The tagged union of a blank node, a named resource, a
language-tagged literal, and a datatype-typed literal: the values admitted in the
object position of a Triple, whose subject and predicate positions admit narrower subsets. Every form carries
a kind discriminator, so a term is narrowed by testing that tag rather than by probing for properties, or read
with lexical without narrowing at all.
