The National Assembly Archives of the Republic of Korea has been using the National Assembly Archives and Records Management System, which added some archival function to the Standard Records Management System that they had previously developed. However, the Standard Records Management System has limits in order to reflect all the business functions of the National Assembly Archives, which also acts as an archival institution, because the system had been developed and distributed to perform the function of a records center. Moreover, the current National Assembly Archives and Records Management System focuses on the management of official records transferred in accordance with the regulations. For this reason, it is difficult to register and manage various record types such as records of the members of the National Assembly (related to legislative activities), oral history collected from the National Assembly leader, audiovisual records of proceedings, and so on. As such, this study analyzed the problems of the current National Assembly Archives and Records Management System and conducted case studies of the systems in the National Archives, the Presidential Archives, Changwon City, and the Cultural Heritage Administration. Through this research, it proposed that system functions, metadata, the target system of the National Assembly Archives, and the Records Integrated Management System need a development plan.
