Many countries have applied new digital technology to preserve precious culture or historical relics. However, most institutions still use their own work flows for digital archives implementation. This paper analyzes and compares several international organizations of active digital archives projects with the technology, specifications and metadata including OAIS (Open Archival Information System) and NISO (National Information Standards Organization) reference models. We propose an executive approach for digital archives construction principles that contain the practical work flows, operation methods, and specifications. Moreover, we create the use of UML (Unified Modeling Language) for easy understanding of analysis and implementation on digital archives domains. In addition, this paper illustrates and evaluates the practicability according to the experience of the Hwa-Kang Museum.
