That ws indeed my sense,  perhaps not the sense of some philosophers or
psychologists, but this is the RDF logic list, and this is the sense in
which RDF
uses it.

(In N3, if

:sky :color :blue  .

is the "sentence", then

{ :sky :color :blue }

is the "object".  In the RDF model, this is represented by a set of
sentences. which describe it.)

I obviously have gone to the wrong cocktail parties, not having seen the
word being used to impress the impressoinable ;-)
