Wikidata:Data donation – “This page is written for institutions, companies, organisations and individuals who are interested in adding data to Wikidata…Wikidata aims to create a multilingual free knowledge base about the world that can be read and edited by humans and machines alike. It provides data in all the languages of the Wikimedia projects, and allows for the central access to data in a similar vein as Wikimedia Commons does for multimedia files, it is also used by many other websites. The data on Wikidata is added by a community of volunteers both manually and by using software, much like other Wikimedia projects including Wikipedia. Wikidata has millions of items, each representing a human, a place, a painting, a concept, etc. Each item has statements (key-value pairs), each statement in turn consisting of a property such as “birth date”, and the appropriate value for the item. Likewise, there can be statements for external IDs, such as a VIAF identifier. Wikidata is hosted by the Wikimedia Foundation, a nonprofit charitable organization dedicated to encouraging the growth, development and distribution of free, multilingual, educational content, and to providing the full content of these wiki-based projects to the public free of charge.”
