CKAN

Introduction

According to the CKAN webpage:

CKAN is a powerful data management system that makes data accessible – by providing tools to streamline publishing, sharing, finding and using data. CKAN is aimed at data publishers (national and regional governments, companies and organizations) wanting to make their data open and available.

In order to manage the datasets of the web index project, CKAN is considered as an option. In this page, the experiences with CKAN will be documented.

Installation

In order to get CKAN installed, a virtual machine with Ubuntu 12.04 has been created and then, this tutorial has been followed. There are some considerations not indicated in the tutorials that have to be keep in mind.

• When setting up SOLR, in the configuration file (/etc/default/jetty), the JETTY_HOST line indicates which hosts can access the SOLR server, 127.0.0.1 is the production configuration, however, for testing purposes, it has to be accesible to the host, so it was made globally accesible selecting the IP 0.0.0.0.

• In order to create the file production.ini, first a development.ini file has been created, to do so, it is needed to run first the following commands:

sudo apt-get install python-pastescript python-pip
pip install pylons
paster make-config ckan /etc/ckan/default/development.ini

Then, the development.ini file has been copied and pasted as production.ini and over this file the sqlalchemy.url has been edited to fit our database installation, probably more edition has to be done in order to improve the production configuration.

#Post installation setup The Post installation setup tutorial has been followed. Again there are some considerations:

• The note that appears in the top of the tutorial applies even thought the selected installation was the Option 1.
