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)
