Wikipedia:Wikimedia sister projects
 |
This page documents an English Wikipedia style guideline. It is a generally accepted standard that editors should attempt to follow, though it is best treated with common sense, and occasional exceptions may apply. Any substantive edit to this page should reflect consensus. When in doubt, discuss first on the talk page. |
Wikimedia sister projects are all the publicly available wikis operated by the Wikimedia Foundation, including Wikipedia. This guideline covers Wikipedia's relations to the sister projects, including linking and copying content between Wikipedia article and a sister project.

The above list of the current English language sister projects can be easily duplicated using the {{Wikipedia's sister projects}} template.
When to link
Wikipedia encourages links from Wikipedia articles to pages on sister projects when such links are likely to be useful to our readers, and interlingual crosslinking to articles on foreign-language editions of Wikipedia whenever such links are possible.
By far, the most common use of links to the non-Wikipedia sister projects is the use of images that are stored on the Wikimedia Commons site (see Wikipedia:Wikimedia Commons).
How to link
 |
Wikisource has original text related to this article: |
Links to sister projects are made in several ways:
- by linking images and other files hosted by Commons. See Wikipedia:Picture tutorial for more;
- through inline links such as this link to The Wind in the Willows;
- through templates, which may produce either larger boxes or simpler one-line links. See the next section for how and where to place them; Templates are found in Wikipedia:Template messages/Sister projects and Category:Interwiki link templates;
- through standard links directly to the URL, exactly like any other website, such as The Wind in the Willows.
Where to place links
Sister project links should generally appear in the "External links" section, not under See also. Two exceptions are Wiktionary and Wikisource links that may even be linked inline, like the last word "inline", i.e. as the text of a document that might not be familiar to all readers.

Wikimedia Commons has media related to Wikipedia logos. |
More precisely, box-type templates such as {{Commons}} shown at right have to be put at the beginning of the last section of the article (which is not necessarily the "External links" section) so that boxes will appear next to, rather than below, the list items. Do not make a section whose sole content is box-type templates. Many box links can be unified to one by using {{Sister project links}}.
Sometimes box-type templates are not good, either because there are no external links except sister project ones, or because they result an odd layout, such as a long sequence of right-aligned boxes hanging off the bottom of the article or excessive white space when the section is laid out in columns. In such cases, consider using "inline" templates, such as {{Commons-inline}} in the "External link" section, so that links to sister projects appear as list items, like this:

Media related to As with standard links to other Wikipedia articles, same sister project links are normally made only once within an article.
Soft redirects from Wikipedia to a sister project
Sometimes an entry is more appropriate on Wiktionary than Wikipedia and can never be expanded beyond simple dictionary definition. Normally, such articles are copied to Wiktionary using transwiki process, and deleted from Wikipedia afterwards.
However, if the word or phrase is commonly wikified, it is quite likely that the deleted entry will be quickly re-created again by well-meaning users. The re-created article is likely to be another simple dictionary definition, just as inappropriate for Wikipedia as the original.
To avoid this, do not delete after transwiki'ing. One solution, as suggested by Wikipedia deletion policy, is to instead normally redirect the word to a relevant article within Wikipedia. For instance, Organize could redirect it to a well-developed Organization article via #REDIRECT [[Organization]].
If this is not possible, turn a Wikipedia page into a soft redirect to a sister project. This is done by replacing the page with either the {{softredirect}} template, or one of specialized templates (template {{wi}} is recommended in case of Wiktionary). These templates inform reader to look for information on the sister project, in case of this example provide link to wikt:Organize article. This has multiple benefits:
- it brings the sister projects closer together,
- it prevents future clean up issues.
Wikipedia does not have an article with this exact name. Please search for Wikimedia sister projects in Wikipedia to check for alternative titles or spellings.

This applies to other sister projects as well, not only to Wiktionary. Please keep in mind that only commonly wikified words should become soft redirects. We don't need a soft redirect for every possible word or phrase to be included in Wikipedia.

Unified login or Merged Account
Unified login is a mechanism which allows users to use a single login across the majority of the Wikimedia Foundation's sister projects. This allows users to maintain a consistent identity throughout Wikimedia, following a single sign-up. Other advantages of this mechanism include the removal of the threat that impersonation poses and the ability to visit many projects without having to go through the labors of logging in everywhere. Users can create a unified login by visiting Special:MergeAccount on a project where they already have an account, and following the prompts.
