Perhaps this particular class of literals is particularly prominent in SPARQL, but from my reading of the RDF Recommendation Set it doesn't actually occur all that often.

“Simple literal” vs “plain literal” isn't very clear naming.

Yes, I can see this as being very useful, and it would help throughout the specs. I often call exactly the same thing “RDF node” (because it's the kind of thing that can be a node in an RDF graph) and have a *slight* preference for that over “RDF term”.

In general, yes, for promoting a unified language across W3C specs.

Best,
