SemanticMediawikiInstall

This document details the installation of Semantic to the existing OSE Mediawiki.

Command line installation

1. Create the customized install script "composer.phar" by fetching the file "installer" and running it using php:

$ curl -sS https://getcomposer.org/installer | php

The above command failed with an error, so add "-d allow_url_fopen=On" to the php command, which succeeded:

$ curl -sS https://getcomposer.org/installer | php  -d allow_url_fopen=On
All settings correct for using Composer
Downloading...

Composer successfully installed to: /usr/home/osemain/composer.phar
Use it: php composer.phar
$ 

2. Move "composer.phar" into a directory in the PATH:

$ mv composer.phar ~/bin/.

3. Check the running version of Mediawiki using the "Special:Version" feature of Mediawiki:
