Pagelinks.sql.gz
Pagelinks.sql.gz - file from Wikipedia dumps, which contains wiki page-to-page link records. Tracks all internal links in the Wiki. Each entry contains the source page's ID and namespace (number), and the article name (in text) and namespace (number) that is being linked to from within that source page. There may be many instances of the source page's ID, as many as the internal links within it, but there can be only one entry per internal link for any page ID.
