+== About ==
+
+''SemanticUpdateOnPurge'' is a MediaWiki extension by Daniel Werner which
updates Semantic MediaWikis properties
+of an article whenever the article is purged.
+SMW standard behavior is to update properties only on page save (as of SMW 1.6)
+
+
+== Installation ==
+
+Once you have downloaded the code, place the 'SemanticUpdateOnPurge' directory
within your MediaWiki 'extensions'
+directory. Then add the following code to your
[[Manual:LocalSettings.php|LocalSettings.php]] file:
+
+ # SemanticUpdateOnPurge
+ require_once(
"$IP/extensions/SemanticUpdateOnPurge/SemanticUpdateOnPurge.php" );
+
+
+== Compatibility ==
+
+Version 0.2.1 to 0.4 are tested on SMW 1.6.1 and 1.6.2 (propably working with
1.6 too) There have been some issues
+with some versions of the SMW 1.5.x branch, where in early versions the
extension seemed to work, then it didn't.
+
+
+== Contributing ==
+
+If you have bug reports or requests, please add them to the
''SemanticUpdateOnPurge'' Talk page [0].
+You can also send them to Daniel Werner < [email protected] >
