SPARQL Endpoint

This node establishes a connection to a SPARQL endpoint, which can reached with or without authentication, e.g. DBpedia. You can also find SPARQL endpoint repositories in the Internet such as the W3C SparqlEndpoints page or the availability monitoring page from the Vienna University.

Please notice that a couple of SPARQL endpoints do not accept deleting, updating or inserting queries; therefore Semantic Web nodes offering those functionalities won't necessarily work.

Functionality is provided using the Apache Jena Framework
