Pages on the English Wikipedia that start with any of the following prefixes are *not* in the main namespace (ns0): Talk: User: User talk: Wikipedia: Wikipedia talk: File: File talk: MediaWiki: MediaWiki talk: Template: Template talk: Help: Help talk: Category: Category talk: Portal: Portal talk: Special: All pages that do not start with one of these special prefixes are automatically in namespace 0. To check the namespace number of a page if you're uncertain, you can view the page source and check the body element's classes. namespace 0 pages will have the class "ns-0". Other pages will have some other number; for instance, "Talk:" pages will have "ns-1", because "Talk:" is namespace 1. "User:" is 2, "User talk:" is 3, etc. ___ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l

Immense amounts of text that no one can maintain (are interested in maintain) and let on his own suffer a continuous degradation.

The terminology is indeed confusing. ns0 is the "main" namespace, which is used for "articles". But it also contains redirects. For the statistics, the software tries to count "real" or "good" articles, which is defined to be in ns0, not a redirect, and containing at least one link. It may in the future even be redefined not to include disambiguation pages. The title list however contains all pages in ns0. Talk pages are in their own namesapace, or rather, namespaces. Namespaces come in pairs: the namespace itself (even id), and the corresponding talk namespace (odd id). -- daniel ___ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l

The description for pages-articles.xml.bz2 says it contains "Articles, templates, image descriptions, and primary meta-pages." all-titles-in-ns0.gz contains (as the name suggests) only the titles in ns0, i.e., the main namespace, articles.
