Many institutions grant access to their metadata repositories via the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). However, this protocol has two significant drawbacks: it does not make its resources accessible via dereferencable URIs, and it provides only restricted means of selective access to metadata. The OAI2LOD Server handles these shortcomings by republishing meta...

We describe mod_oai, an Apache 2.0 module that implements the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). OAI-PMH is the de facto standard for metadata exchange in digital libraries and allows repositories to expose their contents in a structured, application-neutral format with semantics optimized for accurate incremental harvesting. mod_oai differs from other OAIPMH i...

We present the architectural decisions involved in adding an Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) interface to the NASA Langley Research Center Atmospheric Science Data Center (ASDC). We review four possible implementation strategies and discuss the implications of our choice. The ASDC differs from most OAI-PMH implementations because of its complex data model, la...

mber of on-line journals and scientific l libraries (DL) exist today, however, is a lack of interoperability between these ies. Researchers have been looking at this and one of the major efforts to address ical interoperability among distributed es is the Open Archives Initiative (OAI). bjective of OAI is to develop a lowr, lightweight framework to facilitate the very of content in distributed ...

Im Projekt FIS-I, das vom Bundesministerium für Bildung und Forschung (BMBF) gefördert wird, soll der Zugriff auf Informatik-Literatur zentralisiert werden. Die Projektpartner Universtät Karlsruhe (Collection of Computer Science Bibliographies) und TU München(LEABiB) stellen hierfür die bibliographischen Daten bereit. In diesem Beitrag werden die praktischen Erfahrungen vorgestellt, die bei der...

Purpose – To examine the relationship between deposit of electronic theses in institutional and archival repositories. Specifically the paper considers the automated export of theses for deposit in the archival repository in continuation of the existing arrangement in Wales for paper-based theses. Design/methodology/approach – The paper presents a description of software that makes use of the O...

This paper focuses on the multifaceted use of the OAI-PMH in a repository architecture designed to store digital assets at the Research Library of the Los Alamos National Laboratory (LANL), and to make the stored assets available in a uniform way to various downstream applications. In the architecture, the MPEG-21 Digital Item Declaration Language is used as the XML-based format to represent co...

The Open Archives Initiative (OAI) was created as a practical way to promote interoperability between eprint repositories. Although the scope of the OAI has been broadened, eprint repositories still represent a significant fraction of OAI data providers. In this article I present a brief survey of OAI eprint repositories, and of services using metadata harvested from eprint repositories using t...

The paper deals with the necessity of systemic solution for metadata providing by local archives into central repositories and its subsequent implementatiton by the Department of Information Technologies, Faculty of Economics and Management, Czech University of Life Sciences in Prague, for the needs of the agrarian WWW AGRIS portal. The system supports the OAI-PMH (Open Archive Initiative – Pro...
