Abstract. This paper describes the work done within the Food and Agriculture Organization of the United Nations (FAO) on providing an ontology-based navigation for the Food, Nutrition and Agriculture (FNA) Journal. The aim of the revised navigation was to provide more efficient and effective browsing of the Food and Nutrition Publications using a knowledge model to guide the user with concepts and relationships relevant to a specific subject area. With this approach, data from two different bibliographical databases was merged, unified and presented to the user with improved services. A preliminary metadata merge was needed to combine all the information into one system in order to produce a metadata-ontology. Resource Description Framework Schema (RDFS) was chosen to exploit semantic relationships, e.g. the possibilities of browsing the data in different ways (by keywords, categories, authors, etc.), and the creation of a multilingual concept-based advanced search.
