# SPARQL Updates

[SPARQL 1.1 Update](https://www.w3.org/TR/sparql11-update/) is a [W3C ](https://www.w3.org)language to create and modify RDF graphs, thus including OWL ontologies.

The use of SPARQL updates asks for a SPARQL Endpoint, i.e. a server that can handle HTTP requests. SPARQL Endpoints are typically provided by [RDF stores](/vlft/kb/instantiation/datarepo/remote.md#rdf-store).

The full set of SPARQL updates is available in [this folder](https://github.com/difactory/repository/tree/main/sparql).
