New Query Language for Graph Databases to Become International Standard

That's a pretty vast question. Graph DBs and Relational DBs are obviously somewhat different, and therefore require different query semantics? As in: try querying SQL for "anything with an in-degree >= 4" without a four-way join.

Confused, why can't you just do something like this?

  SELECT name FROM user
  CROSS JOIN friend ON id2 = user.id
  GROUP BY id2 HAVING COUNT(id2) = 4

That can only query for a depth of 1. It doesn't let you query for friends of friends at an arbitrary depth.
