Schema Alignment

In OpenRefine, Schema Alignment is a process that transforms the tabular data in a project to the data format used by a knowledge base. A schema is a data structure that maps each row to a set of triples, statements or other records, depending on the target base. This functionality is provided by extensions or forks:

Knowledge base	Extension or fork	Documentation	OpenRefine version
Wikidata	Wikidata extension (part of OpenRefine)	Documentation	3.0+
Any RDF store	RDF extension	Documentation	2.6+
Freebase	Freebase extension (discontinued)	Documentation	2.0-2.6
GOKb	GOKb extension	Documentation	2.5+
GraphDB	OntoRefine	Documentation	2.7+
