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

One of the problems in collaborative networks of documentation centers is the lack of interoperabilitybetween 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 paper 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.
