 ## RDF Reader and Writer
 {JSON::LD} also acts as a normal RDF reader and writer, using the standard RDF.rb reader/writer interfaces:
 
     graph = RDF::Graph.load("etc/doap.jsonld", :format => :jsonld)
     graph.dump(:jsonld, :standard_prefixes => true)
 
+`RDF::GRAPH#dump` can also take a `:context` option to use a separately defined context
