title: RDF4J REST Repositories API
version: '10'
description: 'The RDF4J REST API is an HTTP protocol that covers a fully compliant implementation of the SPARQL 1.1 Protocol W3C Recommendation. This ensures that RDF4J Server functions as a fully standard-compliant SPARQL endpoint.
The RDF4J REST API additionally supports the SPARQL 1.1 Graph Store HTTP Protocol W3C Recommendation. The RDF4J REST API extends the W3C standards in several aspects, the most important of which is database transaction management.'
