Extension:Semantic Genealogy

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

Customization
In your LocalSettings.php add e.g. the following statement at the end:

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.

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