Synopsis (short abstract) 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.

    Towards a harmonization of metadata application profiles for agricultural learning repositories 2008

    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.

    Comparing Different Metadata Application Profiles for Agricultural Learning Repositories 2009

    Agricultural learning repositories can provide new opportunities for sharing, accessing, using and reusing learning resources online. Metadata plays a crucial role in such systems: apart from simply indexing resources, metadata makes it easier to discover a learning resource in a repository, as well as to decide about ways to use it for teaching or learning purposes. In the context of agricultural education and training, a variety of appropriate metadata standards may be selected, adapted and im plemented for a learning repository. In this paper we introduce the concept of metadata for agricultural learning resources, and compare two particular cases: one application profile based on the Dublin Core Metadata Element Set (DCMES) and the other based on the IEEE Learning Object Metadata (LOM). The paper attempts to identify similarities and differences between the two case studies and to outline issues that have to be resolved in order to harmonize such efforts.

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

    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.
