Manual:Contents MediaWiki database layout interwiki table


Contents

The interwiki table stores the interwiki prefixes with their targets. See default interwiki prefixes. The interwiki links themselves are stored in the iwlinks table. This data can be accessed using the Interwiki class.

FieldsEdit

iw_prefixEdit

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

iw_urlEdit

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

iw_apiEdit

MediaWiki version: 1.17

The URL of the file api.php . This is not used except by ApiQuerySiteinfo::appendInterwikiMap(), when an interwiki map is requested via siprop=interwikimap .

iw_wikiidEdit

The name of the database (for a connection to be established with wfGetLB( 'wikiid' ))

iw_localEdit

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 [[issn:1021-9749]] would work if it were on a local Wikipedia page. See m:Help:Interwiki linking#Non-local interwikis.

iw_transEdit

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