You need to download and install OpenRefine and download a data file to follow this lesson.
You can download OpenRefine from http://openrefine.org/download.html. This lesson has been tested with all versions of OpenRefine, from 2.8 to 3.1.
OpenRefine 3.1 is recommended.
There are versions for Windows, Mac OS X and Linux.
When you download OpenRefine for Windows or Linux from the address above, you are downloading a zip file. To install OpenRefine you simply unzip the downloaded file wherever you want to install the program. This can be to a personal directory or to an applications or software directory - OpenRefine should run wherever you put the unzipped folder. The location has to be a “local” drive as problems have been reported trying to run OpenRefine from a Network drive.
If you are downloading OpenRefine for Mac, you are downloading a ‘dmg’ (disk image) file which you can open, and then drag the OpenRefine application to an appropriate folder on you computer.
OpenRefine is a Java application, and you need to have a ‘Java Runtime Environment’ (JRE) installed on your computer to run OpenRefine. If you don’t already have one installed then you can download and install from http://java.com by going to the site and clicking “Free Java Download”.
To run Refine:
The interface to OpenRefine is accessed via a web browser. When you run Refine normally this should open a window in your default web browser pointing at the address http://127.0.0.1:3333. If this doesn’t happen automatically you can open a web browser and type in this address.
If you encounter problems installing or running OpenRefine, a good source of support is the OpenRefine mailing list and forum
If you are installing OpenRefine on Windows, you may want to check the thread on Installing OpenRefine on Windows 7
