SPARQL (SPARQL Protocol and RDF Query Language) is a W3C Recommendation that provides a standardized query language for retrieving and manipulating data stored in Resource Description Framework (RDF) format. It includes a protocol for submitting queries and updates over HTTP, a JSON results format for SELECT and ASK queries, and a Graph Store HTTP Protocol for managing RDF graphs.
