Nuria,

thanks for the feedback – for context, the reason why I am asking is that: 

• I was under the impression that this data was already being stored somewhere in temporary tables by Wikimetrics when generating project-level reports
• this is quite similar to one of the earliest feature requests that we had for UserMetrics (the predecessor of Wikimetrics) under the notion of “generated cohorts”:

1) take the non-aggregate output of a report (say all registered users or new active editors from foowiki in a given time period)
2) save the output as a cohort
3) re-run that cohort through a different metric

Using Quarry still relies on the end user’s ability to understand how to turn a research question into a query. Having a curated query library is a good step in that direction, but that still requires some basic knowledge of SQL.

There are no technical blockers to be able to generate that data. Now, product wise it does not seem like a fit as wikimetrics' purpose is to produce data and run metrics. All wikimetrics computations are pre-canned. 

It seems to me the use cases you passed along are better fitted by a tool being able to freely query the db like quarry.

Thanks,

Nuria

Abbey asked a question during today’s research group that I wanted to relay to the wikimetrics devs.

Would it be possible to allow people to use Wikimetrics’ project-level reports to generate cohorts, in other words, obtain lists of user_ids or user_names matching specific criteria, for example:

• registered users on a given date or period
• newly active editors on a given date
• unique editors on a given date or period

UX research as well as LCA would die to have such a functionality (the fallback is to do this via Quarry or post a request to Research & Data or someone in Grantmaking).
