摘要
Ancient Chinese architecture was digitalized preserved in the projects funded by the government in the past few years. Many application systems have been built in order to use these digital resources effectively. In this paper, we investigate a practical framework for data exchange and sharing among heterogeneous databases of these systems. An XML-based metadata is proposed as a standard for data representation and exchange. And a data exchange model is presented. An application system using the proposed model has been developed. It has been proved that the model works well.
