I have not encountered any mention of the graph's reference or root node in any documentation or posts in this forum. Is it not significant? Are people not using it? I need to create node entities representing concept collections in my application directly related to the reference node so that when I use Neoclipse, I can drill down from the root node and not have to search for nodes using indexes. Is there a straightforward way to get a reference to the root node via annotations or arguments to the relatedTo annotation. Is this in the works?
