FlaggedRevs是MediaWiki軟體的擴展，它能讓維基監視對頁面做出的更改，並更謹慎地控制向維基讀者顯示的內容。 頁面可以由某些編輯者和審核員標記，以表示這些頁面已經被審核並確認符合維基所要求的標準。 該頁面的每個後續版本都可以被這些用戶標記以用來審核新的更改。 維基可以使用不同的標記，並只允許某些用戶能夠設定這些標記。

標記修訂讓維基可以定義應用於頁面修訂的「標誌」，以表示該版本的品質或其他屬性。 Flags form a hierarchy.
Marker是抽象的標誌分組，用於辨識具有特定品質的條目。 There is only one marker available, "reviewed". 預設情況下，任何修訂版本在任何維基標準被標記為任何等級皆會符合「已檢查」marker。 大多數維基將定義他們自訂的標誌準則，因此這些設定將有所不同。
FlaggedRevs allows a wiki to mark each revision of a page with a flag to indicate its quality or validity, and to control which revisions are shown by default on a page.
Each page where FlaggedRevs is enabled is effectively given two alternative aliases; these are the "stable" version, which is the latest version that has been flagged to a sufficiently high level, and the "current" version, which is the most recent revision, flagged or not.
Readers can access either version of the page by adding
&stable= to the URL in the address bar, setting
&stable=0 for the current version, and
&stable=1 for the stable version.
On each alias, there is an explanation and a link to the other version.
Wiki developers can control which alias is displayed to users and readers by default, and which flags allow a version to be considered 'stable'. Registered users can customize which alias they see by default in their User Preferences. Editors are also made aware of which alias they are viewing by the "编辑" tab, which instead displays (by default) "edit draft".
FlaggedRevs does not affect a user's ability to edit a page; only the way the resulting version is handled by the wiki. Whenever a user edits a page, the contents of the edit window are always the wikimarkup for the current version, to prevent revision forks from accumulating. When there are unreviewed changes made since the last stable version, a diff is provided above the edit window to highlight any changes. This is important as the text being edited may not be the same as the page the user viewed before clicking the "编辑" link (if the user was viewing the stable version); and it allows any changes to be immediately reviewed and modified or reverted if necessary.
If the user will not be able to see their changes in the default alias, an additional warning message is displayed, by default "edits to this page will be incorporated into the stable version once an authorized user reviews them". Other than this the editing process is unchanged by FlaggedRevs; edits are made, previewed and saved in the normal manner.
Users who are capable of reviewing edits are encouraged to do so both during and after they edit. There is an option next to the "这是一次小编辑" and "监视此页面" checkboxes to immediately review the version resulting from that edit, although this option is unchecked by default. Once a reviewer has made an edit, they are returned to the article as normal, but are presented with a diff of all changes, including theirs, since the last stable version, with the option to immediately review the changes.
Reviewing versions is the primary new activity introduced by FlaggedRevs. With the exception of the "review this edit" checkbox on the edit screen, all methods of reviewing versions use the same interface. At the bottom of a draft page, a series of radio buttons or checkboxes allows the reviewer to select which flags to apply to the revision, and there is the option to provide a comment that will appear in the review log.
Users can review any version, including versions that have already been reviewed by others. In this instance the newest review overrides previous reviews: if the new reviewer flags the version at a higher level than the previous reviewer, it is considered a normal "approve" review, while 'confirming' another reviewer's assessment by flagging the version to the same level is recorded as a "re-review". By flagging a previously-reviewed version as 'unassessed', reviewers can effectively 'unflag' a revision; these "deprecations" can be seen in a separate stream in the review log.
FlaggedRevs is designed to encourage eligible editors to review versions quickly and efficiently, and so links are provided in most common locations to review changes by editors who cannot flag the versions themselves. Edits that have resulted in an unreviewed version are marked with an exclamation mark ! in the watchlist and the RecentChanges feed, with a link to review the changes. When viewing a page that has unreviewed edits, a banner is also added to indicate the number of edits since the last stable version, the age of the stable version, and a link to review the changes.
The FlaggedRevs extension also creates a number of new special pages that can be used to find and manage reviewed and unreviewed pages:
- Special:PendingChanges (called Special:OldReviewedPages on some wikis) - pages that have pending changes from the stable version.
- Special:UnreviewedPages - pages that have no reviewed stable version.
Special:UnreviewedPages also includes the number of users who have each page on their watchlist, so that 'backwater' articles can be identified and monitored; because of this slightly sensitive information, access to Special:UnreviewedPages page is usually restricted to users who have the ability to review versions. Special:OldReviewedPages is sorted by the time since the last revision was flagged, oldest first.
Special:Contributions can be used to see pending edits by a particular user.
This feature is not yet available on wikis with Flagged revisions configured in the protection mode.
In addition to these pages, several other reports give general oversight over the reviewing process. Special:ConfiguredPages is a list of pages where the default display settings have been overridden by administrators to either always show readers the "stable" alias by default or always show readers the "current" alias by default, depending on the wiki's FlaggedRevs settings.
Finally, Special:ValidationStatistics provides a summary of how thoroughly each content namespace has been reviewed, and other useful data about the reviewing process.
Wikis can configure FlaggedRevs to automatically grant editors the ability to review versions when they meet certain thresholds of activity.
Wikis need to judge carefully how best to configure the autopromotion feature (if at all) to be as confident as possible that the user is a constructive editor, without making them wait too long to be promoted. Thresholds can be set on a number of attributes, including:
- Their total editcount
- It can be required that these edits have been made consistently over a time period, eg 20 edits spread over a period of 20 days would qualify, but 20 edits all at once would not
- Edits from the last X days can be excluded from the count (giving admins time to look at them)
- A certain number of these edits can also be required to be in "content" namespaces
While a wiki's developers can define default settings for which alias is presented to each user group by default, these settings can be customized by individual users and for individual pages. Each registered user can set in their preferences whether they wish to see the "current" or "stable" alias by default when viewing an article.
Some group on the wiki, usually administrators, have the ability to use the special page Special:Stabilization to override the default display for unregistered users. Administrators can set a page to display the stable version by default, and can also control how the stable version is selected, choosing which marker is preferred.
Administrators also have the ability to grant users the ability to review edits, and to revoke that permission in case of abuse, by using the Special:UserRights interface. This explicit assignment overrides any permissions automatically given to the user by the autopromote feature – if an administrator has explicitly revoked a user's reviewing permissions, the autopromote feature will not grant them back, and vice versa.
