Wikidata 101: An Introduction


About this course

Wikidata is emerging as a pivotal hub in the web of data. It contains over 110 million Items and is currently the most active of all the Wikimedia projects. However, contributing to Wikidata can be challenging for beginners. This course guides learners through 5 chapters, exploring the knowledgebase, queries, open data, and the semantic web. You'll gain insight into Wikidata's operations and foundational principles before diving into making your first contributions.

You will learn how to create new Items on Wikidata, determine which topics are allowed on Wikidata, and understand measures taken to ensure data quality. Additionally, you'll explore how to reuse data from Wikidata and engage with a community of several thousand volunteers.

The first edition of this English version of the MOOC took place in April 2024. Learn more about the course description, content, and schedule for future iterations at Wikidata:Open Online Course.


This MOOC was originally developed in French by Wikimedia France with financial support from Wikimedia Deutschland (WMDE). It was later updated and translated into English by WMDE's software communication team.
