Is RDFn the same as RDF-star? Well, in the sense that each can encode the other, yes. But this isn't a very useful sense of sameness. More interesting is whether there is a natural correspondence between all of RDFn and all of RDF-star. But there isn't, at least so far as I can ascertain from the information given to the working group. RDF-star has unasserted triples, which RDFn appears to lack. RDFn uses graphs with multi-edges, which RDF-star does not provide. peter On 11/26/23 22:08, Souripriya Das wrote: > Since I did not hear any comments on RDFn during the first half of our last > meeting that I was able to attend (except, maybe, Gregg might have said > something right at the beginning but I had audio issues on my side), I thought > it may be helpful to mention below a few high-level points about RDFn and how > it is related to RDF-star concepts and syntax: ("statement" here simply means > "a triple or quad"): > > 1) RDFn = RDF-star (which, I think, uses implicit naming in some sense, with > << s p o >> as the name) + explicit naming (using IRIs as custom names). > > 2) RDFn (with appropriate syntactic shortcut) would appear exactly the same as > RDF-star to a user who does not use multi-edges or statement-sets. > > 3) RDFn does not change anything regarding how users work with default graph > and named graphs today. > > 4) RDFn requires use of explicit naming if user needs to store multi-edges. > For modeling multi-edges, user does not need to introduce new triples or quads > with special properties like :isOccurrenceOf or :hasOccurrence. > > 5) RDFn requires use of explicit naming for modeling statement-sets as well.
