Wikidata is a free, collaborative, multilingual, secondary database, collecting structured data to provide support to anyone in the world. It is free in the sense that it allows the reuse of data in many different scenarios. You can copy, modify, distribute and perform the data, even for commercial purposes, without asking for permission. It is collaborative in the sense that Data is entered and maintained by Wikidata editors who decide on the rules of content creation and management. It is multilingual because data entered in any language is immediately available in all other languages. It is a secondary database because Wikidata records not just statements but also their sources and connections to other databases. And of course, it is structured data, so it can be queried by any programming interface.
This is a workshop that helps users learn to query data using SPARQL from wikidata and also contribute to its large data bank
