This document announces the formation of the W3C Data Privacy Vocabularies and Controls Community Group (DPVCG). The DPVCG was initiated based on outputs from a May 2018 workshop including use cases, requirements, and the identification of existing relevant vocabularies. The goals of the DPVCG include defining a set of vocabularies to support data privacy concepts like those in the GDPR, and hosting future meetings in August and November 2018 to further their work.
