This design space can be tricky, so having good concrete
examples is really valuable.

I wonder if dc:creator is a good use case. Does
its range include collections? A quick search
yields "An entity primarily responsible for making the resource."
not "an entity or list of entities...".


A common misconception is that

  <#paper> dc:creator ("Mark" "Steven" "Ralph").

somehow automatically corresponds to

  <#paper> dc:creator "Mark", "Steven", "Ralph".

so that "Mark" would get bound to ?who in
queries like
  SELECT ?who WHERE { <#paper> dc:creator ?who }.

This is not so.
