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