摘要
[目的/意义]当前数字图书馆系统数字资源可信性、互操作性及可扩展性等成为阻碍数字图书馆发展的主要问题。[方法/过程]基于区块链技术提出一种新型分层数字图书馆体系架构,并详细介绍各层的关键功能组件和核心服务模块,最后与已有相关数字图书馆体系架构进行综合比较。[结果/结论]理论分析表明,所提架构利用区块链技术的分布式账本结构、安全可靠、透明可信、时序不可篡改等特征能有效解决数字图书馆数字资源可信性,增强系统架构的互操作性及可扩展性,实现异构数字资源的安全流通。
[Purpose/significance]At present,the digital resource problems of trust,interoperability and scalability in digital library system have become the major obstacle for the development of digital library.[Method/process]Based on the blockchain technology,we proposed a novel hierarchical digital library system architecture.Then,we described the key functional components and core service modules of each layer in detail.Finally,we compared our proposed digital library system architecture with the others.[Result/conclusion]Theoretical analysis proves that our proposed digital library system architecture exploits the features of bloekchain,such as distributed ledger architecture,security and reliable, transparent and credible,time-series and tamper-resistant,can solve the trust problem of digital resource,enhance the interoperability and sealability and achieve the security flow of heterogeneous digital resource.
