Résumé
Using standard formats such as OWL or SKOS has facilitated the development of a wide range of tools and applications for semantic artefacts. The challenge is now to package them inside semantic artefact catalogues where the cohabitation, interoperation and appropriate use of each type of semantic artefact (SKOS and OWL) will be possible. In this paper, we present the new functionalities to support SKOS resources in the AgroPortal (https://agroportal.lirmm.fr) vocabulary and ontology repository. We have created state-of-the-art innovative browsing approaches to discover and navigate SKOS concepts in thesauri that made an extensive use of scheme and collections. We have also enabled the use of mappings declared with SKOS properties.
