摘　　要：对具有代表性的异构数字仓储互操作相关项目进行简要介绍,结合已有仓储互操作项目经验和OAI-ORE规范,提出基于OAI-ORE的异构数字仓储互操作框架。该框架的核心是使用OAI-ORE抽象数字对象模型对异构仓储不同数据模型进行统一表达,并在其基础上通过设置互操作层的Harvest、Obtain和Put标准服务接口,屏蔽仓储之间的异构性,实现异构仓储复合数字对象获取和存入方法的统一。The paper introduces several representative projects about heterogeneous digital repository interoperation. Combining the OAI - ORE specification and experiences obtained from existing projects, the author proposes the interoperation framework of heterogeneous digital repository based on OAI - ORE. The core of the framework is unifying heterogeneous data models of different kinds of repository by OAI - ORE abstract object model. It also sets up cross - repository interoperability layer with harvest, obtain and put standard service interface to mask the differences among repositories. Using this layer, the access and storage method of compound digital objects can be unified in different repositories.
