The CESSDA Vocabulary Service (CVS) allows communities and organisations to host and publish their own vocabularies for users to search and download. For this, CESSDA has developed a tool that provides both a discovery interface where vocabularies can be searched, browsed and downloaded and an editing interface where the vocabularies are managed and translated. The editor also includes an access and user management interface and allows versioning with persistent identifiers and citation of the controlled vocabularies. All content is available through an API. This document specifies the different roles and responsibilities related to the CESSDA Vocabulary Service.
