Abstract
Many universities and other research organizations have proceeded construction of academic resource repositories under the leadership of National Institute of Informatics (NII). Because it requires much labor to create metadata contents of academic resources, development of tools or services enabling to easily create metadata contents is expected. This paper proposes a system which converts BIBTEXmetadata of academic resources - widely used by researchers in science and engineering - into NII metadata format in order to support constructions of academic resource repositories. The proposed system enables to reduce almost four-fifth of workloads of creating metadata contents. In addition, utilizing compiler compiler to develop the proposed system reduced the develop cost.
