Provenance

In order to evaluate the effectiveness of social sharing and other similar efforts for Wikimedia projects, a parameter "wprov" can be appended to URLs on a case-by-case basis. This page exists to keep track of reserved values.
The value of this parameter will be recorded in the X-Analytics field of the webrequest table (as x_analytics_map['wprov']). Requests with different "wprov" values will not be cached separately (as it would be the case with other, arbitrary parameter names), thus avoiding cache fragmentation.
== Description of wprov parameter ==
The format of the parameter name is ?wprov=<3_char_feature><platform_one_char><major_version_of_feature_uint>.
See the Analytics mailing list thread and Phabricator task T90606 for further background.
