Sgvizler has moved to github. This site and its repository will no longer be maintained.

OWLIM-Lite + Tomcat7 + Apache and Sgvizler

Thanks to Raoul Jean Pierre Bonnal for writing up this how-to.

Setup done on/with:

  • OSX 10.8
  • XCode
  • Homebrew: ruby -e "$(curl -fsSkL"
  • Ruby+RVM: \curl -L | bash -s stable --ruby
  • Git: bew install git


brew install tomcat


After you have downloaded and unpacked the archive, you must simply copy: openrdf-sesame.war and openrdf-workbench.war to /usr/local/Cellar/tomcat/7.0.29/libexec/webapps/ then open http://localhost:8080/openrdf-workbench/ to check if everything is working.

I suggest to install a Ruby gem gem install owlim-ruby Katayama san developed this gem to better interact with owlim, you can list, create, drop, import datasets to ontotext's triple store. Doc and source code here:


Apache 2.2 is already installed in OSX 10.8, the only problem is that there is no more GUI for configuration. We'll install a test web site under our home directory.

sudo vim /etc/apache2/users/yourusername.conf

Copy and paste text below:

<Directory "/Users/yourusername/Sites/">
Options Indexes MultiViews
AllowOverride All
Order allow,deny
Allow from all
<Location /openrdf-sesame >
ProxyPass http://localhost:8080/openrdf-sesame
ProxyPassReverse http://localhost:8080/openrdf-sesame

Location is needed to avoid Same origin policy as reported in official Sgvizler documentation and link below.

sudo apachectl (re)start

At this point you must copy your html page with your Sgvizler intallation in


and that's it

from terminal open /Users/yourusername/Sites/wonderfoul-charts-with-sgvizler.html
