    Generating AGRIS AP XML from local databases 2005
    Also available in:

    This document provides detailed technical information for converting bibliographic data from local databases into valid AGRIS DTD compliant XML records. The process that is to be carried out is, to some extent, complex. However, the result will benefit the Institutions and Centres that produce bibliographic data of agricultural content, in the conversion to XML data that can be disseminated to and harvested by the AGRIS XML repository. The XML repository is aggregated, maintained, organized and made available via the Internet. The main purpose of this guide is to facilitate the conversion process thorough step-by-step instructions and to provide a list of common pitfalls.

    FAO's experience in metadata exchange from CDS/ISIS bibliographic databases using XML format, compliant to Dublin Core standard 2006

    One of the problems in collaborative networks of documentation centers is the lack of interoperability between the different types of systems and applications used. The metadata is created in various places, time and using a number of tools and applications, data structures, content types, formats, and standards that may vary according to local needs. Exchange specifications that identify a minimum set of common requirements can be used for to facilitate the exchange and re-use of data. This p aper summarizes FAO’s experience in the efficient management and use of multilingual bibliographic CDS/ISIS databases, applying DC metadata standards and tools for search and exchange of bibliographic metadata. It explains in detail different approaches on how the bibliographic data from the CDS/ISIS databases can be converted and exported according to the Dublin Core (DC) and Agricultural Metadata Element Set (AgMES) based metadata set for cohesive and efficient platform-independent exchange of metadata. The second point is how different database applications can be united in a common search interface using DC elements. In addition, export features of DOS-, WINDOWS- and WEB-based CDS/ISIS application systems tools are compared. A number of examples on how the data in various input and storage formats can be reformatted without any modifications to the existing CDS/ISIS database and applications. The experience was gathered while working with FAO’s on-line library catalogue ( FAOBIB) and the International Information System for the Agricultural Sciences and Technology (AGRIS). The solution adopted was to use the Dublin Core (DC) and Agricultural Metadata Element Set (AgMES) based metadata set for the platform-independent exchange of metadata between existing databases.

    Scielo articles available to the agricultural community using OAI-PMH in AGRIS AP XML Format 2008
    Also available in:

    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.
