Comunica Set Sources From Dataset Optimize Query Operation Actor

An Optimize Query Operation actor that appends the IRIs of the query's FROM and FROM NAMED clauses as sources to the context, and removes the dataset clauses from the query afterwards. IRIs from FROM NAMED clauses are tagged so that their data is exposed under the named graph of that IRI, while IRIs from FROM clauses are queried as regular sources.

This actor is only enabled when the dereferenceFromNamed context entry is set to true.

This module is part of the Comunica framework, and should only be used by developers that want to build their own query engine.
