![]() | This page in a nutshell: Most types of content forks are acceptable. The two types that are not are POV forks, in which articles are split up so that one can advocate a different stance on the subject, and pages of the same type on the same subject (also known as "redundant content forks"). |
A content fork is a piece of content (such as an inter-wiki object, a page, or a page section) that has the same scope as another piece of content that predated it, essentially covering the same topic. A content fork is acceptable or unacceptable depending on its type. Content forking is the act of creating a content fork. Transclusions are not content forks, because they do not diverge from the originals (usually templates).
As articles grow, editors are encouraged to create summary-style spin-offs or new, linked articles for related material, to make articles clearer and easier to manage.
While content forks that are different page types covering the same subject are acceptable, they should not contradict each other—contradictions should be corrected or removed.
When a content fork occurs by the creation of a pair of pages of the same type (such as two articles, or two templates, or two outlines) on the same subject, it results in two different versions of the same thing, which is unacceptable. The new page in such a pair is called a "redundant content fork". Content fork articles created unintentionally result in redundant or conflicting articles and are to be avoided, as the goal of a single source of truth is preferable in most circumstances. Therefore, it is important for an editor to check, before creating a new article on a particular subject, that there isn't already an article covering that subject.
A point of view (POV) fork is a content fork deliberately created to avoid a neutral point of view (including undue weight), often to avoid or highlight negative or positive viewpoints or facts. All POV forks are undesirable on Wikipedia, as they avoid consensus building, which violates one of our most important policies.
Etymology
editThe reason they are called "content forks" is that, like a software fork, even if one started off as an exact copy of another piece of content, the two pieces, being independently editable, may diverge over time, until they include different and possibly even conflicting facts about the topic.
Unacceptable types of content forks
editWhile most types of content forks are acceptable, it is especially important to watch out for the unacceptable kinds...
Pages of the same type on the same subject
editIt becomes a problem when there are two articles about the exact same thing, or any two pages of the same type covering the same thing as each other, such as two outlines, two portals, two templates, two categories, etc. Imagine if 100 editors each wrote a separate article on the dog and Wikipedia displayed them all. That would defeat the collaborative purpose of the wiki, and it would make managing information on dogs 100 times more difficult.
A page that covers the same subject as another page of the same type is often called a "redundant content fork". The most common occurrence of redundant content forks results in two articles on the same thing; the extra one is a "redundant article fork".
Here are some examples of pages of the same type on the same subject:
- An article about domestic house cats would be an unacceptable content fork of the existing article Cat (which is about domestic house cats).
- An outline of the People's Republic of China would be an unacceptable content fork of the existing Outline of China (which is about the People's Republic of China).
Creating such forks can be unintentional or intentional. Although Wikipedia contributors are reminded to check to make sure there is not an existing article on the subject before they start a new article, there is always the chance they will forget, or that they will search in good faith but fail to find an existing article, or simply flesh out a derivative article rather than the main article on a topic. If you suspect a redundant article fork, check with people who watch the respective articles and participate in talk page discussions to see if the fork was justified. If the content fork was unjustified, the more recent article should be merged into the main article.
Redundant content forks of page types other than articles are rarer, but they do occur.
Note that "redundant content fork" is an idiom, not to be taken literally. All content forks are redundant, that's their nature, even the acceptable ones, but we use the term "redundant content fork" to refer to the specific kind described in this section.
Point of view (POV) forks
editIn contrast POV forks generally arise when contributors disagree about the content of an article or other page. Instead of resolving that disagreement by consensus, another version of the article (or another article on the same subject) is created to be developed according to a particular point of view. This second article is known as a "POV fork" of the first, and is inconsistent with policy: all facts and major points of view on a certain subject should be treated in one article. As Wikipedia does not view article forking as an acceptable solution to disagreements between contributors, such forks may be merged, or nominated for deletion.
Since what qualifies as a "POV fork" can itself be based on a POV judgement, it may be best not to refer to the fork as "POV" except in extreme cases of persistent disruptive editing. Instead, apply Wikipedia's policy that requires a neutral point of view: regardless of the reasons for making the fork, it still must be titled and written in a neutral point of view. It could be that the fork was a good idea, but was approached without balance, or that its creators mistakenly claimed ownership over it.
The most blatant POV forks are those which insert consensus-dodging content under a title that should clearly be made a redirect to an existing article; in some cases, editors have converted existing redirects into content forks. However, a new article can be a POV fork even if its title is not a synonym of an existing article's title. For example, if an editor has tried to include in an existing article about aviation a theory that heavier-than-air flight is impossible, but the consensus of editors has rejected the attempt as complete nonsense, that fact does not justify creating an article named "Unanswered questions about heavier-than-air flight" to expound upon the rejected idea.
The creator of the new article may be sincerely convinced that there is so much information about a certain aspect of a subject that it justifies spinning off a separate article. Any subarticle that deals with opinions about the subject of parent article must include suitably-weighted positive and negative opinions, and/or rebuttals, if available, and the original article should contain a neutral summary of the split article. There is currently no consensus whether a "Criticism of..." article is always a POV fork, but many criticism articles nevertheless suffer from POV problems. If possible, refrain from using "criticism" and instead use neutral terms such as "perception" or "reception"; if the word "criticism" must be used, make sure that such criticism considers both the merits and faults, and is not entirely negative (consider what would happen if a "Praise of..." article was created instead).
