OAI-Publishers are software modules implementing the OAI-PMH protocol interface, enabling harvesting of metadata records describing the digital resources of a Digital Repository. Typically, such modules are manually configured and implemented to export records contained into a local store according to the metadata formats supported by the relative Repository. Due to their static nature, these a...

Viewshare is a free, Library-of-Congress-sponsored platform that empowers historians, librarians, archivists and curators to create and customize dynamic interfaces to collections of digital content. This demonstration of Viewshare will start with an example spreadsheet or data harvested via OAI-PMH to generate distinct interactive visual interfaces (including maps, timelines, and sophisticated...

In this paper, we discussed the problems brought by the schema heterogeneity in DLs, especially those problems found in the application of the OAI-PMH protocol. This paper studies the problem from two perspectives, namely the schema and the architecture respectively. A preliminary architecture is provided that integrates the ontology, agent, P2P together to support the schema mapping. And the s...

This paper describes the development of a testbed for formalized categories of collection-item metadata relationships. Because these categories are characterized using logic-based formal languages and are most naturally analyzed by exploring inferences and logical relationships, the testbed is based on contemporary semantic web architecture. We describe the design and development of the testbed...

the paper provides an overview over the functionalities of the proposed harvesting model (bura – burdwan university research archive) and describes the activities involved in harvesting resources from oai compliant lis (library and information science) repositories. repositories, registered in  opendoar database, containing 'library and information science' as one of the key subject have been c...

Numerous papers have addressed building Union Catalog (UC) technologies, such as metadata schema, data exchange (e.g., OAI-PMH, Z39.50), and resource classification. In contrast to these approaches, in this article, we focus on UC technologies that leverage resource utilization across digital resources. We take the repositories of National Digital Archives Program (NDAP) in Taiwan as the projec...

In the World Wide Web, a very large number of resources are made available through digital libraries. The existence of many individual digital libraries, maintained by different organizations, brings challenges to the discoverability and usage of these resources by potential users. A widely-used approach is metadata aggregation, where a central organization takes the role of facilitating the di...

By the end of the late 90’s the Open Archives Initiative needed direction to insure its improvement and thus, created the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) standard. The movement showed a rise in popularity, followed by a decline then a relative stabilization. This process was essentially a way to ensure the viability of open archive repositories. However, a me...
