Since we're discussing modifying T:DAB and Tardis:TARDIS, I'd also ask whether it's appropriate to modify T:NO RW in a relatively minor way for the sake of the proposed articles. Sometime like "if you are discussing something in N-space that when in the real world refers to something related to the making of the show itself, you can assume the bare minimum required to talk cogently about it in regards to Doctor Who (N-Space)". (if there's a way to get that less convoluted)
So for instance, because we saw "Big Finish", and we know that Big Finish refers to a producer of audio dramas IRL, we can say "Big Finish (N-Space) was an app on Osgood's computer, known for making audio dramas related to Doctor Who (N-Space)."
Since this is clearly the authorial intent, my worry is just wording this in a way to both make it understandable and not let in anything and everything.
