+    <h2>Summary</h2>
+    <p>
+    Many vocabularies and ontologies are produced to represent and annotate agronomic data. It is therefore necessary to have a common platform to identify them, host them and use them in agro-informatics applications. The AgroPortal project aims to provide a repository of reference ontologies for agronomy, by reusing the NCBO BioPortal technology. The scientific results and the experience of the biomedical field are thus exploited and transposed in the field of agronomy, including plants, food, the environment and possibly animal sciences. We propose an ontology portal that offers ontology hosting, search, versioning, visualization, commenting, recommendation, allows semantic annotation, as well as storing and exploiting alignments of ontologies. All this in an infrastructure fully compliant with the Semantic Web. The AgroPortal project pays particular attention to meeting the requirements of the agronomic community in terms of ontology formats (e.g. SKOS, trait dictionaries) or supported functionalities. The AgroPortal project is based on five agronomic use cases that participate in the design and orientation of the platform. AgroPortal already offers a robust and stable reference repository, of great value for the field of agronomy.

+    <h2>Résumé</h2>
+    <p>
+    De nombreux vocabulaires et ontologies sont produits pour représenter et annoter les données agronomiques. Il est donc nécessaire de disposer d'une plateforme commune pour les identifier, les héberger et les utiliser dans les applications d'agro-informatique. Le projet AgroPortal vise à offrir un référentiel d'ontologies de référence pour l'agronomie, en réutilisant la technologie NCBO BioPortal. Les résultats scientifiques et l'expérience du domaine biomédical sont ainsi exploités et transposés dans le domaine de l'agronomie, comprenant les plantes, l'alimentation, l'environnement et éventuellement les sciences animales. Nous proposons un portail d'ontologies qui offre l'hébergement d'ontologies, la recherche, la versioning, la visualisation, le commentaire, la recommandation, permet l'annotation sémantique, ainsi que le stockage et l'exploitation d'alignements d'ontologies. Tout cela dans une infrastructure totalement conforme au web sémantique. Le projet AgroPortal accorde une attention particulière au respect des exigences de la communauté agronomique en termes de formats d'ontologies (par exemple, SKOS, dictionnaires de traits) ou de fonctionnalités prises en charge. Le projet AgroPortal est basé sur cinq cas d'utilisation agronomique qui participent à la conception et à l'orientation de la plateforme. AgroPortal offre déjà un référentiel de référence robuste et stable, d'une grande valeur pour le domaine de l'agronomie.
