which have content with a similar purpose, i.e. pages where the intended use is the same. Namespaces can be thought of as partitions of different types of information within the same wiki, and keep "real" content separate from <a href="/wiki/Special:PrefixIndex/User:" title="Special:PrefixIndex/User:">user profiles</a>, <a href="/wiki/Special:PrefixIndex/Help:" title="Special:PrefixIndex/Help:">help pages</a>, etc. The namespace <b>prefix</b> of a page forms part of the title of a page, separated with a <b>colon (<code>:</code>)</b>. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Technical_overview">Technical overview</h2></div> <p>As said, pages exist within a namespace, and this can be distinguished using the namespace prefix of a page, which forms part of the title of a page, separated with a colon (<code>:</code>). </p><p>For example: </p> <table class="wikitable"> <tbody><tr> <th>Title</th> <th>Namespace </th> <th>Code </th></tr> <tr> <td><code>Foo</code></td> <td>Main </td> <td>0 </td></tr> <tr> <td><code>Template:Foo</code></td> <td>Template </td> <td>10 </td></tr> <tr> <td><code>Module:Foo</code></td> <td>Module </td> <td>828 </td></tr></tbody></table> <p>The "main namespace" does not have a prefix. Also, pages in the main namespace cannot have names starting with any of the existing namespaces prefixes followed by a colon. </p><p>Pages can be <a href="/wiki/Special:MyLanguage/Help:Moving_a_page" title="Special:MyLanguage/Help:Moving a page">moved</a> between namespaces simply by changing the prefix part of their title. </p><p>Namespace prefixes can be translated, and aliases (helpful in shortcuts) can be configured for each (see <code><a href="/wiki/Special:MyLanguage/Manual:$wgNamespaceAliases" title="Special:MyLanguage/Manual:$wgNamespaceAliases">$wgNamespaceAliases</a><span style="display:none"><a href="/wiki/Manual:$wgNamespaceAliases" title="Manual:$wgNamespaceAliases"> </a></span></code>). All namespaces also have a "canonical" prefix, which works on all wikis regardless of configuration. Aliases and canonical names can be used in links, when performing a <a href="/wiki/Special:MyLanguage/Help:Searching" title="Special:MyLanguage/Help:Searching">search</a>, and in the page title with the help of the {{DISPLAYTITLE}} <a href="/wiki/Special:MyLanguage/Help:Magic_words" title="Special:MyLanguage/Help:Magic words">magic word</a>. </p><p>Each namespace has a corresponding <b>namespace index</b>. Within the database, the title is split into namespace index and text title, and this is used for storage in the <code>page.page_namespace</code> and <code>page.page_title</code> columns, among others. </p> <div class="mw-heading mw-heading3"><h3 id="Subject_and_talk_namespaces">Subject and talk namespaces</h3></div> <dl><dd><i>See <a href="/wiki/Special:MyLanguage/Help:Talk_pages" title="Special:MyLanguage/Help:Talk pages">Help:Talk pages</a><span style="display:none"><a href="/wiki/Help:Talk_pages" title="Help:Talk pages"> </a></span> for instructions on how to use talk pages.</i></dd></dl> <p>Most namespaces have an associated <b>discussion namespace</b> (or "talk" namespace).
