Open Data Node v1.1.1 was released  . It consist of following versions of components:

Debian packages are available at:

Installation manual for ODN using Debian package (odn-simple):

List of issues included in the release is available:

Installation manual

Upgrade from ODN prior to 1.0.0 is not correctly supported due to change of CKAN version and also infrastructure changes.

Upgrade from ODN v1.0.X is supported but it is strongly recommended to backup databases.

Supported distribution is Debian Wheezy (7.x).

To install (or upgrade to newer version of ODN) packages from COMSODE Debian repository, please follow these steps:

  1. Configure Debian as follows:

    1. if FQDN is defined, the host has to be visible from external network, (e.g. if FQDN is then the host must be visible both through http and https via and 

    2. if FQDN is not defined, the host has to be visible from external network, (e.g. if hostname is example then the host must be visible both through http and https via http://example and https://example

      How to set FQDN 

      # get ip address of host
      IP_ADDRESS=`/sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'`
      # set FQDN - where host is accessible via 
      echo "$IP_ADDRESS my-computer " >> /etc/hosts
      # verify 
      hostname -A



  2. Add ODN packages repository into apt-sources-list: 

    echo "deb wheezy main" > /etc/apt/sources.list.d/odn.list
  3. Add ODN public key: 

    wget -O - | apt-key add -
  4. Update apt sources: 

    aptitude update
  5. Use either option a for new installation of ODN or option b for upgrade to newer version of ODN:

    1. install ODN box: 

      aptitude install odn-simple
    2. upgrade ODN box: 

      aptitude upgrade

The following user input is required during the installation process (in case of ODN upgrade, previously provided values are used = no user input is required):

  • ldap password: whatever password can be used
  • Virtuoso password: dba


In case of ODN upgrade, user is required to confirm replacement of configuration files from previous installation

  • it should be confirmed by pressing y each time user input is required


If you want to reduce packages that are not necessary, then call
aptitude install --without-recommends odn-simple

URLs of components

After successful installation the following URLs are assigned: 

  • ODN/PublicCatalog
    • http://<hostname>/
    • https://<hostname>/
  • ODN/InternalCatalog: https://<hostname>/internalcatalog
  • ODN/UnifiedViews: https://<hostname>/unifiedviews
  • ODN/midPoint: https://<hostname>/midpoint/login
  • ODN/cas: https://<hostname>/cas

Only public catalog is accessible also via http protocol, other services are accessible only via https due to the fact that there is transfer sensitive information.


Default users

After successful installation the following users are created (can be used immediately): (warning) TODO correction needed


UsernamePasswordRole in componentODN roleNote
ODN casadminPassw0rd  user used in other components, logged in via ODN/CAS
ODN/midpointsee ODNsee ODN ODN userlogin to idm through cas

upload dumps to /var/www/dump - DPU: uv-l-filesUpload can upload dumps. Dumps are accessible via https://host/dump/

upload graphs to /var/cache/virtuoso/upload - DPU: uv-l-filesToVirtuoso can upload graphs from the path to virtuoso


casadmin is used as standard user to work with OpenDataNode. Further users can be created in midpoint.

(warning)You are strongly advised to change passwords right after installation.

Known issues



Java 7 support

tomcat 7 uses by default java 6 so it is necessary to change default java for tomcat. Edit /etc/default/tomcat7, update environment variable JAVA_HOME.


Python dependency update (in case of ODN upgrade no Python dependency update is needed)

In case of fresh clean Debian Wheezy installation the steps described above should work, no other commands are required. However in some cases some python dependency problems has been detected (when the Debian environment was created as a result of virtualization). 

In such cases the following steps are required to resolve the dependency problems:

apt-get purge python\*
apt-get install python2.7-minimal  -V
apt-get install libapache2-mod-wsgi -V
apt-get install lsb-release  -V
apt-get install python-pkg-resources  -V
apt-get install python-pip  -V
apt-get install python-setuptools  -V
aptitude install odn-simple -V
