+1

And my recommendation would be that the fourth component of 
a quad would be a graph name (which also would be optional).

Named graphs are a generic extension which can be very strongly
grounded in the RDF MT (since most of what you need is already
there), and provide for all of the other use cases employing
quads; and simply by defining the appropriate vocabularies.

In a sense, it's fair to argue that named graphs are not an
extension at all, since as resources, their definition is
central to the RDF MT, and any resource can be denoted by
URI, so if you're going to have quads rather than triples,
named graphs are the option which "extend" RDF the least.
