Help:Interwiki

The Interwiki extension introduces interwiki links to MediaWiki, allowing the usage of prefixes in internal links to link to websites outside your wiki. The extension is pre-installed with MediaWiki, i.e. you do not need to manually enable it. Interwiki links provide a simple and efficient method for repeatedly linking to specific other websites, and are displayed like normal internal links&lsqb;note 1&rsqb;.

How to use
In the above example, w is assigned to link to English Wikipedia. You can find the full list of interwiki prefixes on the Special:Interwiki special page on each wiki.

Linking to other WikiTide wikis
Linking between WikiTide wikis can be done with [ [wt:subdomain:pagename]], which brings you to the pagename page on subdomain.wikitide.com, e.g.  wt:meta:Help:Interwiki  will link to this page (Help:Interwiki) on WikiTide Meta (meta.wikitide.com) from other WikiTide wikis.

Scary transclusion
Scary transclusion is enabled if the  option is enabled on the interwiki table while $wgEnableScaryTranscluding is enabled (in Special:ManageWiki/settings).

Managing interwiki entries
By default, bureaucrats of WikiTide wikis can manage their wiki's interwiki table via the Special:Interwiki page. This section will guide you through the setup for interwiki entires.

Before you move on
You should check the following before adding a link to your interwiki table:
 * Does your preferred prefix overlap with a global prefix? : Please check the "" table to see if a prefix is already taken by a global prefix. It is generally understandable for non-English wikis to overwrite prefixes that point to English Wikipedia (i.e. w:, wp: and wikipedia:) with other language versions of Wikipedia for convenience, but prefixes pointing to other WikiTide subdomains (e.g. m:</tt>, wt</tt> and meta</tt>) should never be overridden.
 * Does your preferred prefix overlap with an existing local prefix? : If so, you will have to choose another prefix as interwiki prefixes must be unique.
 * Is your preferred prefix inappropriate? : use prefixes that contain sexual content, profanity, discrimination or any other inappropriate content. Content violating the Content Policy or Terms of Use may be removed, and sanctions may be placed on users introducing such content.
 * Is the destination URL safe and live?
 * Please the URL you are redirecting to does not resolve into malicious links.  Tools to assist checking include URLVoid, VirusTotal, Google Transparency Report.

Using the interface
You can first navigate to Special:Interwiki on their wiki and review existing interwiki tables. Existing interwiki prefixes are listed in two sections: for the default set available across WikiTide, and  for the set that exists locally, added previously.

You can then use the "Special:Interwiki/add" link to open the Special:Interwiki/add interface, where there will be six fields to fill in:
 *  Input the preferred prefix without the colon .
 * : Links with this prefix will be redirected to the target URL if checked, e.g.  https://meta.wikitide.com/wiki/w:Help:Interwiki </tt> will redirect you to  https://en.wikipedia.org/wiki/Help:Interwiki </tt>; a "" error will be given if trying to navigate with the same link but with this box unchecked.
 * : Allows scary transclusion if $wgEnableScaryTranscluding is also enabled (in Special:ManageWiki/settings). This means you can transclude a page or template from another wiki with this option enabled via { {prefix:templatename}}</tt>. For example if w</tt> has transclusion enabled, { {w:1x}}</tt> will transclude w:Template:1x; to transclude pages outside the Template: namespace, put an extra colon after the prefix, e.g. { {w::Article}}</tt> will transclude Article, and { {w::Help:Interwiki}}</tt> will transclude w:Help:Interwiki.
 *  Input the URL of the target website. The URL should contain a dynamic variable for the destination page name formatted as $1</tt>, e.g.  https://en.wikipedia.org/wiki/$1 </tt>. It also should not include trailing spaces – ensure that you are not copying any extra spaces when adding the interwiki prefix.
 *  This field should generally be left blank.
 *  (Optional) The reason for adding the interwiki prefix, will be included in the at Special:Log/interwiki.

After everything has been entered correctly, click the button to submit the addition. You will be redirected back to the interwiki table, where you should confirm that the entry shows up correctly. If your entry shows up under the section and is not intended as such, a different prefix should be selected, as interlanguage links behave differently from interwiki links.
