"%META:TOPICPARENT{name=\"VOSIndex\"}%\n\n\n---+ Virtuoso SPARQL 1.1 Graph Store HTTP Protocol Support\n\n%TOC%\n\n---++What?\nAn application protocol for the distributing, updating and fetching of RDF graph content in a Graph Store via the mechanics of the [[http://www.w3.org/TR/sparql11-http-rdf-update/#rfc3987][Hypertext Transfer Protocol (HTTP)]] \n\n---++Why?\nSimplifies use of HTTP operations on RDF graphs which are managed outside of a SPARQL 1.1 graph store.\n\n---++How?\n \nVirtuoso supports /sparql-graph-crud/ Web Service Endpoint that implements the current draft of [[http://www.w3.org/TR/sparql11-http-rdf-update/][W3C SPARQL Graph Update protocol]]. Both /sparql and /sparql-graph-crud/ endpoints use the same SPARQL user account, so this user should be a member of SPARQL_UPDATE group in order to modify data via Graph Update protocol. \n\nNote that /sparql/ endpoint has /sparql-auth/ variant that uses web authentication. Similarly, /sparql-graph-crud/ has /sparql-graph-crud-auth/ variant. As soon as user is member of SPARQL_UPDATE group, he/she then can modify the stored data via /sparql-graph-crud-auth/ as well as via /sparql-auth/ .\n\n---+++Usage Examples\n\n * [[VirtGraphUpdateProtocolUI][Using sparql-graph-crud and sparql-graph-crud-auth Web Service Endpoints UI]] \n * [[VirtGraphProtocolCURLExamples][cURL examples]]\n\n\n---++Related \n\n * [[http://www.w3.org/TR/sparql11-http-rdf-update/][SPARQL 1.1 Graph Store HTTP Protocol]]\n * [[http://docs.openlinksw.com/virtuoso/rdfsparql.html#sparqloauthendpointauth][Virtuoso SPARQL Authentication]]\n" .
