Pursuing a random theory on the identity of Artemis, (but not asking because there wouldn't be any fun in that)...

Is Artemis her actual name or a code name separate from that?
Is Artemis the name she appeared with in print?
If it is a code name or a replacement name of the print name, is there a clear connection, even equivalency, between her real or original name and code name?

(Problem with trying to match up an obscure character in the DCU is that I don't actually know much about my obscure candidate. I'm basically going on who is pictured holding a bow and arrow and is drawn looking halfway Asian.)
