SPARUL, or SPARQL/Update, is a declarative data manipulation language that is an extension to the SPARQL query language standard. SPARUL provides the ability to insert, delete and update RDF data held within a triple store or quad store. SPARUL was originally written by Hewlett-Packard and has been used as the foundation for the current W3C recommendation entitled SPARQL 1.1 Update.
