| Summary: | 碩士 === 國立暨南國際大學 === 資訊工程學系 === 94 === With the explosive growth of the Web, integrating various resources from diverse information systems is becoming an increasingly important task, especially for integrating digital archives into digital libraries. Organizations make efforts to digitize archives and carry out information systems to manage these archives and publish them on the Web. Archives managed by various information systems are hard to be seamlessly exchanged. Consequently, the interoperability problem becomes a significant issue of resource integration in digital libraries. The Open Archives Initiative–Protocol for Metadata Harvesting (OAI-PMH) is proposed to facilitate metadata sharing based on the Web. With the growing acceptance of the OAI framework, many information systems support OAI-compliant services. In this paper, we implement the OAI system as a framework to integrate heterogeneous resources. The system is also integrated with portal and search systems to provide union catalog and search services. Based on the common metadata, Dublin Core, various resources like HTML, XML, files system and databases can be integrated into a single portal through our OAI system. We also consider the synchronization issue not involved in the OAI-PMH. Based on these criteria, we implement an OAI-based portal system to integrate heterogeneous resources from diverse systems. We also extend the OAI-PMH for improving drawbacks that data cannot be synchronized through the OAI framework. The enhancement is also compatible with other OAI-compliant systems.
