Currently MetricsGrimoire on http://korma.wmflabs.org/ has a backend to query Gerrit to create statistics like
* http://korma.wmflabs.org/browser/scr.html
* http://korma.wmflabs.org/browser/scr-contributors.html
* http://korma.wmflabs.org/browser/gerrit_review_queue.html
* http://korma.wmflabs.org/browser/code_contrib_new_gone.html
* http://korma.wmflabs.org/browser/contributors.html (but cf. {T118522})
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).
