[patwg] Agenda Request - Intermediaries using the Level 1 API (#44)

martinthomson has just created a new issue for https://github.com/w3c/patwg:

== Agenda Request -  Intermediaries using the Level 1 API ==
## What can we do for the Level 1 API that is most effective for intermediaries

We all know that intermediaries (DSPs, SSPs, etc...) will be the most likely users of any API, especially in the beginning.  Therefore we need to make sure that the API is good enough for them to get what they need, without a whole lot of complexity.

This might need to follow on from #40, where we will look at a broader set of use cases.  However, I'd like to focus this effort on answering some of the outstanding API issues around how intermediaries engage with the API.

This includes:

* If an intermediary saves an impression, who can access that impression? (See https://github.com/w3c/ppa/issues/26 and https://github.com/w3c/ppa/issues/55)
* How does an intermediary measure conversions?  What impressions can they see? (See https://github.com/w3c/ppa/issues/102)
* We have basic delegation, where a site can give intermediary the ability to spend their privacy budget, but is there a better model?  Here, I want to go through https://github.com/w3c/ppa/issues/38 and put some more substance on that, enough that editors could go ahead and implement that API.

Hopefully we can make progress on the cluster of issues that all relate to intermediaries https://github.com/w3c/ppa/issues/32  This won't be the full set of capabilities that we have discussed, which includes an HTTP API for delegation and giving intermediaries their own budget for making queries.

My sense is that once we have something for this, the HTTP API will follow pretty naturally, but we might need to keep the own budget idea as a level 2 goal.  I understand Roxana has made significant progress on the formal analysis side of the intermediary budgeting problem, so we might still want to spend time on the question during the meeting.

## Time

I have two parts to the discussion so far: a relatively simple question (20 minutes would be a guess) and a harder one (40 minutes).  I could be wrong about the split, but it seems like the overall question is worth an hour.

### Links

I've linked issues above.  I have draft slides, which I'll send a link to once they are a bit clearer.
