Federated variant of the SPARQL query language that enables federated
execution of queries across RDF data sources associated with SPARQL
endpoint (HTTP-based Web Service endpoint). Thus, given a number of
known SPARQL endpoints end-users and user agents are able to dispatch
SPARQL queries comprised of query patterns scoped to each endpoint.
