Manual:Iwlinks table

The iwlinks table stores the interwiki links with their targets. Not to confuse with the Langlinks table.

iwl_from
The  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 (FULLPAGENAMEE style).
