The Semantic Genealogy extension provides the ability to view genealogy trees and export GEDCOM files.


Having MediaWiki (version 1.23 or higher), Semantic MediaWiki (version 1.7 or higher) installed is a precondition for the Semantic Genealogy extension. The code will not work without them.

  • Download and move the extracted SemanticGenealogy folder to your extensions/ directory.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/SemanticGenealogy
  • Add the following code at the bottom of your LocalSettings.php file:
    require_once "$IP/extensions/SemanticGenealogy/SemanticGenealogy.php";
  • Configure as required.
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.



In your "LocalSettings.php" add e.g. the following statement after the inclusion of this extension:

$wgGenealogicalProperties = [
	'givenname' => 'Vorname',
	'surname' => 'Nachname',
	'nickname' => 'Kosename',
	'sex' => 'Geschlecht',
	'birthdate' => 'GebDatum',
	'birthplace' => 'GebOrt',
	'deathdate' => 'TodDatum',
	'deathplace' => 'TodOrt',
	'father' => 'Vater',
	'mother' => 'Mutter'

Replace the field values with the appropriate field names in your wiki. (The keywords in the second column probably need to be capitalized, so as to match the properties view of the pages.) The most importing obviously is to define the 'father' and 'mother' relationships correctly.



Go to special page "Special:FamilyTree", select a person and display either a tree of ancestors or descendants or a relationship to another person.
