Quit Store – workspace for distributed collaborative Linked Data knowledge engineering ("Quads in Git"). RaiseWikibase – A tool for speeding up multilingual knowledge graph construction with Wikibase. RDF - Resource Description Framework, more commonly known as RDF, is a graph data model that formally describes the semantics, or meaning of information. It also represents metadata, that is, data about data.
