Building on results from the Magnetism in Massive Stars (MiMeS) project, this paper shows how a two-parameter classification of massive-star magnetospheres in terms of the magnetic wind confinement (which sets the Alfven radius R-A) and stellar rotation (which sets the Kepler co-rotation radius R-K) provides a useful organization of both observational signatures and theoretical predictions. We compile the first comprehensive study of inferred and observed values for relevant stellar and magnetic parameters of 64 confirmed magnetic OB stars with T-eff greater than or similar to 16 kK. Using these parameters, we locate the stars in the magnetic confinement-rotation diagram, a log-log plot of R-K versus R-A.
