CalDAVCardDAVenabled

CalDAVCardDAVenabled is a descriptor used in software configuration to indicate that both CalDAV and CardDAV services are available on a system. CalDAV provides access to calendar data via WebDAV, using iCalendar format; CardDAV provides access to contact data via WebDAV, using vCard format. Enabling both means clients can synchronize calendars and address books from a single server endpoint.

In practice, the term may appear as a boolean flag, a capability tag, or an umbrella feature in configuration files or admin interfaces. Enabling it typically turns on a CalDAV server component and a CardDAV server component, often sharing authentication and storage backends.

Standards and capabilities: CalDAV is defined in RFC 4791; CardDAV in RFC 6352. Both support standard operations: create/read/update/delete (CRUD) on resources, with access control, and compatibility with iTIP scheduling for events. Servers may implement additional features like synchronization, scheduling, and push notifications.

Usage and compatibility: Many calendar and contact clients implement CalDAV/CardDAV, including desktop and mobile apps. Security considerations include using TLS, controlling access with authentication (e.g., Basic or Digest over TLS), and proper ACLs.

Examples and implementations: Open-source servers such as Radicale, Baikal, Nextcloud, and ownCloud provide CalDAV/CardDAV services; a combined "CalDAVCardDAVenabled" configuration flag is common in documentation for these systems.
