That is the view I've held from the onset bearing in mind: 1. This is a non-issue for a combine Data Manipulation & Definition Language (DDL and DML) Language such as SPARQL which has support for Named Graphs 2. RDF is only a Data Definition Language which puts reification verbosity in the "it is what it is" box. Others in support of RDF* and SPARQL* : Of additional concern is the use of SPARQL* to propagate RDF* confusion into the SPARQL realm. By confusion, I am referring to the fact that syntax sugar (a stylistic preference) is being conflated with RDF as we know it and then propagated to SPARQL in the same manner, despite the fact that Named Graphs already provide an accepted solution. The fundamental issue at hand here is metadata handling. I've stumbled across a nice paper that covers a variety of RDF store approaches without introducing any of this RDF* and SPARQL* confusion [1].
