Clarification on comparison to reified statements #274

Open RickMoynihan opened 1 year ago

RickMoynihan commented 1 year ago

The current draft spec states:

Unlike reified statements, RDF-star quoted triples are unique: wherever << :employee38 :jobTitle "Assistant Designer" >> appears, it always denotes one and the same thing. This impacts the modeling choices one has to make when using RDF-star; this is further discussed in § 2.3 Triples and occurrences.

It strikes me that this is possible with RDF reification, as blank nodes are not enforced by it e.g. one can do the following and unambiguously refer to :statement-1:

:statement-1 
     rdf:subject :employee38 ;
     rdf:predicate :jobTitle ;
     rdf:object  "Assistant Designer" .

In which case is the most meaningful difference simply that the reified statement is subject to entailment; where as in RDF-star the equivalent isn't?
