The Tracking Protection Working Group is
chartered to improve user privacy
and user control by defining mechanisms for
expressing user preferences around Web
tracking and for blocking or allowing Web
tracking elements. The group seeks to
standardize the technology and meaning of Do
Not Track, and of Tracking Selection Lists.
Carl Cargill (Adobe), Justin Brookman (Invited Expert) and Matthias Schunter (Intel) serve as
co-chairs of the Tracking Protection Working Group. The W3C Team Contact is Nick Doty.
Call for Comments
On 14 July 2015, the Working Group published a Last Call Working
Draft of the Tracking Compliance and Scope specification. Comments and
reviews are invited by 7 October 2015. If you wish to make comments regarding
this document, please send them to firstname.lastname@example.org
All comments are publicly archived; if you have not used W3C mailing lists in
the past, you will need to approve archiving (instructions are sent via email
auto-reply) before your comments will be distributed. You do not need to
subscribe to the mailing list to send comments. Contact Nick Doty, Team Contact, with any problems
The Tracking Protection Working Group invites broad community
review, especially of technical requirements and dependencies.
Reviewers are encouraged to comment on the extent to which technical
requirements of the group's charter have been met and how significant
dependencies with groups inside and outside W3C have been satisfied.
The Working Group will evaluate all comments received and determine
whether or how the specification needs to be modified in light of the
comments. Comments will be most useful in identifying particular
problems with the specification that might inhibit adoption, or where
this specification fails to further goals of user privacy and user
control, and whether this specification creates or does not otherwise
resolve dependencies with other technical standards, practices, or
processes. The Chairs of the Working Group will issue written responses
to all comments received.
