In this paper, we propose a metadata exchange interface for interdisciplinary contents-sharing. The interface is obtained by introducing the research results of a specific sociological study. We have developed a Contents Management (CM) System on intra-university network to test the feasibility of our interface. The main feature of our system is its function of focusing searches in Web documents. Our interface module converts tag-labels into items of 5W1H. By conducting an experimental use of our system, we confirmed that the module on it is very important for contents sharing across various disciplines.
