We have developed a JavaScript User Interface (UI) hosted on GitHub Pages to facilitate neuroimaging communities'' involvement in annotating and sharing terminologies for neuroimaging datasets. The UI allows community curators to interact with their own terminology and reuse terms from other neuroimaging communities. It is designed around Git and GitHub version control systems, enabling direct interaction with the NIDM-Terms GitHub repository. The UI uses JSON-LD files from the NIDM-Terms GitHub repository in the background. Its functionalities include browsing, searching, and suggesting edits to available terms and properties, suggesting new terms, and exporting selected terms and properties in various formats such as Markdown, JSON, JSON-LD, CSV, and N-Quads. Additionally, the UI allows for adding new neuroimaging communities to NIDM-Terms. Visit the NIDM-Terms UI at https://nidm-terms.github.io/.
