Tuesday agenda item

Hi Everyone

I would like to propose an addition to the agenda for 7/14 to discuss two
additional modifications/clarifications to the Turtledove/Sparrow
discussion. These contributions are listed below. The purpose of these two
papers is to drive further discussion on a workable model for Cohort
creation and management, with the key focus being driving an environment
that is actually implementable and manageable over the long term.

The general principles here are:
no identifiers can be passed between buyers and sellers.
some identifiers may exist for cohort creation, and those identifiers could
potentially be used by either a publisher or a browser, or both
If a browser has access to an identifier for cohort creation, there should
be a method for allowing a non-browser entity to do the same, under
understood guidelines. In other words, all intelligence and decision making
cannot be self-contained in the browser with no transparency, auditability
or visibility by the rest of the ecosystem.

These two proposals are different ways of looking at the above problem. One
of the proposals (gatekeeper) requires a governance structure of some sort
to insure that the functions are properly conducted. The other (Prop
Cohorts) does not, as the governance is self contained in the signalling
between the browser and the publisher/federation.

We would like 10 minutes to cover the basics of these proposals, then we
also propose 5 minutes to discuss as a group how to handle further
modifications to the Sparrow-Turtledove military industrial complex of
things, and ensure that we are correctly covering the pros and cons with
the relevant stakeholders. This proposed review would be in
conjunction/cooperation with Criteo ie the authors of Sparrow, as these
modifications were developed collaboratively.

Thanks.
