Abstract
The OntoPortal Alliance is a consortium of several research and infrastructure teams and a company 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 resource 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. 26 to 29th, 2023 in Lecce for the 2nd OntoPortal Workshop. The meeting gathered around 30 persons including management, research and technical profiles (25 on site and 5 remotely). The 2023 workshop's main goals were to consolidate the OntoPortal Alliance organization and shared agenda, and to inform and engage the larger scientific community interested in the OntoPortal technology. The program included several sessions (technical, content, management) and a set of public sessions including a general presentation of OntoPortal, a user panel and Q&A session with representatives of different communities and a tutorial. The event was also associated with the FAIR-IMPACT Semantic Artefact governance workshop. Topics selected at the agenda included: multilingualism, federated services and metadata, ontology versioning, documentation and training, mappings, code management, and general governance of the Alliance.In preparation of the event, a survey gathered the partners' perceptions with respect to each topic selected for the agenda of the meeting. In addition, each team presented short updates of their project (available here (private folder)). 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.
