Abstract: Seamless migration of application for individual users is one characteristic of the pervasive environment.The existing work in this area is mostly regard for the particular application，which is difficult to meet the actual demand.In this paper，a universal resource description framework-ARDF（Application Resource Description Framework） is proposed.This framework can be used to organize and describe the state of resource for an application，so as to support the access and rebuild of the state of application in migration.Based on this framework，a system is implemented to migration the application of OFFICE in the smart space-FollowMe.

Key words: application migration, resource state, resource description framework

摘要： 针对个人用户的应用无缝迁移是普适环境特征之一。此方面现有的工作大多表现为针对某个特定应用的迁移能力，较难满足实际需求。给出了一个具有一定普遍意义的应用资源描述框架，该框架可用于描述与应用相关的系统和用户资源的状态，从而支持需迁移的应用状态的获取和重建。在此基础上，在自行设计和实现的FollowMe普适空间中，实现了一个针对个人Office办公需求的应用迁移示范应用。
