SPARQL (pronounced "Sparkle") is a powerful query language to retrieve, modify and make the best use out of linked data. It is recognized as one of the key technologies of the semantic web due to its flexibility as well as ease of joining complex data structures and detecting intricate patterns in data. Its also the query language upon which the data.world platform is based.
