You need to install OpenRefine and download a data file to follow this lesson.
OpenRefine is a free, open-source Java application. You can download OpenRefine from http://openrefine.org/download.html. This lesson has been tested with all versions of OpenRefine up to the latest tested version, 3.4.1
Packages are available on https://openrefine.org/download.html for Windows, macOS, and Linux. Please download the latest stable version, choosing the "kit" for your operating system. Current versions of the "Windows kit with embedded Java" and "Mac kit" include everything you need to run OpenRefine. The "Linux kit" and traditional "Windows kit" require a "Java Runtime Environment" (JRE) installed on your system (see notes below).
If you are using an older version of OpenRefine, it is recommended you upgrade to the latest tested version.
Please follow the installation instructions in the OpenRefine User Manual: Installation Instructions
Notes:
- When you download OpenRefine for Windows or Linux from the address above, you are downloading an archive file (zip or tar). To install OpenRefine unzip the downloaded file to a permanent location on your computer. 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.
- The options "Windows kit with embedded Java" and "Mac kit" include Java as part of the package. You do not need to install Java if you use one of these kits. This is the preferred method on Windows and Mac systems.
- On Windows, if you use the traditional "Windows kit" without embedded Java, you will need a "Java Runtime Environment" (JRE) on your system. If you do not already have JRE or JDK installed, you can visit Adopt OpenJDK or Oracle Java to download an installer package. Please note that Oracle significantly changed their license terms in 2019 limiting it to "personal use" with out a paid license. If you use OpenRefine at work or in research, OpenJDK is preferred.
- On Linux a "Java Runtime Environment" (JRE) will be required to run OpenRefine. If you do not already have
JRE or JDK installed on your system, most distribution repositories will contain OpenJRE / OpenJDK packages. I
nstall the default version available from your distribution. For example, on Ubuntu/Debian:
sudo apt install default-jre
. - OpenRefine does not support Internet Explorer. Please use Firefox, Chrome or Safari instead.
You can download doaj-article-sample.csv, which is a csv file that will open in a new browser tab. Be sure to right click or control click in order to save the file (NOTE: In Safari, right click and select download linked file; in Chrome and Firefox, right click and select save link as...). Make a note of the location (i.e. the folder, your desktop) to which you save the file.
To exit OpenRefine, close all the browser tabs or windows, then navigate to the command line window. To close this window and ensure OpenRefine exits properly, hold down [control] and press [c] on your keyboard. This will save all changes to your projects.
If you encounter problems installing or running OpenRefine, a good source of support is the OpenRefine mailing list and user forum. Include your operating system when searching to find the most relevant answers for your issue, such as threads related to Windows, macOS, or Linux.
You may also want to check the Stack Overflow OpenRefine tag or the OpenRefine Gitter room.
