This demo paper describes the technical architecture and features of IndustryPortal (http://industryportal. enit.fr), a dedicated open-source platform designed to develop, publish, and maintain FAIR (Findable, Accessible, Interoperable, Reusable) ontologies-and more largely semantic artefacts-in the industrial domain. The primary objective of this semantic catalogue is to enhance the interoperability of ontologies, increase their reusability, and ensure that they meet the high-quality standards demanded by the industrial community. IndustryPortal has been developed in the context of the H2020 OntoCommons project, released in March, 2022 with a robust plan for long-term support. The portal is based on the open source and shared OntoPortal technology.
