OPUS is an open-source software package under the GNU General Public License used for creating Open Access repositories that are compliant with the Open Archives Initiative Protocol for Metadata Harvesting. It provides tools for creating collections of digital resources, as well as for their storage and dissemination. It is usually used at universities, libraries and research institutes as a platform for institutional repositories.

History

OPUS, originally an acronym for the Online Publikationsverbund der Universität Stuttgart, was developed with the support of the Deutsches Forschungsnetz (DFN) in 1997 and 1998 at the University of Stuttgart Library. OPUS is used at many universities and library networks. [2] The Library Service Centre for Baden-Württemberg  [ Wikidata ] (BSZ) took over development from University of Stuttgart Library, however, since December 2010, the Cooperative Library Network of Berlin-Brandenburg  [ Wikidata ] (KOBV) has taken over the development and management of the project at the Zuse Institute Berlin (ZIB).

In Germany, the OPUS software is the most commonly used for the operation of open access repositories (according to a survey carried out in 2012, [3] 77 repositories were based on OPUS). OPUS-based repositories may either be hosted and operated by universities on their own, or as part of hosting services provided by the German library network. The KOBV provides hosting for more than 35 instances of OPUS. [4] Apart from Germany, OPUS is also used in Serbia by two research institutes. [5]

Development

The current version, OPUS 4, is being developed by the Cooperative Library Network Berlin-Brandenburg (KOBV) at the Zuse Institute Berlin (ZIB). The earlier development was coordinated by the Library Service Centre for Baden-Württemberg (BSZ) and the Stuttgart University Library.

Major partners have included the Saxon State and University Library Dresden (SLUB), Bielefeld University Library, Saarland University and State Library Saarbrücken (SULB), University Library of the Hamburg University of Technology (TUHH), Cooperative Library Network Berlin-Brandenburg (KOBV) and University Library Centre of North Rhine-Westphalia (HBZ).

Technology

OPUS 3.x was written in PHP 4. The current version, OPUS 4, is developed in PHP (version 5.3) and is based on the Zend Framework and the search engine Solr. Data are stored in a MySQL database. Both versions are designed for LAMP environments.

<span class="mw-page-title-main">Open Archives Initiative</span>

The Open Archives Initiative (OAI) was an informal organization, in the circle around the colleagues Herbert Van de Sompel, Carl Lagoze, Michael L. Nelson and Simeon Warner, to develop and apply technical interoperability standards for archives to share catalogue information (metadata). The group got together in the late late 1990s and was active for around twenty years. OAI coordinated in particular three specification activities: OAI-PMH, OAI-ORE and ResourceSync. All along the group worked towards building a "low-barrier interoperability framework" for archives containing digital content to allow people harvest metadata. Such sets of metadata are since then harvested to provide "value-added services", often by combining different data sets.

CiteSeerX is a public search engine and digital library for scientific and academic papers, primarily in the fields of computer and information science.

The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a protocol developed for harvesting metadata descriptions of records in an archive so that services can be built using metadata from many archives. An implementation of OAI-PMH must support representing metadata in Dublin Core, but may also support additional representations.

An institutional repository is an archive for collecting, preserving, and disseminating digital copies of the intellectual output of an institution, particularly a research institution. Academics also utilize their IRs for archiving published works to increase their visibility and collaboration with other academics However, most of these outputs produced by universities are not effectively accessed and shared by researchers and other stakeholders As a result Academics should be involved in the implementation and development of an IR project so that they can learn the benefits and purpose of building an IR.

<span class="mw-page-title-main">Fedora Commons</span>

Fedora is a digital asset management (DAM) content repository architecture upon which institutional repositories, digital archives, and digital library systems might be built. Fedora is the underlying architecture for a digital repository, and is not a complete management, indexing, discovery, and delivery application. It is a modular architecture built on the principle that interoperability and extensibility are best achieved by the integration of data, interfaces, and mechanisms as clearly defined modules.

An Open Archival Information System is an archive, consisting of an organization of people and systems, that has accepted the responsibility to preserve information and make it available for a Designated Community. The OAIS model can be applied to various archives, e.g., open access, closed, restricted, “dark”, or proprietary.

ScientificCommons was a project of the University of St. Gallen Institute for Media and Communications Management. The major aim of the project was to develop the world’s largest archive of scientific knowledge with fulltexts freely accessible to the public. The project was closed down in 2014.

BASE is a multi-disciplinary search engine to scholarly internet resources, created by Bielefeld University Library in Bielefeld, Germany. It is based on free and open-source software such as Apache Solr and VuFind. It harvests OAI metadata from institutional repositories and other academic digital libraries that implement the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), and then normalizes and indexes the data for searching. In addition to OAI metadata, the library indexes selected web sites and local data collections, all of which can be searched via a single search interface.

An open repository or open-access repository is a digital platform that holds research output and provides free, immediate and permanent access to research results for anyone to use, download and distribute. To facilitate open access such repositories must be interoperable according to the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). Search engines harvest the content of open access repositories, constructing a database of worldwide, free of charge available research.
