Through the following set of Wikisphere extensions you can:

  • assign pages and sub-pages to specific users, specific groups or any combination of the two, with specific roles and permissions, through a user-friendly control panel
  • enforce an implicit moderation on your wiki. You don't directly moderate pages (or page versions) as in FlaggedRevs or Approved Revs, instead, you assign a page and its sub-pages to authorized user(s) or group(s) which can edit their properties. When the page is ready for publishing, either you publish it as moderator, or you provide the page creator with the relevant permission (i.e., you assign the page to that user or to a group to which the user belongs)
  • easily set an empty title for pages, without having to resort in solutions like this one
  • easily assign display title, language, content model, published status (as semantic property), and SEO metadata to each page and its sub-pages
  • easily create pages with pre-loaded content through regular expressions
  • assign an user to a page for a given period, e.g. until your team members are affiliated to your organization
  • upload pictures under the current page, letting you to don't worry about the picture's title and even duplicates ! (inasmuch as the picture is thus characterized by its path)
  • ... (to be completed)


(each module is technically an autonomous extension)

name description required extensions
Wikisphere common Common methods required from the various Wikisphere extensions Semantic Mediawiki/PageForms
Wikisphere PageProperties Allows to easily edit display title, language, content model of a page and its published state. Provides support for SEO metadata Wikisphere common
Wikisphere PageOwnership Provides support for page ownership and attribution Wikisphere common
Wikisphere Subpages Provides a list of sub-pages on the navigation panel, a magic word to display sub-pages of a given page, and a special page to navigate through sub-pages none
Wikisphere FileInclusion A simple extension to display the content of authorized files within pages SyntaxHighlight (optionally)

Wikisphere is also featuring a set of patches specifically allowing the upload of files at a specific path, an enhanced management of sub-pages and many improvements to popular extensions (primarily PageForms).

Configuration variables

variable possible values description
$wgWikisphereHandleDraftState none, new, all, owned requires the extension Wikisphere PageProperties. If set to "none" the pages don't need to be explicitly published through the page Properties (reachable from the dropdown of page actions, see picture ...) in order to be accessible to everybody. If set to "new" only new pages need to be explicitly published to be accessible to everybody. If set to "owned" only owned pages and sub-pages need to be published in order to be accessible to everybody or to be posted on the global database (front-end)
$wgWikisphereOnBoardCreateOwnedPages object if the extension Wikisphere PageOwnership is installed, automatically creates "on board" owned pages with given roles and permissions as defined in an object like
$wgWikisphereOnBoardCreateOwnedPages = [
		'page_name' => '{{realname_or_username}}',
		'role' => 'editor',
		'permissions' => 'edit,create,subpages',
		'template' => "Personal_page_name"


$wgWikisphereUploadDisableWarnings true/false disables "was-deleted", "duplicate", "duplicate-archive" and "bad-prefix" warnings on file upload (requires the patches in the file includes/upload/UploadBase.php)
$wgWikisphereUploadUnderCurrentPage true/false currently used in PageForms, input with "uploadable" parameter: if set to true the picture will be uploaded under the current page, so that the filename of the picture will be [title of current page]/[picture filename]

This allows the use of generic names, which are by contrast characterized by their path.

This feature requires the patches described here and it also works with the "one-step process" using page name formulas (the picture is uploaded in a temporary path and then moved to the page newly created)

It does also exist a patch for MsUpload (currently not used, in favor of VisualEditor enabled by default also for wikitext)

$wgWikispherePreloadContent object On page creation, automatically creates one or more pages associated to the matched regular expression:
$wgWikispherePreloadContent = [


		// can be a regular expression
		// 1638769189/News_articles/2021/12/article_test
		'match' => '#^([^/]+)/(News articles|News digests)/([^/]+)/([^/]+)/([^/]+)$#',
		'pages' => [			
				'page' => '$1/$2',
				'template' => "Subpages list"
				'page' => '$1/$2/$3',
				'template' => "Subpages list"



$wgWikispherePostOnWikisphere true/false posts the semantic content on the global database (front-end)

Once installed, the extension Wikisphere PageOwnership prevents standard users to edit pages to which they have not been assigned (individually, or as a group).

new groups
name description
Unassigned pages editor (wikisphere-regularpageseditors) members of this group can edit unassigned pages (pages without owners)
Moderator (wikisphere-moderator) members of this group can insert other users in the group "Unassigned pages editor"

new rights
right description
wikisphere-editregularpages allows to edit unassigned pages (pages without an owner)

To further restrict editing of system namespaces you can use $wgNamespaceProtection

// restrict editing
$wgNamespaceProtection[NS_PROJECT]  = 
$wgNamespaceProtection[NS_TEMPLATE] = 
$wgNamespaceProtection[NS_CATEGORY] = 
$wgNamespaceProtection[NS_MODULE]  =
$wgNamespaceProtection[PF_NS_FORM]  =
$wgNamespaceProtection[NS_MEDIAWIKI]  =
// if restricted new users cannot create an account
//$wgNamespaceProtection[NS_SPECIAL]  = 


To allow users or groups to edit regular pages you can use the right "wikisphere-editregularpages" mentioned above, for instance using

$wgGroupPermissions['*']['wikisphere-editregularpages'] = false:
$wgGroupPermissions['user']['wikisphere-editregularpages'] = false;

custom semantic properties
property description
wikisphere published (__wikisphere_published) marks a page as published (through the Page properties control panel)
