Re: Do Not Track TPE Last Call Comments

Mr. Narayanadas,

Thank you for your comments (last June) on the Tracking Preference Expression Last Call Working Draft.

The decision to define the term tracking in the TPE was previously resolved by the group; you do not provide new information to justify reopening this long-discussed issue.

The requirements on when user agents may send DNT:1 signals on behalf of a user as detailed in Section 4 of the TPE. The group previously rejected providing more detailed requirements; you do not provide new information or a proposal to cause us to reopen this issue. We revisited this issue during the Last Call process in considering a proposal to require information about the DNT setting party within the DNT field, but that proposal was rejected by the group.

As communicated to you previously, we revised the TPE to address your concern about how DNT would operate in the RTB environment: https://lists.w3.org/Archives/Public/public-tracking-comments/2015Jun/0006.html

Please let us know whether these changes or explanations resolve your concerns.

Thanks,
