为构建一个分布式、集成化的数据环境,实现信息共享的个人信息空间管理系统,提出了基于Web服务资源框架的个人信息空间管理系统模型。针对个人信息更新快、个人计算环境变化相对频繁等特点,研究了通过不同设备间的数据同步保证个人信息视图的一致性,以及通过订阅/发布机制来支持不同用户对同一数据的共享访问。通过系统性能测试的结果表明了该模型的可行性和有效性。
To construct the personal space of information management system that can share the information and has a distributed and integrated data environment,a personal space of information management system based on WSRF is put forward.In this system,aimed to the characteristic of personal information renovates rapidly,and considering the personal environment,two methods are proposed to resolve the consistency of data.One method is the synchronization of data among equipments.The other method uses the publish/subscription mechanism to solve the sharing of data among different users.Finally,the feasibility and validity of the system is validated by test performance.
