Research on the interoperability architecture of the digital library Grid

With the rapid development of the digital libraries, Interoperability is the problem to realize the real information sharing and eliminate the digital information islands. In this paper, the character and requirement of digital library interoperability is discussed. As the limitations of the current technologies in the realization of the large-scale digital library interoperability on the Web, the architecture of the digital library interoperability is put forward based on the Grid technology, and the working process of the digital library Grid is presented. Using the Grid technologies, the high performance OAI federated search service is realized.
