The interwiki table stores the interwiki prefixes with their targets.

- iw_prefix is the prefix of the interwiki link; this is used the same way as a namespace is used when editing.
- iw_url is the target of the link; the page name is substituted for $1.
- iw_api is the URL of the file api.php
- iw_wikiid is the name of the database (for a connection to be established with wfGetLB( 'wikiid' ))
- 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 Wikimedia foundation project site is flagged 0 on en.wikipedia.org; the link to http://en.wikipedia.org/wiki/wikimedia:Home does not work, even though [[wikimedia:Home]] would work if it were on a local Wikipedia page.
- iw_trans: is used to allow transcluding templates (or other pages) from another MediaWiki installation. Both
$wgEnableScaryTranscluding and iw_trans need to be on.
