The actions are usually trivial, implicit yet significant for the protection of collection during the wartime. Records of those actions, events, and particularly, the related persons, organizations may be scattered but deserve further attention since the records are precious to human knowledge protection efforts. Searching, identifying and collecting the related resources from the scattered data sets is not as complicated as developing an ontology for this domain of collection protection during the wartime period. This study has selected 1939-41, in the Second Sino-Japanese War during WWII when there were figures working on the collection protection projects that have been documented in the historical archives and many other resources, including oral history, journals, digital documentation, conference papers, literature reviews, etc. The preliminary ontology models for the protection of wartime period collection have been developed based on one of the oral history. The current research has further tuned and finalized the ontology of collection protection during the wartime period by analyzing the multi-sets of data resources. The implications of the research results are two folds: firstly, it could shed lights on the classification system for a digital library of this domain, and secondly, it could benefit the historical researchers for providing new clues in this line of collection protection during the wartime period research.
