Semantic MediaWiki

Install

1. First, install composer :

curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer

2. Run the installation scriptfrom the base directory of your MediaWiki installation:

cd /var/www/html/wiki
composer require mediawiki/semantic-media-wiki "~2.1"

3. Run the setup script from the base directory of your MediaWiki installation:

php maintenance/update.php

4. Add a call to enableSemantics() to the end of the "LocalSettings.php" file. enableSemantics() takes in the domain name of the wiki; a wiki located at "example.org", for instance, should have the following call:

nano /var/www/html/wiki/LocalSettings.php
enableSemantics( 'tacticaltech.org/wikigti' );

Update

Use these instructions to update an existing SMW installation.

  1. Backup your database and installation.
  2. Run the update script from the base directory[1] of your MediaWiki installation:[2]
    php composer.phar update
  3. See the page "Special:Version" on your wiki to verify that the extension was successfully updated.
  4. Run the setup script from the base directory[1] of your MediaWiki installation:
    php maintenance/update.php
  5. Run the refresh database script from the base directory[1] of your MediaWiki installation:[3]
    php extensions/SemanticMediaWiki/maintenance/SMW_refreshData.php -d 50 -v
  6. Done!

Update database tables

Command line

In the directory where your LocalSettings.php is located, run the following command:

php maintenance/update.php

Web browser

Go to example.com/mediawiki/mw-config/ by using your domain and path and rerun install.

Configuring LocalisationUpdate

If you are on unix-like system, you should add LocalisationUpdate to crontab:

crontab -e
# Add the following line
@daily php /path/to/your/wiki/extensions/LocalisationUpdate/update.php --quiet

VisualEditor

Dependencies

VisualEditor depends on the following extension:

To install it, do as root :

gpg --keyserver keys.gnupg.net --recv-keys 5C927F7C
gpg -a --export 5C927F7C | apt-key add -
nano /etc/apt/sources.list file

Add the parsoid repository to your /etc/apt/sources.list file

deb [arch=amd64] http://parsoid.wmflabs.org:8080/deb wmf-production main

To install,

sudo apt-get update && sudo apt-get install parsoid
nano /etc/mediawiki/parsoid/settings.js

Open the config file in /etc/mediawiki/parsoid/settings.js and update it to reflect your API URL

parsoidConfig.setInterwiki( 'localhost', 'http://localhost/wiki/api.php' );

Installation

the git version is for mediawiki 1.25

wget https://extdist.wmflabs.org/dist/extensions/VisualEditor-REL1_24-af11aa1.tar.gz
tar -xzf VisualEditor-REL1_24-af11aa1.tar.gz -C /var/www/html/wiki/extensions
rm VisualEditor-REL1_24-af11aa1.tar.gz

Add the following lines to your wiki's LocalSettings.php after you have downloaded the extension:

# VisualEditor http://www.mediawiki.org/wiki/Extension:VisualEditor
require_once "$IP/extensions/VisualEditor/VisualEditor.php";
// Enable by default for everybody
$wgDefaultUserOptions['visualeditor-enable'] = 1;
// Don't allow users to disable it
$wgHiddenPrefs[] = 'visualeditor-enable';
// OPTIONAL: Enable VisualEditor's experimental code features
#$wgDefaultUserOptions['visualeditor-enable-experimental'] = 1;

To get VisualEditor to talk to Parsoid, add the following code to your LocalSettings.php to specify your Parsoid instance:

// URL to the Parsoid instance
// MUST NOT end in a slash due to Parsoid bug
// Use port 8142 if you use the Debian package
$wgVisualEditorParsoidURL = 'http://localhost:8142';

/!\ Restart nodejs after install /!\

/etc/init.d/parsoid restart


MwEmbed

git clone https://github.com/kaltura/mwEmbed.git
mkdir cache
chown www-data:www-data cache/
# MwEmbed https://github.com/kaltura/mwEmbed
// Auth testing sets
$wgKalturaAuthHTTPS = false;
$wgKalturaAuthDomains = array( 'localhost', 'kgit.html5video.org', 'html5video.org', 'player.kaltura.com' );

MwEmbedSupport

git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/MwEmbedSupport.git
# MwEmbedSupport https://www.mediawiki.org/wiki/Extension:MwEmbedSupport
require_once "$IP/extensions/MwEmbedSupport/MwEmbedSupport.php";


TimedMediaHandler

apt-get install libav-tools ffmpeg2theora oggvideotools
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/TimedMediaHandler.git
# TimedMediaHandler https://www.mediawiki.org/wiki/Extension:TimedMediaHandler
// TimedMediaHandler is dependent on mwEmbedSupport 
// TimedMediaHandler
require_once( "$IP/extensions/TimedMediaHandler/TimedMediaHandler.php" );

This extension also requires schema changes, so run update.php after installing.

cd /var/www/html/wiki
php maintenance/update.php

Skins

Foreground

cd /var/www/html/wiki/skins
git clone https://github.com/thingles/foreground.git
# Foreground https://github.com/thingles/foreground
require_once "$IP/skins/foreground/foreground.php";









Deprecated (for memory)

Semantic Bundle

apt-get install zip p7zip-full
cd /var/www/html/wiki/extensions
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/SemanticBundle.git
make
cp SemanticBundle-20150409.tgz /var/www/html/wiki/extensions/
cd ..
tar xvf SemanticBundle-20150409.tgz
rm SemanticBundle-20150409.tgz
cd SemanticBundle/
cp SemanticBundleSettings.sample.php SemanticBundleSettings.php

Then, include SemanticBundleSettings.php and SemanticBundle.php within LocalSettings.php:

require_once( "$IP/extensions/SemanticBundle/SemanticBundleSettings.php" );
require_once( "$IP/extensions/SemanticBundle/SemanticBundle.php" );

The next step is to initialize Semantic MediaWiki. First, make sure that you are logged in as an administrator/sysop, such as the WikiSysop user. Then, go to Special:SMWAdmin, and click on the "Initialize or upgrade tables" button.

http://192.168.1.78/wiki/index.php/Special:SMWAdmin

After successful initialization, open up SemanticBundleSettings.php and uncomment the extensions you would like to use. It looks like :

note for myself : Semantic Tasks and Approved Revs seem to cause troubles (database)
  1. Cite error: Invalid <ref> tag; no text was provided for refs named base
  2. Cite error: Invalid <ref> tag; no text was provided for refs named comglob
  3. This is an optional step to take to assure that the semantic store is valid and up to date.
