SPARQL (pronounced "sparkle", a recursive acronym [2] for SPARQL Protocol and RDF Query Language) is an RDF query language—that is, a semantic query language for databases—able to retrieve and manipulate data stored in Resource Description Framework (RDF) format.

SPARQL can be used to express queries across diverse data sources, whether the data is stored natively as RDF or viewed as RDF via middleware. SPARQL contains capabilities for querying required and optional graph patterns along with their conjunctions and disjunctions.

SPARQL (pronounced "sparkle") is a query language for the Semantic Web. It allows you to retrieve and manipulate data stored in RDF (Resource Description Framework) format, which is a standard for representing data on the Web.

Querying with SPARQL¶ Run a Query¶ The RDFLib comes with an implementation of the SPARQL 1.1 Query and SPARQL 1.1 Update query languages. Queries can be evaluated against a graph with the rdflib.graph.Graph.query() method, and updates with rdflib.graph.Graph.update(). The query method returns a rdflib.query.Result instance.

A SPARQL query is used to retrieve data from an RDF dataset. It consists of a set of patterns that match against the RDF data. The patterns are written in a syntax similar to SQL, but with some differences.

RDF and SPARQL are important because they provide a flexible way to represent and query data on the web. RDF provides a way to describe resources with a set of triples, while SPARQL provides a way to query and manipulate that data.

SPARQL is the standard query language for the Semantic Web and can be used to query over large volumes of RDF data. dotNetRDF provides support for querying both over local in-memory data using it's own SPARQL implementation and for querying remote data using SPARQL endpoints or through other stores SPARQL implementations.

SPARQL is the standard query language and protocol for Linked Open Data and RDF databases. Having been designed to query a great variety of data, it can efficiently extract information hidden in non-uniform data and stored in various formats and sources.
