 We explain how data donations to wiki data work This is Rachel. She works at a museum and loves her job because it means bringing knowledge to people However, the museum is limited to one city Shouldn't the knowledge collected in museums and archives be accessible to people all over the world? Rachel heard about wiki data a Multilingual free knowledge base that can be read and edited by humans and machines alike cool wiki data contains millions of items each representing different information a person a place or a piece of art The community of volunteers maintains this data, but the information has to be contributed Like many other galleries libraries and archives Rachel decides to contribute to wiki data First she collects cleans and prepares the data for digitizing Then Rachel talks to the contributors of wiki data that take care of data uploads With their help Rachel can now add her museum's treasure chest of data to wiki data Data shared in wiki data becomes free knowledge released into the public domain Others can query wiki data and build upon it wiki data is used by the wiki media projects such as wikipedia and also by many other websites and applications Like a mobile app that can give information on pieces of art around the user Because Rachel likes to see the different ways her uploaded data is used She regularly checks the data and updates it if necessary Rachel is happy the knowledge that her museum offers is now available worldwide in almost 300 languages ready to be used by anyone By donating data to wiki data She has helped to give more people more access to more knowledge The museum is now much larger than the city it is located in If you also want to learn how to contribute and donate your data visit wmde.org data donation
