nextcloud/metavox

MetaVox is an open-source Nextcloud app that adds structured semantic metadata to documents, enabling easier organization, interpretation, and retrieval. Developed by the University of Amsterdam and the Amsterdam University of Applied Sciences, it is designed for universities, government organizations, and knowledge workers who need enhanced metadata capabilities beyond Nextcloud's basic features. The app allows administrators to define and manage metadata for team folders, while users can view or edit document-specific metadata based on their permissions, making it ideal for document-driven environments like education, research, and administration.
