Please note that below blogpost is based on my personal experience while developing which is the Sri Lanka’s Open Data Portal.

CKAN. In their words “the world’s leading open-source data portal platform”. Since you know about open data and how to use it let’s get right into CKAN. Oh oh! You don’t know about open data. Don’t worry! I got you covered. Read this blog post and you will get to know every thing you need to know about open data. Yeah trust me! Everything.

What’s CKAN?

As they say,

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.

Basically it’s a open source tool which allows you to manage your open data. It’s written in Python & uses Postgres as the database. If you are a MySQL fanboy and don’t know about Postgres don’t forget to read this blog post. It will give you a good idea about Postgres. Will divine into to CKAN’s features, so that you will know how powerful and feature-rich CKAN is. Brace yourself, here we go.

Installing CKAN

There are two ways to get it done. Links are provided to the docs.

  • Installing CKAN from package – LINK
  • Installing CKAN from source – LINK

Let’s talk about the second method. You will have to follow the steps as mentioned above in the url. It’s a comprehensive tutorial. Also below tips will help you to get the job done. Also check out the CKAN demo. You will get a pretty good idea about what you will have after installing CKAN.

  • Step 2 part b – It will talk few mins to initiate the download process. So give it sometime and wait. If not you can maually download from GitHub.
  • If jetty is not starting – edit /etc/default/jetty and change NO_START to be 0 (or comment it out). More info.

Depending on your environment you will come across different errors. Make sure to use Google or contact me here.
