/**
 * librdf_new_node_from_normalised_uri_string:
 * @world: redland world object
 * @uri_string: string representing a URI
 * @source_uri: source URI
 * @base_uri: base URI
 *
 * Constructor - create a new #librdf_node object from a URI string normalised to a new base URI.
 * 
 * Return value: a new #librdf_node object or NULL on failure
