Hello,

I'd like to synchronise the contacts on my WebDAV server (here ownCloud but it should work with any CardDAV server) with my thunderbird address book.
After some hours of research, it seems there is NO vCard synchronisation extension out there working with recent version of Thunderbird (tried SOGo, ThunderbirdSync, Contacts, all outdated).

The only hope I have so far is with MoreFunctionsForAddressBook which handle well the vCard format. The idea is them : export the contacts in vCard and then synchronise the local file with my remote server. Doing that could also allow me to synchronise other source.

The problem is I'm not able to find a good library to handle CardDAV.
The only thing I've found is libcarddav from the trinity project but the documentation is not very clear and I'm not even sure it does what I'm looking for.

I try to have a contact synchronisation solution using as much as possible standard and open source solutions but it seems there is very little implemented with CardDAV (on the other hand CalDAV seems more popular). Is there a better standard out there ?
Do you know a software doing what I'm looking for or is it too exotic ?

Thank you
