Extension:Semantic Title

The SemanticTitle extension sets visible page title to a value of semantic property.

For example, if page `Bug:32758' has semantic property `Title' with value `SMW handles timezones incorrectly', and SemanticTitle is properly installed and configured, visible page title will be `SMW handles timezones incorrectly', with subtitle `Bug:32758'.

Similarly, link to the page will be `SMW handles timezones incorrectly' with tooltip `Bug:32758'.

returns `SMW handles timezones incorrectly' as plain text (not a link).

Rationale
Let us assume we are creating a bug tracking system based on MediaWiki. Semantic MediaWiki converts wiki into a database. Pages become objects or entities (e. g. bugs) with properties (e. g. title, submitter, severity, component, etc). We want every bug is identified by its number, assigned automatically. Semantic Forms allows it:

...

so every new bug receives unique identifier. Everything works, but bug page title will be `Bug:32758', links to this bug will also be `Bug:32758', while we want to see bug titles (set by user, not an id assigned by system) in page titles and links. This is the job for SemanticTitle extension.

Installation
This extension requires Semantic MediaWiki to be installed first.

If this extension is used with the HidePrefix extension, SemanticTitle should be included before HidePrefix (SemanticTitle does not touch title if it was set to non-default value, e. g. processed by HidePrefix extension).

Configuration
In LocalSettings.php after including `SemanticTitle.php':

where:


 * NS# — Namespace index (not a namespace name!) (usually constant, like ). Only pages in specified namespaces are affected.
 * Property name# — Name of property to be used as title in the specified namespace.

You may also optionally set  to "true" to hide the subtitle that shows the "real" page title.

Usage
Being installed and configured, SemanticTitle handles page titles and links with no user intervention.

However, category listings may look ugly, because listings show semantic titles while pages are sorted in order of their actual titles. Use  magic word to fix it, e. g.:

Title::title

If you need semantic title of a page as plain text (not a link), use  parser function:

Other extensions can call ` ' static function to get a semantic title by given title.

Version 2.1

 * Added SemanticTitle:getText and API interface.

Version 2.0

 * Talk pages that have a semantic title for the associated subject page have their titles displayed with that semantic title. The display of the talk page title can be customized with the message "semantictitle-talkpagetitle".
 * Fixed character encoding bug.
 * Coding style modifications.

Version 1.3

 * Fixed bug that caused the page title not to be transformed on pages that use the LiquidThreads extension. This may also have affected other pages with title fragments.

Version 1.2

 * Added support for the SelfLinkBegin hook (Linker.php in MediaWiki core). This replaces self links on a page with the semantic title text as the link text.

Version 1.1.0

 * Remediated XSS vulnerability CVE-2014-2854.
 * Migrated to JSON i18n. Beginning with MediaWiki 1.23, translation strings are stored in JSON files, and the EXTENSION.i18n.php file only exists to provide compatibility with older releases of MediaWiki. For more information about this migration, see: https://www.mediawiki.org/wiki/Requests_for_comment/Localisation_format.

Caveats

 * SematicTitle overrides edit page title set by Semantic Forms (specified by ` ' construct).
