摘要
传统元数据存储方法受到非活跃元数据影响,存储耗费时间长,读写结果不精准,导致元数据存储效果不佳。为了解决该问题,提出了面向电子数字文献保存的元数据存储系统设计。为了方便系统调试,设计FPGA主控单元,对SRAM缓存管理模块中的缓存输入信号进行缓存。设计保存于电子数字文献中的元数据读写流程,利用元数据分级算法,区分活动和非活动元数据,缩短数据存储时间,通过数据总线将命令写入存储器,完成元数据的存储。由实验结果可知,该系统最短存储时间为7 s,读写结果与实际内容较为一致,说明其具有良好的存储效果。
The traditional metadata storage method is affected by inactive metadata,the storage takes a long time,and the result of reading and writing is not accurate,resulting in poor metadata storage effect.In order to solve this problem,a metadata storage system design for electronic digital document preservation is proposed.In order to facilitate system debugging,the FPGA main control unit is designed to buffer the buffer input signal in the SRAM buffer management module.Design the metadata read and write process stored in electronic digital documents,use metadata classification algorithm to distinguish active and inactive metadata,shorten the data storage time,and write commands into the memory through the data bus to complete the metadata storage.It can be seen from the experimental results that the shortest storage time of the system is 7 s,and the read and write results are more consistent with the actual content,indicating that it has a good storage effect.
