COAR Roadmap Future Directions for Repository Interoperability

« In the past few years, Open Access repositories and their associated services have become an important component of the global e-research infrastructure. Increasingly, repositories are also being integrated with other systems, such as research administrative systems and with research data repositories, with the aim of providing a more integrated and seamless suite of services to various communities. Repositories can also be connected into networks (e.g. at the national or regional level) to support unified access to an open, aggregated collection of scholarship and related materials that machines can mine enabling researchers to work with content in new ways and allowing funders and institutions to track research outputs.
Scholarly communication is undergoing fundamental changes, in particular with new requirements for open access to research outputs, new forms of peer-review, and alternative methods for measuring impact. In parallel, technical developments, especially in communication and interface technologies facilitate bi-directional data exchange across related applications and systems. The aim of this roadmap is to identify important trends and their associated action points in order for the repository community to determine priorities for further investments in interoperability. »

Enriching the local catalog with bibliographic data exposed online: interaction with the national catalog via web services

« Interoperability efforts represent a significant part within the fieldwork of documentary engineering. The enhancement of its catalog is one of its primary objectives. From that preoccupation came the idea of using a web service of the ABES in order to offer a functionality such as “Get more information about this author” accessible from a view on the authority record, usable during the consultation of the OPAC. This web service brings back directly pieces of information coming from IdRef, the authority database reference of the SUDOC and displays the abbreviated forms of the different records linked to a given authority, classified by relator code. The response in XML or in JSON is elaborated in order to be in compliance with the graphic charter of the ILS and to not create any disruption through the chain of information. A general problematic assumption shows the high stakes and the context in which this web service was imagined and designed. A global expertise of the general outline of the ABES network is useful when trying to understand this functionality; the collaborative structure is briefly described. The articulation between the local and the national bases is made possible with the mediation of a PHP script whose major steps are detailed. Finally, as this project is aimed at being an experiment to reach further and operate other interactions of this kind, it is also important to apprehend the perspectives for the future that such new methods of accessing information can open. The implementation of this functionality has contributed to explore and stabilize new methods of project developments, but also to question the opening of the catalog on the universe of knowledge and to its potential use as a discovery tool. It questions again the interdependence between the local catalog and the SUDOC and has the virtue to set the issues according to a user-centered design. »

Towards an Interoperable Digital Scholarly Edition

« Recent proposals for creating digital scholarly editions (DSEs) through the crowdsourcing of transcriptions and collaborative scholarship, for the establishment of national repositories of digital humanities data, and for the referencing, sharing, and storage of DSEs, have underlined the need for greater data interoperability. The TEI Guidelines have tried to establish standards for encoding transcriptions since 1988. However, because the choice of tags is guided by human interpretation, TEI-XML encoded files are in general not interoperable. One way to fix this problem may be to break down the current all-in-one approach to encoding so that DSEs can be specified instead by a bundle of separate resources that together offer greater interoperability: plain text versions, markup, annotations, and metadata. This would facilitate not only the development of more general software for handling DSEs, but also enable existing programs that already handle these kinds of data to function more efficiently. »

Data Curation in the OpenAIRE Scholarly Communication Infrastructure…

Data Curation in the OpenAIRE Scholarly Communication Infrastructure :

« OpenAIRE is the European Union initiative for an Open Access Infrastructure for Research in support of open scholarly communication and access to the research output of European funded projects and open access content from a network of institutional and disciplinary repositories. This article outlines the curation activities conducted in the OpenAIRE infrastructure, which employs a multi-level, multi-targeted approach: the publication and implementation of interoperability guidelines to assist in the local data curation processes, the data curation due to the integration of heterogeneous sources supporting different types of data, the inference of links to accomplish the publication research contextualization and data enrichment, and the end-user metadata curation that allows users to edit the attributes and provide links among the entities. »


SW MIS A Semantic Web Based Model for…

SW-MIS: A Semantic Web Based Model for Integration of Institutional Repositories Metadata Records :

« Despite providing a low level of interoperability, the method of Metadata Harvesting is very common within service providers for unifying access to the institutional repositories. On the other hand, the semantic web-based method of Object Reuse and Exchange (ORE) has not been widely adopted by service providers due to its complexity as well as the small number of ORE compatible archives. The purpose of this study is to provide a new metadata integration model, through which resources harvested from repositories are aggregated and converted to Resource Description Format (RDF) so that can take advantage of integrating into the semantic web resources. For the purpose of this study a metadata integration model, namely SW-MIS (Semantic Web-based Metadata Integration System) has been developed, which involves four steps, including: metadata harvesting, exposing harvested metadata, creating Semantic Web compliance data sets, and providing the search and brows interface. For each step, a specific software tool was developed, so that together formed an information workflow system. »


The Current State of Open Access Repository Interoperability…

The Current State of Open Access Repository Interoperability (2012) :

« In the past few years, Open Access repositories and their associated services have become an increasingly important component of the global e-Research infrastructure. The real value of repositories is their potential to be connected in order to develop a network of repositories which enables unified access to an open, aggregated mass of scholarship and related materials that machines and researchers can work with in new ways.

However, this potential to create a unified body of scholarly materials is entirely reliant on interoperability – specifically, that repositories follow consistent guidelines, protocols, and standards for interoperability which allow them to communicate with each other; connect with other systems; and transfer information, metadata, and digital objects between each other. The repository infrastructure is still relatively new, leading to an evolving interoperability landscape that at first sight may appear chaotic, confusing, and complex.

This report is designed to be the first stage of a multi-phase process aiming to establish the COAR Roadmap for Interoperability. The second phase is planned to be completed with the release of a follow-up report: Future Directions for Interoperability. The follow-up report will address emerging issues and current research & development efforts. »


Federated Search Service for OAI-compliant, Open-Access Repositories in India

Many of the research institutions and universities across the world are facilitating open-access (OA) to their intellectual outputs through their respective OA institutional repositories (IRs) or through the centralized subject-based repositories. The registry of open access repositories (ROAR) lists more than 2850 such repositories across the world. The awareness about the benefits of OA to scholarly literature and OA publishing is picking up in India, too. As per the ROAR statistics, to date, there are more than 90 OA repositories in the country. India is doing particularly well in publishing open-access journals (OAJ). As per the directory of open-access journals (DOAJ), to date, India with 390 OAJs, is ranked 5th in the world in terms of numbers of OAJs being published.

Much of the research done in India is reported in the journals published from India. These journals have limited readership and many of them are not being indexed by Web of Science, Scopus or other leading international abstracting and indexing databases. Consequently, research done in the country gets hidden not only from the fellow countrymen, but also from the international community. This situation can be easily overcome if all the researchers facilitate OA to their publications.

One of the easiest ways to facilitate OA to scientific literature is through the institutional repositories. If every research institution and university in India set up an open-access IR and ensure that copies of the final accepted versions of all the research publications are uploaded in the IRs, then the research done in India will get far better visibility. The federation of metadata from all the distributed, interoperable OA repositories in the country will serve as a window to the research done across the country.

Federation of metadata from the distributed OAI-compliant repositories can be easily achieved by setting up harvesting software like the PKP Harvester. In this paper, we share our experience in setting up a prototype metadata harvesting service using the PKP harvesting software for the OAI-compliant repositories in India.
