摘　　要：随着对智慧型博物馆的建设,各种文物藏品信息不断地丰富,形成的海量多媒体数据信息也越来越多,这对文物数据存储管理系统提出了更高要求.针对数字博物馆中海量多媒体下多维元小文件资源的特点,基于Hadoop File System(HDFS)分布式文件系统,将大量小文件合并成大文件,并对元数据的读写过程进行优化;根据不同海量小文件存储策略,从打包小文件、减少文件个数、集中缓存管理等方面优化存储效果.With the construction of the smart museum, various heritage collection information is increasing constantly, and more and more multimedia data information is formed. That demands a better system of heritage data storage and management. In view of the characteristics of small file resource in the massive multimedia data in the digital museum, based on the Hadoop File System （ HDFS ） distributed file system, a large number of small files are merged into big files, and the metadata reading and writing process are optimized. According to the strategy of storing mass different small files, the storage results should be optimized from the aspects of packing small files, reducing the number of files and centralizing cache management.
