Special:RandomPage – brings the user to a random page in the wiki.The Subcategory of property is a special property in Semantic MediaWiki with a built-in meaning: it is used to indicate that a category is a subcategory of another and that SMW should treat this subcategory as a subclass for the purpose of inferencing in queries.Special:AllPages – shows all non-special pages in the wiki, subdivided by namespace Special:SpecialPages – shows the set of all special pages on the wiki this is a useful starting point (although see here for the Admin Links extension, which provides an alternate approach) Special:Version – shows the current version of MediaWiki, as well as of any extensions that are installed Special:Watchlist – shows the most recent change to any page that the current user is "watching" (see here).Special:Contributions – shows the set of edits made by any one user (when the page is called in the form "Special:Contributions/username") Special:RecentChanges – shows the list of recent edits in the wiki (see here) Among the special pages defined in core MediaWiki are: MediaWiki defines a wide variety of special pages, as do many MediaWiki extensions. Instead, the content of these pages is defined by the PHP code. They are contained in the namespace "Special:", and unlike other pages, they can't be edited, they have no page history, and they don't have an associated talk page. There are pages in MediaWiki that do not contain editable content, but rather interface elements, like lists and helper forms. It requires knowledge of database manipulation, and is not recommended unless you really know what you're doing. The third involves going into the database, finding the entry for the page in the 'page' table, and changing both the namespace and the page name via SQL or some other tool. The second way is to call the script "namespaceDupes.php", available in MediaWiki's /maintenance directory. How can you recover the page that was created before? There are three ways: the first, and probably easiest, way is to temporarily unset the "City" namespace, then move the page "City:Brussels" to any name that doesn't start with "City", then reinstate the "City" namespace, and move the page back to the name "City:Brussels". You do that, and then you discover that the page "City:Brussels" is blank again! That's because the page you created was "City:Brussels" in the main namespace, whereas the page you're going to now is "Brussels" in the "City" namespace. Let's say you create a page called "City:Brussels", and then remember that you haven't yet created a "City" namespace. The way namespaces are structured can lead to one potential awkwardness. System messages and wiki-wide CSS and JS content "Project talk" and a specific name + " talk" "Project" and a specific name for that wiki, usually the name of the wiki Used for special pages defined by the softwareĭiscussions about pages in the main namespace Used for directly linking to uploaded files
