CardDAV

CardDAV support includes address book collections and vCard resources.

Cards are stored exactly as uploaded. The server advertises both:

• vCard 3.0
• vCard 4.0

Clients can negotiate text/vcard; version=4.0. The default response favors vCard 3.0 for compatibility with common clients.

jCard can be negotiated through sabre’s converter, though most clients use text/vcard.
