Thanks Dan. I told Toby he should subscribe to this list :)
Regarding #1 another option could be to: • only allow user_ids as keys (after all most JSON consumers prefer to work with user_ids) but add user_names as attributes • return both user_ids and user_names as separate columns in flat CSVs.
Either way, it sounds like this would be a great addition for Wikimetrics customers.

These things have definitely been discussed before, so it's time to get them prioritized. CC-ed Toby directly so he can follow up:
- wikimetrics should allow user_name to be the key in report outputs. Right now, only user_id is allowed and this is not great. LiAnna, Jaime, and Jessie are definitely interested in this, and have mentioned it a few times.
- wikimetrics should allow "generated cohorts" as implemented by user metrics api. These are cohorts defined by reports on other cohorts. For example, if we run report R on cohort C, then generated cohort (GC) would be: GC = {user | user in C and R(user) is true}. Dario is definitely interested in this, and Jaime might be as well.

Often the data makes me want to investigate the individual stories of contributors who added a lot of content/made a lot of edits/etc., but there's no way of doing that with user IDs since I can't convert user IDs to usernames.

Dan, any thoughts?
BTW this notion of rerunning cohort analysis for members of a previous cohort who meet specific criteria is a use case that Product/Editor Engagement is also interested in. We used to call these “generated cohorts” in the old design plans for UserMetrics and I’d love if we revisited this feature requests and its relative priority.

Missed the question back to me, sorry. Mixed cohorts might occur due to the output as user IDs while collection is of usernames - say someone has a repeating events and has a csv output of data for those new users that were retained at a certain activity level from Point A to B and then has new cohort members opt in at Point B but only wants to include those that already survived from Point A and new at Point B cohort members for examining at another Point C. Without the output of usernames to create the active Point B cohort separately this would make the Point C cohort a mix of qualified user ids and new user names. There are several ways of dealing with this, it was just the first scenario I could think of that could cause this. Seems we still need to revisit the possibility of accessing usernames as output, also for reasons of matching to other data points where most users and most program leaders do not know user ids - Jaime

Jaimee – can you give us more details on the use case for mixed cohorts that you had in mind?

So, for now, until I figure out how to fix this, it will always prefer user_names before user_ids.
I think this is an argument for making users specifying whether it's names or ids up front, and not allowing mixtures. Assuming it might be a mixture and looking for names first is almost certain to produce inaccurate results at some point. We have ids precisely to avoid collisions with names, allowing for renaming users, and other cases.
Yep, I just learned this the hard way and made a fool of myself in front of a bunch of people I admire. So, I'd be glad if I'm the only one that this happens to. If nobody objects, I'm going to allow the user to select whether their cohort contains user_ids OR user_names, and strictly prohibit mixtures.
