Re: Tracking Preference Expression Spec Suggestion

Andy

do you have specific suggested edits, or suggested edits in specific places, that you think would help clarify this?

This is less likely (in my estimation) to be enacted by a user than a  opt-out choice delivered at the time of transaction. At the very least, the latter should be considered as potentially beneficial, and I'd like to see the spec reflect directly that in addition to DNT:1 excepted to DNT:0 in some cases, it is advisable to build a mechanism for DNT:no prefrence excepted to DNT:1.

I'm not entirely sure I understand the suggestion: is the idea that the header mechanism could be used to send DNT:0 to certain sites (even when Do Not Track was not broadly enabled) to indicate consent for tracking? I believe that possibility is covered in part by "6.6 Exceptions without a DNT header" http://www.w3.org/2011/tracking-protection/drafts/tracking-dnt.html#exceptions-when-not-enabled

I believe that's also compatible with the current text of the specification, but maybe that isn't clear to readers (or perhaps others in the Working Group even disagree).

This section generally deals with the notion that the DNT preference has been enabled in a browser and an exception should be made - that is - DNT is set to 1 by policy but should be set to 0 in a specific case.

I propose that this notion of DNT inclusion (rather than exception), available whether or not they've made prior user-agent policy decisions,  be captured in the document. This woud enable (and encourage) context-based solutions like the platform Evidon provides to adopt the DNT header along with current cookie-based opt-outs, without relying on the user to make a top-level browser configuration decision about DNT.
