In the past several years, the aboriginal knowledge organization structure has received a respectable amount of attention. However, aboriginal knowledge is commonly spread by oral tradition and rarely through writing. With regards to such behavior, it is understandable that the aboriginal knowledge organization structure is incomplete. Currently, the classification of Taiwan's aboriginal knowledge in the New Classification Scheme for Chinese Libraries is still roughly sorted with descriptions of aborigines classified simply by tribe while other subject matters and aspects relating to the indigenous people are scattered under the classification number of relevant subjects. It is clear that applying this type of classification on aboriginal documents and records has quite a number of inadequacies. Responding to contemporary trends in information management and to the needs of Taiwan's Indigenous Peoples Resource Center, this research aims to detail Taiwan's aboriginal knowledge organization structure starting with the upper-level structure, and through the integrated and interactive participation of aboriginal scholars, anthropologists, and professionals in library and information sciences., the core of the upper-level structure is established and confirmed. In this way, further work division and collaboration is possible, and aboriginal knowledge with different themes and facets can be classified by experts of different fields. This research hopes to provide Taiwan's Indigenous Peoples Resource Center with a classification system that can correspond more to the indigenous people's point of view and also serve as future reference for the Center.
