Data portability and interoperability with JMAP for Nextcloud
Frank Dengler CEO audriga

Frank is the CEO and co-founder of audriga, a company pioneering data portability since 2011. audriga supports hosters and telcos of all sizes with white-label self-service customer onboarding and large-scale multimillion account platform migrations. audriga can migrate nearly any kind of data such as files, emails, contacts, calendars, account settings and rules between virtually any type of system.

JMAP provides a modern, standardized API (protocols and data types) for email, contacts, calendars, and more. It was built on the experiences of IMAP, CardDAV, and CalDAV, with improved performance, interoperability, and data portability as its major goals. JMAP specifications are published as IETF RFCs. Additional information and forthcoming work is available at

The OpenXPort project, supported by the EU Next Generation Internet data portability incubator (DAPSI), develops Open Source components to support the adoption of JMAP. This includes a JMAP app for Nextcloud (, which currently supports Nextcloud contacts and calendars.
