The National Archives of Korea (NAK) has adopted a migration strategy to convert preservation formats to ensure the long-term accessibility and reproducibility of digital records. To select an appropriate preservation format, it is necessary to conduct evaluations based on the preservation format selection system. Evaluating file formats is challenging due to limited access to reliable information about file formats and the requirement for specialized knowledge of their technical specifications and characteristics. As a result, the evaluation process can act as a barrier to the practical implementation of the preservation format selection system. This study aims to improve the efficiency of preservation format selection evaluations by proposing the functionality of a support tool divided into two domains: information management and evaluation support. Furthermore, to assess the feasibility of this tool, the study analyzed the information provided by three reliable file format information portals and compared it with the evaluation criteria (common) of the preservation format selection system to examine the potential for information integration.
