Charter (as of 2011-12-09)

A personal address book (PAB) contains a read/write copy of attributes
describing a user's interpersonal contacts. This is distinct from a
directory which contains a primarily read-only copy of users within an
organization. While these two data objects share a large number of
common attributes, their use and access patterns are fundamentally
different. The IETF has a standards-track data format (vCard 4.0) and an
access protocol (CardDAV) for the interchange of both PABs and user
directory entry data objects.

Having completed its work on the base vCard and CardDAV specifications,
the VCARDDAV working group currently focuses on extensions to those two
technologies. In particular, the WG will complete the following work:

(1) A limited set of extensions to vCard (and its XML representation) as
well as to CardDAV. Extensions are accepted for group consideration
based on normal IETF consensus rules and in consultation with the
responsible Area Director.

(2) A lossless mapping between LDAP and vCard 4.0.
