Technical Summary
   The METADATA extension to the Internet Message Access Protocol
   permits clients and servers to maintain "annotations" or "meta data"
   on IMAP servers.  It is possible to have annotations on a per-mailbox

   information to be made available to anyone logging in to the server.

  It was informally last called in the IMAPEXT WG and was discussed
  in several WG meetings.  It was also reviewed by lemonade WG
  participants for interaction with other IMAP extensions.
Protocol Quality
  This was reviewed for the IESG by Chris Newman.  This proposal has
  been discussed extensively and is leveraged by upcoming extensions
  from the lemonade WG.  There was a proposal to add multi-valued 
  attributes, but it was not accepted due to existence of a
  work-around using subordinate entries.  This area might need
  further feedback from client implementors.  There have been
  ongoing requests for this functionality for many years, but also
  ongoing concerns about the level of complexity in this proposal.
  There are already 2 server implementations of earlier versions of
  this document.  At least one client and one server vendor are
  interested in implementing the specification.  Francis Dupont
  performed GEN-ART review.

  After the first last call for this document, an effort was made
  to greatly simplify this proposal resulting in a second last
