During the past decade we have seen a remarkable expansion of Internet which connects millions of users at academic, industrial, and government institutions nation-wide and world-wide. Additionally, it has caused a rapid growth in the available amount of information and the variety of forms it is represented in. Numerous Internet resource discovery systems have come into existence to solve the problem. The interoperability of these various systems and the efficiency of their serving as components of an integrated digital library system remain to be improved. We have proposed a three-layer interoperability architecture which alleviates this problem. It allows a large, distributed user base, autonomies of local systems, ease in integration of heterogeneous systems, and efficient retrieval of information. The implementation issues of our architecture have been investigated and we believe that it is feasible and effective.
Keywords: Interoperability, resource discovery systems, digital libraries.
