In this excerpt, Taylor addresses the three tiers of Star Wars stories and how The Clone Wars fits into it.
"It’s funny, when we came in George said there are three things: ”There’s the father, the son and the holy ghost.” He said “There’s the father, who’s me, there’s the son who is through licensing and then there’s the holy ghost.” So when it’s authorized by George Lucas it’s canon. When it’s by “the son” — that’s the whole load of things made by the machine — and there is a lot of creativity there but it’s just not authored by George. The holy ghost is what fans provide and expect. So for us, we really have only one master to answer to. You’re not going to answer to the fans and nor would they want that, really."
That's about as clear as you can get: The Clone Wars writers are creating canon material and answering directly to the master, George himself.
