SPARQL 1.1 Uniform HTTP Protocol for Managing RDF Graphs

SPARQL provides a standard way to query RDF data. The SPARQL Update allows a user to update RDF graphs in a Graph Store at various levels of granularity, including individual RDF statements. The protocol described here is meant to provide a minimal set of uniform, colloquial HTTP operations for managing a semantic web of mutable, named RDF graphs at a strictly large level of granularity.
