An integrated geospatial metadata storing architecture

With the widespread of the concept and implementation of Web Services, more types of data need to be shared. To facilitate the discovering and sharing of geospatial data sets and geospatial Web services, this paper presents an integrated storing architecture for geospatial metadata. With this architecture, metadata for geospatial data and geospatial Web services can be manipulated in a unified way. Also, this architecture provides a practical way to build the Geospatial Portal, which can be further integrated into the digital city to facilitate the discovering and integration of geospatial resources
