Complete Instruction Set?

Hello there! I'm working on a gremlin to SQL implementation and was wondering if there is a specification of the "instruction set" language? E.g. wikipedia states that

g.V().as("a").out("knows").as("b").
  select("a","b").
    by("name").
    by("age")

g.V().as("a").out("knows").as("b").
  select("a","b").
    by("name").
    by("age")

is compiled to something which can be uniquely stringified into

[GraphStep([],vertex)@[a], VertexStep(OUT,[knows],vertex)@[b], SelectStep([a, b],[value(name), value(age)])]

[GraphStep([],vertex)@[a], VertexStep(OUT,[knows],vertex)@[b], SelectStep([a, b],[value(name), value(age)])]

and I was wondering if the later one is specified somewhere? Thanks in advance!
