Currently MetricsGrimoire on http://korma.wmflabs.org/ has a backend to query Gerrit to create statistics like
- http://korma.wmflabs.org/browser/contributors.html (but cf. T118522: What is contributors.html for, in contrast to who_contributes_code.html and sc[m,r]-contributors.html and top-contributors.html?)
At some point (maybe first half of 2016?), Wikimedia will replace Gerrit by Phabricator's Differential.
We should have agreed on a basic plan and functionality scope what should be supported by MetricsGrimoire.
MetricsGrimoire will need backend adjustments in its code.
- No need yet to investigate deeply.
- Bitergia to check out the the API of Differential.
- Wikimedia to review which metrics we want (or might not need).
