标注是个人数据空间中对非结构化数据进行管理与维护的重要手段。标注技术如何与网络环境中个人信息管理模型有机结合，是数据管理与共享的前提。本文提出一种分布式个人信息管理系统架构，支持网络环境中个人数据空间的内容管理及共享；在此基础上，定义了个人信息标注的数据模型与操作模型，支持数据项粒度的多种管理服务，并通过原型系统的实现验证了上述研究中的关键技术。

Tagging is one of the most important means regarding to the management and maintenance of the semistructured or unstructured data within the personal dataspace. However, in the presence of the networking environment, how to incorporate the tagging technique with the personal information management model can be tricky and the prerequisite of data management and sharing. In this paper, a distributed personal information management architecture supporting the content management of sharing is proposed. The data model and the operational service model are also discussed to support various management services at the granularity of the personal information item. A prototyping system is developed for the preliminary validation purpose.
