Résumé
Research in Agri-food and related fields dealing with sustainability has undergone important changes in the past years and tends to be more integrative, collaborative, and interdisciplinary. In this article, we present an excerpt of recent and ongoing projects in the French community proposing data integration guided by an ontology for collective decision support in the Agri-food domain. The use of ontologies for primary production and secondary production, i.e. transformation of primary production into food products, are addressed. An example of collective decision support system for food packaging selection which relies on scientific data annotated thanks to ontologies and food chain stakeholders’ preferences is described. French initiatives at the international level to share agri-food ontologies are presented.
