing content management system(CMS) with it.
