Sure, but doesn't context determine role in this situation? Of course,
said determination might be implicit rather than explicit which is
ultimately inevitable. Thus, when _values_ are in the role of
representing the description of an observation subject, they denotation
"Data" applies. Likewise, if the aforementioned is achieved via a single
value, then the denotation "Datum" would apply.

Sure, but triples are an effective base upon which higher arity can be
built, right? (03)

Sure, but you always need a building point that provides foundation (be
permanent or temporary). (05)
