User:Ruslik0/Flagged revisions

This is a technical proposal for the experimental implementation of Flagged Revisions on the English Wikipedia. The main purpose of it is conducting one or several trials in order to define the final configuration. The proposed setup is aimed at achieving the maximal flexibility, while retaining an ability to stop the experiment if trials are unsuccessful.

Main features

• Flagged revisions (FLR) are enabled over mainspace and portal space
• FLR are disabled by default. They can be enabled and configured on the article (portal) by article (portal) basis.
• Articles with FLR enabled can be rated on 3 scales: accuracy, comprehensiveness and style. Each scale has 5 levels (0=unrated, 1=acceptable, 2=average, 3=good, 4=featured). Pages that are rated at least (1,1,1) are sighted articles (portals). Those that are rated at least (3,3,3) are called quality articles (portals).
• Two new user groups are introduced: editors and reviewers. Editor can rate (review) pages up to the level 2. Reviewers—up to 4 (validate).
• Editor right is granted to everyone who edited at least 100 days, has at least 500 edits and more than 10 edits in the recent changes, has edited at least 50 different pages and made more than 300 contents edits. Editors are also required to use edits summaries at least 100 times. Reviewer permission can be removed and given by sysops and reviewers.
• Reviewer access is granted and removed by bureaucrats. Reviewers can validate articles and portals and enable/disable/configure FLR on page by page basis.

Trials. Technical guideline

A trial begins when there is a consensus. A bureaucrat appoints several reviewers who will be largely responsible for conducting the trial. A set of articles/portals is chosen and FLR are enabled over them. Unregistered readers will see either the last sight revision or last quality revision (depending on the nature of the trial). Any revision should be sighted (rated at level 1—acceptable) if does not contain obvious vandalism, libel or copyright violations. Quality revisions can be enabled over a small set of pages to test it as an alternative to semi-protection. In this case unregistered readers will see the last quality revision (rated as at least 3—good). A page should be validated if it is roughly of GA quality.

The trial ends when the trial period expires. A bureaucrat empties 'reviewer' group and then disables FLR over all pages that were part of the trial.

Notes

• 1. Automatic assignment to the 'editor' (sighter) group can be disabled. In this case rollbackers should be assigned all 'editors' rights by default.
