OpenRefine is a free data-wrangling tool that can be used to process, manipulate, and clean tabular (spreadsheet) data and connect it with knowledge bases, including Wikidata and Wikimedia Commons.
This online course is available at any time, for free. Anyone with a Wikimedia account can enroll with the click of a button. It can be followed at your own pace, with computer-graded exercises. A certificate is awarded at the end to those who complete the course.
The training is suitable for Wikimedians, Wikimedia affiliate staff, and partners (e.g. GLAM staff and Wikimedians in Residence). Accomplishing the course should take an average of 6 to 8 hours.
This course was developed as part of the Wikimedia Foundation's
training and sustainability grant to OpenRefine. It is currently available in English and can be easily translated into other languages (more about the translation process
here and
here). Translations for this course in French, Spanish, and Portuguese are being worked on and will be available very soon.
Please, feel free to share this course with people you think might be interested in learning more about OpenRefine or Wikimedia Commons, who are part of your network, in groups, social media, or any other places.
