FAQ (v. 0.4)
Q: What does EMF-IncQuery call the 'name' of a graph pattern?
It is actually the fully qualified name, which is the fully qualified name of the containing machine, a separator dot, and the simple name in the pattern (the one you define it with after the pattern keyword). The fully qualified name of the machine, in turn, is the simple name of the machine, prefixed by the machine namespace (if any).
