It assigns (or renames) the blank node IDs when they are added to the
graph (librdf_model) which does happen when they are read from a
file, URI or whatever.

If you use pseudocode
   statement=new Statement( new BlankNode(), new URINode(), new URINode() )
you get a new statement with a newly invented blank node identifier
at that point.
