canonical RDF graph representations

 The “The case for generating URIs by hashing RDF content” paper
 [1], dating back to 2002, mentions that “there is no current
 canonical serialization standard for RDF”.  (Then, they suggest
 their own canonical representation.)

 I wonder, has such a standard been since proposed?
