The iwlinks table stores the interwiki links with their targets. Langlinks テーブルと混同しないでください。

フィールド

iwl_from

The page_id of the referring page (i.e. the local page that the link appears on).

iwl_prefix

interwiki prefix code of the target. This is used the same way as a namespace is used when editing.

iwl_title

The title of the target page, including namespace (FULLPAGENAME style). Spaces are converted to underscores, but the first letter is not automatically capitalized. So for example, an interwiki link to w:foo bar would have an iwl_title of "foo_bar".
