The study reports a preliminary analysis for the No-Gun Ri massacre documentation strategy based on Hackman and Wornow-Blewett’s implementation model, as an appraisal and selection method for No-Gun Ri Digital Archives. It intends to review the theoretical background for this process, inlcuding a history of the No-Gun Ri massacre and the development of documentation strategy. From the theoretical analysis, this study identified the No Gun Ri documentation strategy processes in 5 categories: “cooperative collecting”, “collecting in specific areas”, “identifing missing areas” and “advisory group”. With these 5 categories, this study discusses the application of the Hackman and Wornow-Blewett’s implementation model in the No Gun Ri case and reviews the strategy’s pros and cons. As a result, firstly, we classfy focusing groups into “victims and bereaved family”, “government”, “civil society”, “the press” and “literature and art”. Secondly, we also classify documentation categories into “massacre records”, “investigation activity records” and “cherish memory”.
