Francois,
Thanks for your feedback and the question. Though I'm not sure what you
technically mean with 'my:links is a named graph' :) I think the answer
is simple: indeed we decided to model datasets and linksets
independently from each other. The following example from the (not yet
publicly available) voiD guide may illustrate this:
Let's assume the two well-known linked datasets DBpedia and DBLP:
:DBpedia void:containsLinks :DBpedia2DBLP .
:DBpedia2DBLP rdf:type void:Linkset ;
void:target :DBLP .
So, it is a linking *from* DBpedia *to* DBLP; as RDF is a direct graph,
this makes sense quite a lot (the subject 'sits' in DBpedia, the object
in DBLP).
IIRC, we had your option in mind as well [1] but decided to go for the
current modeling due to the above reasons. Actually, as I think, the two
modelings are equivalent, just with reversed directions:
YOUR model (if I got it right):
:dataset1 <- void:target - :links - void:target - > :dataset2
voiD model:
:dataset1 - void:containsLinks -> :links - void:target - > :dataset2
Cheers,
Michael
