Résumé
The OntoPortal Alliance is a consortium of several research and infrastructure teams dedicated to promoting the development of ontology repositories ––in science and other disciplines–– based on the open, collaboratively developed OntoPortal open source software. Teams in the Alliance develop and maintain several openly accessible semantic artefact catalogues or ontology repositories in multiple disciplines. The list of repositories is available on the Alliance web page and the teams are listed on GitHub. The OntoPortal Alliance members and other partners gathered from Sept. 23 to 26th, 2024 in Stanford for the 3rd OntoPortal Workshop. The meeting gathered around 20 persons including management, research and technical profiles (13 on site and 7 remotely). The 2024 workshop’s main goals were to consolidate the OntoPortal Alliance organization and shared agenda, and to engage with newcomers. The program included several sessions (technical, content, management) as well as a newcomers session which featured three new use cases in astronomy, cultural heritage and for general semantic web vocabularies (LOV).The workshop allowed the Alliance to re-align on the questions related to the management of the upstream OntoPortal code repository (https://github.com/ontoportal), as well as the distribution of the OntoPortal virtual appliance. Multiple new interfaces and new features were demonstrated such as URI management or new search or SPARQL query capabilities. The workshop also demoed the first federation of four OntoPortal-based repositories with the upcoming federation joint release of Agro/Eco/Earth/BiodivPortal. Different prototypes were presented including revised work related to the Annotator using LLMs, a (BioPortal-based) CustomGPT. The event demonstrated the clear motivation and commitment of the Alliance members to collaborate on the OntoPortal technology and the implementation of ontology-based services in general. This document is a summary of the discussions and the decisions taken.
