Manual:Interwiki table/ja

interwiki テーブルは、接頭辞とそのターゲットを保持します. 既定のインターウィキ接頭辞を参照してください. インターウィキ リンク自身は テーブルに格納されます.

iw_prefix
The prefix of the interwiki link; this is used the same way as a namespace is used when editing.

iw_url
The target of the link; the page name is substituted for $1.

iw_api
The URL of the file. This is not used except by, when an interwiki map is requested via.

iw_wikiid
The name of the database (for a connection to be established with )

iw_local
Informs MediaWiki how it should treat interwiki links coming from external sources. If iw_local is 1, then it will treat these links as though they were generated from within the local wiki.
 * For example, the interwiki link fr: on the en.wikipedia.org project has iw_local=1 set.

Therefore, the link to http://en.wikipedia.org/wiki/fr:Accueil gracefully redirects you to the French Homepage (Accueil). However, the WorldCat ISSN catalog is flagged 0 on en.wikipedia.org; the link to https://en.wikipedia.org/wiki/issn:1021-9749 does not work, even though 1021-9749 would work if it were on a local Wikipedia page. See m:Help:Interwiki linking#Non-local interwikis.

iw_trans
This is used to allow transcluding templates (or other pages) from another MediaWiki installation. Both  and   need to be on.
