Hi Holger,

We have an opportunity to make RDF less confusing, and that's achieved
via clarity.

From my vantage point, here's the problem:

Just as we reached a point where RDF understanding was gaining traction,
along come both RDF* and SPARQL* to muddy the waters.

If there were no existing solutions to expressing metadata that
describes data depicted as a graph that would be one clear problem, but
that simply isn't the case [1].

How else does one describe the signage and surface combination delivered
by an RDF graph and the document from which it originates? All solutions
to this problem include some degree of verbosity if precision is the quest.

This is neither RDF nor SPARQL, so why not give it a different name and
spell out its syntax-sugar orientation clearly?
