[Objective] Integrate open source file-format identification tool into Digital Preservation System (DPS) to get complex object format information. [Context] Based on the existing open source tools, to meet the practical requirements, the DPS needs choose appropriate tools for application integration. [Methods] Analyze and compare several open source file-format identification tools. According to the practical requirements, DROID has been chosen for the DPS. At the same time to meet the efficiency requirements of DPS, an idea of choosing DROID batch format identification of complex objects is proposed. [Results] Batch format processing module which is integrated with DROID is utilized to complete format identification of complex objects and technical metadata extraction. [Conclusions] DROID is an excellent open source tool, of which the automatic batch processing can meet the requirements of DPS.
