메타데이터 교환표준(XMI)을 이용한 분산 이종 GIS 데이터베이스 검색 = Distributed and Heterogeneous GIS Database Search using Metadata Interchange Standard(XMI)

다국어 초록 (Multilingual Abstract)

As the networks proliferate all over the world and the application of the geographical information increase recently, the importance of effective access and exchange of GIS data is recognized. However, existing GIS data are generated by many different organizations without proper standard methodologies and data exchange facilities such as clearing houses are being operated on different DBMS with their own schemata. It makes difficult for users to access and utilize the GIS data even the data are open to public. In this research, we provide the users a search system that interfaces heterogeneous repository systems. In order to interact heterogeneous DBMS we utilize the metadata interchange standard (XMI) from OMG.
