Hi Peter,
Thanks for sharing this. Layout-wise, the solution you present is not really
different from what Enhanced API does with regard to n-ary relationships. I
would like to know if there is an elegant creation pattern for n-ary
relationships, or do you have to rely on a manual creation of the proper
edge-node and role-relationships?
The query to extract information from the graph is however quite different from
what I am aiming for.
The back-operator is an interesting one and necessary in this situation,
whereas I would like to do a query like that without the use of a
back-operator. This is possible when the filter operator can take a traversal
of itself, something of the form filter(in("groupIn").name = "group2")
I think a traversal should in principal be performed with a query language that
is not turing complete so we can guarantee termination. This is especially
important in a REST architecture where we can't control the type of queries
asked.
