I agree.    Unfortunately, when I looked at the title "RDF Layers" with
fresh eyes, I immediately thought of the SemWeb layer cake.  :-(   So, I
put in "Data", sometimes calling them "Data Layers" to help with that.

In the draft I currently have it flagged as an open issue, with some
other possibilities listed.  The one I woke up with this morning was
"spaces".   Conceptually it's close enough to tuple spaces that I think
the similarity in names would probably be okay.  (I just learned what
Linda was named after...!  Who knew...?)

(Downside to "space" is that is start with "s", so quads are (S,P,O,S)
which is annoying.)
