+##### `put_rdfmap`
+
+Defines an external RDF map for lookup from a file or an HTTP(S) resource.
+As the RDF map is reducing RDF triples to a key/value map it is mandatory to set the target.
+The targeted RDF property can optionally be bound by an RDF language tag.

+put_rdfmap("<rdfResource>", "<rdfMapName>", target: "<rdfProperty>")

 ##### `put_var`
 
 Defines a single global variable that can be referenced with `$[<variableName>]`.
