The data-intensive computing generates a huge number of data in wide area network. The DataGrid technology tries to manage such distributed data on the Internet to provide the quick and efficient data search/access mechanism. The difficulties of the data access on DataGrid systems is caused from the differences in the data management manner and policy among organizations which manage storage resources. In this paper, we propose the new distributed data management scheme and design for data-intensive computing. Especially, we focus on the data attributes. We define the pairs of data attribute and its values as its metadata. In our system, users can be find/access data with the metadata. We have been developing the prototype systems. We show the usage of our system with the applications.
