Semantic MediaWiki under Debian

Installing Semantic MediaWiki (SMW) under Debian

Installation consists of these simple steps:

1) Use Aptitude to install package mediawiki-semediawiki (under Lenny that's version 1.2-1)

2) Edit the file /etc/mediawiki-extensions/extensions-available/SemanticMediaWiki.php. All you need to do is change the string for enableSemantics from localhost to the hostname of your server:

<?php
include_once('extensions/SemanticMediaWiki/includes/SMW_Settings.php');
enableSemantics('dworkin.saruman.biz');
?>

Actually, the string for enableSemantics is an identifier, needed to identify any exported data. The Semantic MediaWiki website suggests using the server's host name for this purpose (if you have multiple hostnames, just pick any one of them).

3) We now run the maintenance script that sets up the MySQL database. This is a two-step affair: - first set the MW_INSTALL_PATH environment variable to the root of the MediaWiki installation. This path is where LocalSettings.php and index.php are located; most likely it's /usr/share/mediawiki.

MW_INSTALL_PATH=/usr/share/mediawiki
export $MW_INSTALL_PATH
cd /usr/share/mediawiki-semediawiki/maintenance

4) Adjust your namespaces - since we haven't modified the MediaWiki namespaces relative to the original Debian installation, we don't need that.

4) Setup the SMW tables in the MySQL database. To this end, we simply go to
