Dear all,

I performed an empirical study of the interoperability of the vCard format:

http://alessandrorossini.org/2012/11/15/the-sad-story-of-the-vcard-format-and-its-lack-of-interoperability/

This study shows that common contact information is often represented by grouped properties and non-standard properties. These properties are not interoperable and make the import/export of vCard files as well as the synchronisation via CardDAV unreliable.

In my opinion, the IETF should remove grouped properties and non-standard properties from the specification, even if this would break backward compatibility. Moreover, the IETF should add social networking properties to the specification. Finally, the IETF should provide an official validator for vCard files.

Any comments?

Best regards,
