Dear Advisory Committee Representatives, Working Group participants, and Chairs,

Based on the successful completion of its deliverables, the P3P Specification
Working Group is now closed.

The group has an impressive record of successful creation and deployment of
P3P (the Platform for Privacy Preferences), W3C's privacy framework. The group
delivered the P3P 1.0 Recommendation, a landmark in online privacy.

Please join us in congratulating all participants. We wish to thank Lorrie
Cranor, Chair, for her leadership and contributions to W3C.

More information about the P3P Specification Working Group is available on
their home page:


The group has completed its work on P3P 1.1 by delivering a Last Call Working
Draft. Following the change in the privacy landscape following the 9/11
events, the group found there is insufficient momentum for implementations at
this point in time. Although they believe that P3P 1.1 is ready for
implementation, the group decided not to enter Candidate Recommendation,
published the current specification as a Working Group Note, and have thus
completed their last deliverable.

P3P Specification Working Group Achievements

The P3P Specification Working Group was chartered to maintain P3P 1.0, to
create an improved P3P 1.1 specification, to provide advice on privacy issues,
and to liaise with other groups. It was also chartered to explore further
development work in the privacy area. During its lifetime the group produced
these W3C technical reports:


  The Platform for Privacy Preferences 1.0 (P3P1.0) Specification
    16 April 2002

Working Draft

  A P3P Preference Exchange Language 1.0 (APPEL1.0)
    15 April 2002

The group organized three W3C Workshops on privacy:

  The Virginia Workshop on near term improvements
    November 2002
    W3C Workshop on the Future of P3P

  The Kiel Workshop on long term future
    June 2003
    W3C Workshop on the long term Future of P3P and Enterprise
    Privacy Languages

  The Ispra Workshop on negotiations and semantic driven enforcement
    October 2006
    W3C Workshop on Languages for Privacy Policy Negotiation and
    Semantics-Driven Enforcement

Next Steps

After the very successful completion of the Ispra Workshop, there is a
community that needs more discussions before starting further work. So the
Privacy Activity expects to propose an Privacy Interest Group chartered to
discuss concrete next steps and to maintain the high level community around
privacy in W3C.

This announcement follows the Process Document section 6.2.8 "Working Group
and Interest Group Closure." [1]
