Abstract 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.
