    Towards a harmonization of metadata application profiles for agricultural learning repositories 2008
    Also available in:
    No results found.

    Metadata interoperability allows the exchange and preservation of crucial learning and teaching information, as well as its future reuse among a large number of different systems and repositories. This paper introduces work around metadata interoperability that has taken place in the context of the Agricultural Learning Repositories Task Force (AgLR-TF), an international community of the stakeholders that are involved in agricultural learning repositories. It particularly focuses on a review and assessment of metadata application profiles that are currently implemented in agricultural learning repositories. The results of this study can be found useful by who are designing, implementing and operating agricultural learning repositories, facilitating thus metadata interoperability in this application field.

    Results from a study of the implementation of metadata application profiles in Agricultural Learning Repositories 2008
    Also available in:

    In technology-enhanced learning, metadata interoperability has been identified as an important issue. It allows not only the exchange and preservation of crucial learning and teaching information (such as competency profiles, learning activities, and descriptions of learning resources), but also its future re-use among a large number of different systems and repositories. In the field of agricultural education and training, learning technologies’ specifications and standards have not yet b een widely adopted. Few initiatives have reported implementing them, and in most cases only to describe learning resources by using IEEE Learning Object Metadata (LOM), Dublin Core (DC) or a combination of the two. This results in introduction of dispersed efforts and systems with significant differences between them. In this paper, we present results of a study aiming at the review and assessment of implementations of metadata standards in agricultural learning repositories. More specif ically, it assesses the current status of development and implementation of metadata application profiles based on standards such as IEEE LOM and DC.

    Scielo articles available to the agricultural community using OAI-PMH in AGRIS AP XML Format 2008
    Also available in:
    No results found.

    This article reports a new way of getting access to SciELO full text journal articles using AGRIS AP XML format to harvest SciELO metadata and to include them into the AGRIS repository. It covers the following main steps of the work carried out: • Selecting about 43 journals with agricultural thematic from the Web site of SciELO; • Defining the methodology for harvesting; • Harvesting legacy data and then doing incremental harvesting for the new data from the selected SciELO journal articles for inclusion in the AGRIS XML repository; • Inclusion of SciELO articles and open access to them through the AGRIS search portal at http://www.fao.org/agris/search/search.do?query=%2Bcenter%3A%28XS%29 • Testing and proposals for improvement and future use of this feature. We share the methodology used, problems encountered, and the expected benefit. This work proves that semantically rich metadata for agricultural science and research publications based on the “AGRIS Applic ation Profile” from the SciELO repository can be handled by the OAI-PMH protocol. It shows how the selected subset of metadata created with an ISIS application can be harvested through OAI-PMH protocol, which in turn allows for further creation of additional services by giving greater access and visibility to SciELO data in the new AGRIS AP format compared to the used DC format. The strategy that we adopted was to adapt BIREME’s OAI-PMH plug-in for direct generating of AGRIS AP XML fro m the SciELO application. The existing BIREME OAI-PMH plug-in interface was upgraded to accept and expose metadata using AGRIS AP in addition to the existing DC schema. This approach was elegant but required more time for realization and implementation by BIREME and FAO staff.
