'''Interwiki links''' are links to pages of other projects, using a prefixed internal link style.

Interwiki links make it possible, to link to pages of (e.g.) Wikipedia, Wikibooks, Wikinews etc. or to your wiki-project in different languages (see [[Help:Wiki family]]).

A link like <code><nowiki>[[Wikipedia:Main Page]]</nowiki></code> will appear like this: [[Wikipedia:Main Page]] and redirect you to Wikipedia's Main Page.

For setting up interwiki links, you might need to edit the Database.

==Interwiki links to other projects==
===Default===
Several Wikimedia-Projects (and others) are ready for interwiki linking by default, so you can use them without editing your database:

===Adding more===
As the Wikipedia isn't set up by default, you might want to add it (and other projects of your need).

You have to edit your database.
Go to table <code>interwiki</code> and add a new line:
*'''<code>iw_prefix</code>''': choose a prefix, which is used for interwiki linking, e.g. "Wikipedia" or "wp" for linking to Wikipedia
*'''<code>iw_url</code>''': enter the project's URL, e.g. <code><nowiki>http://en.wikipedia.org/wiki/$1</nowiki></code> for Wikipedia. Don't forget the <code>$1</code> as it is replaced with the article's name you are linking to (<code><nowiki>[[Wikipedia:Main Page]]</nowiki></code> links to <code><nowiki>http://en.wikipedia.org/wiki/</nowiki>'''Main_Page'''</code>).
*'''<code>iw_local</code>''': ''(don't know what this is for)''
*'''<code>iw_trans</code>''': ''(don't know what this is for)''

==Interwiki links to other languages==
[[Image:M-en-interwiki lang.png|thumb|Interwiki links to other languages]]
If you have installed a [[Help:Wiki family|Wiki family]], you can link from an article in english to an article in german (if you have a german project, too). You can set up MediaWiki, to show those links in the sidebar, just below the toolbox.

In your filesystem, there is a subfolder of your MediaWiki installation, called "languages". Go there and have a look at "<code>Names.php</code>" as it contains a list of known languages and their prefixes. E.g. you want to add your german project, search "<code>Names.php</code>" for "Deutsch" and note the prefix "de".

If you know the "right" prefix, edit your database by adding a new line to table <code>interwiki</code>:
*'''<code>iw_prefix</code>''': language-prefix (e.g. "de" for german), which is listed in "<code>Names.php</code>"
*'''<code>iw_url</code>''': URL to your wiki-project (e.g. <code><nowiki>http://de.your-wiki.org/index.php/$1</nowiki></code>)
*'''<code>iw_local</code>''': ''(don't know what this is for)''
*'''<code>iw_trans</code>''': ''(don't know what this is for)''

Now, you can link an article to the same in other languages. Adding <code><nowiki>[[de:Hauptseite]]</nowiki></code> on your english Main_Page will create a link "Deutsch" below the toolbox, which leads to the Main_Page of the german wiki (Hauptseite).

Note, that this link is shown in Sidebar's section, '''only''', and not inside of the article. If you want to create a link inside of the text, you have to add a colon previous to the prefix: <code><nowiki>[[:de:Hauptseite]]</nowiki></code>.
