在Sparql中使用嵌套图

Question

I've seen some papers and some posts in here, like this one and this other one. I am wondering if it is possible to nest graphs in SPARQL and link them with edges like they were resource nodes with an URL. Thanks in advance

Answer 1

Named graphs provide the ability to link to a graph. This is not nest graph s- it's links from one graph to the concept of the other graph.
