Interwiki 扩展将"Special:Interwiki"页面添加到 MediaWiki ，以查看和编辑 interwiki 表，以及使用它所做的任何操作的日志。

It was merged into MediaWiki core in MediaWiki 1.44.

它适用于 $wgInterwikiCache 变量。 与之相关的跨wiki表更改会影响transclusion 和interwiki links 的行为。

"Special:Interwiki" 的列表与 API api.php?action=query&meta =siteinfo&siprop=interwikimap 相同，只是 iw_api 字段不可用。

安裝

• 下载文件，并将解压后的Interwiki文件夹移动到extensions/目录中。
  开发者和代码贡献人员应从Git安装扩展，输入：cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/Interwiki
• 将下列代码放置在您的LocalSettings.php 的底部：

  wfLoadExtension( 'Interwiki' );
  // 授予管理员权限以编辑跨维基数据
  $wgGroupPermissions['sysop']['interwiki'] = true;
  

•  完成 – 在您的wiki上导航至Special:Version，以验证已成功安装扩展。

• MediaWiki 自带的配置不会授予任何用户组权限。 因此，您需要自己添加配置，否则没有人能够编辑跨维基数据。
• 要启用来自其他站点的嵌入，您需要启用 $wgEnableScaryTranscluding 。
• 要禁用通过 Special:Interwiki 接口添加前缀，请将 $wgInterwikiViewOnly 设置为 true。

这个扩展在特殊页面列表中的条目不是扩展的名称。 列表中的条目由 SpecialInterwiki.i18n.php 中每个语言环境定义的 interwiki 消息项定义。 它的值为查看和编辑跨wiki数据。

配置跨语言链接

To set up interlanguage links using this extension, make sure that $wgInterwikiMagic is set to true and $wgHideInterlanguageLinks is set to false (they are like this by default, you don't need to change them usually). The $wgInterwikiViewOnly also needs to be set to false (which it is by default). Then go to Special:Interwiki as a user with the ability to edit interwikis. That is controlled by the interwiki permission, and by default, no user group has this permission, so it needs to be added to a user group with, e.g.

$wgGroupPermissions['sysop']['interwiki'] = true;

Once on Special:Interwiki, you can either click the "Add an interwiki or language prefix" link at the top of the table, or click the "Edit" or "Delete" links in the table row of an existing interwiki prefix.

Choosing to add or edit an interwiki prefix will take you to a separate page with a form with various fields to be filled. The main fields are "name", which is the prefix that would be used for the links, and "URL", where you put the full URL pattern. For example, setting name=foowiki and URL=http://fr.foowiki.tld/wiki/$1 would make [[foowiki:Blah]] point to http://fr.foowiki.tld/wiki/Blah.

There are also two checkboxes labeled "Forward" and "Transclude". See Manual:Interwiki table for a full explanation of the forward (iw_local) and transclude (iw_trans) bits.

In brief:

• Enabling forwarding ('local' true) is normally done between all languages and projects in the same group, as it allows a link to any one of the languages to be used as a gateway to the others. The English-language Wikipedia, for instance, sets the 'local' bit true for all of the other-language Wikipedias and for projects like commons:, wikinews: or wikivoyage:. A user on a wiki outside Wikipedia where the wikipedia: interwiki prefix points to en.wikipedia.org could create a link like wikipedia:fr:Encyclopédie. That link goes initially to "fr:Encyclopédie" on the English-language Wikipedia. The en.wikipedia server immediately recognises fr: as a 'local' interwiki link, so replies with a redirect to la Wikipédia where fr.wikipedia.org/wiki/Encyclopédie displays the requested French-language Wikipédia page [[Encyclopédie]] et voilà.
• Enabling transclusion is rarely done, as it allows an article on one wiki to use templates from some other wiki. This is referred to as 'scary transclusion' as it will cause problems if the other wiki changes the template unexpectedly. A few wiki farms use this to create one 'central wiki' with various templates which are made available to other wikis in the same farm. If you don't need this, don't enable it.

全域跨维基

Since version 3, Interwiki supports defining a global/central database and pulling defined interwikis from there as well as from the local table. This functions essentially as a table merge, with local interwiki definitions overriding central. Language links are not pulled from the central table; these are set up as local-only due to a central table likely serving more than one project (with each having its own languages).

The central table is the interwiki table of the central wiki. This means that as far as the central wiki is concerned, it is basically just a normal non-global setup. There are therefore no special rights associated with the central (global) table, though it is likely you may want to be more picky about how you assign the 'interwiki' edit right on this wiki.

• This was decided by looking at current possible use cases (ShoutWiki's hub, Uncyclomedia's central wiki, and Meta-Wiki) where the central wiki isn't going to have anything extra anyway.
• This might change in the future, but anything more intelligent will require schema updates.
• This probably doesn't work with table prefixes because of how the table is accessed.

To set up a central interwiki table, simply provide the name of the database of the wiki you want to use:

// Enable pulling global interwikis from a central database
$wgInterwikiCentralDB = 'mw_central';

Replace 'mw_central' with the name of the database.

For those using table prefixes here is an alternative solution for "pool_example_wiki" tables.

$wgSharedDB = 'example_wiki'; # The $wgDBname for the wiki database holding the main interwiki table
$wgSharedPrefix = 'pool_'; # The $wgDBprefix for the database. Defaults to the prefix of the current wiki if not specified
$wgSharedTables = ['interwiki'];

协议相对 URL

You can use protocol-relative URLs (PRURLs), so that users accessing your wiki over either HTTP or HTTPS can use that same protocol to access interwiki links. To use a PRURL, first ensure the destination server supports HTTPS; if it does, then simply remove the https: portion of the URL in the link table. For example, change

https://en.wikipedia.org/wiki/$1

to:

//en.wikipedia.org/wiki/$1
