Implementing citation management and report generation value-added services over OAI-PMH compliant repositories

The National Documentation Center (EKT) has developed HELIOS (http://helios-eie.ekt.gr) - the institutional repository of the National Hellenic Research Foundation (NHRF) aiming at collecting the scientific work of its associate researchers. DSpace has been used as the repository platform in the implementation of HELIOS. According to the repository literature (A DRIVER’s Guide to European Repositories, Amsterdam University Press, 2008), offering value-added services to researchers can be an important factor for repository take-up, able to significantly increase deposits through self-archiving. Therefore, in order to encourage the usage of HELIOS among the NHRF researchers, an application providing value-added services over the repository has been developed. In brief, this application harvests the digital repository's data and presents them outside the repository's framework, enabling citation management and configurable custom reporting, for example producing publication lists per researcher and institute, exactly in the format applied in the institute annual report. The application is in operation on top of the HELIOS DSpace-based repository; however it has been designed and implemented to depend only on information retrieved via OAI-PMH, so that it can work with any OAI-PMH compliant repository platform (DSpace, Eprints, Fedora, etc.

A funder repository of heterogeneous grey literature material with advanced user interface and presentation features

The present contribution concerns the development of a funder repository aiming at the dissemination, reuse and preservation of mainly grey literature material of diverse types. This material which was produced under the auspices of large scale (multi-billion Euros) funding programmes of the Hellenic Ministry of Education (co-financed by the European Union). The project involved the handling of a wide range of content, like (among others) studies, reports, educational material, videos, theses, material from a range of conferences/events. The project has been successfully completed and the system is publicly available since spring 2011 at http://repository.edulll.gr. In this repository creation use case, technical enhancements were used to provide the means to organise, process and import to the repository a wide range of heterogeneous material. Special facilities for the support of these workflows were included. The metadata schema used is an application profile using elements for Qualified Dublin core, LOM and PREMIS. A major part of the work concerned mechanisms to enhance presentation of the digital material and better navigation to the corresponding metadata records. Easy browsing to the wide range of the available content was achieved using a tag cloud feature that was developed from scratch for the purposed of the project. The tag cloud was applied to the thematic category data field, which used the EuroVoc thesaurus as a controlled vocabulary for assigning thematic categories to individual items. Regarding digital material presentation, a streaming video player was incorporated into the item pages to enable easy access to the video content and including configuration capabilities that enabled differentiation of the player presentation based on values of specific metadata fields. Regarding text documents, an online reading feature was included in the repository, enabling users to open, read online and search into big texts without the need to save them in their systems - an implementation fully compatible with tablets like iPad and Android-based devices. The infrastructure that enables that is based on transforming documents to JPEG2000 images, including OCR text for searching, and serving them to users via an extended version of the Internet Archive Book reader using open source and W3C standards compatible technologies.Includes: Conference preprint, Powerpoint presentation, Abstract and Biographical notesXAInternationa
