Rob,

I'm the Chair of the Metadata Working Group at the IAB so thank you for calling that out.  But understand even that standard will take time to roll out and is meant to compliment - NOT DISRUPT - the current workflow.  The discussions around RTB are highly disruptive and BREAK the current model - with no easily solutions at hand.  That is my core concern - there is a lack of consideration within the group of this critical dynamic.

- Shane

Well, change is a constant factor. For example, the IAB is working on adding metadata all the way down the ad chain. There is no reason why the current protocols are cast in stone. The whole purpose of DNT is to have in impact on current ad practices.
