hi Lvc, yes, I had looked at this. I think that you can only have one type (or "class") of vertex from a single source file from the examples I've seen... is it possible to have more than joinfield name on an edge (so create an edge that joins on postid as well as some other attribute common to post and comment in your example) and supposing one wanted attributes in the json to be part of the edge (so more than one property per edge)... I guess I am looking for a more detailed example. ty, Sonu
