Breit-Pauli results for energy levels, lifetimes, and Lande g_J factors have been determined for all levels up to 2p²3d of the nitrogen-like sequence (Z=7-17) and 2p³3d of the oxygen-like sequence (Z=8-20). Exceptions are some lower members of the sequence where the spectrum included only those levels below the second 2p²4s term in the case of N-like or 2p³4s in the case of O-like. The computed energy and E1, E2, M1, M2 transition data between all levels, including convergence of the LS line strength for both length and velocity forms, may be viewed at a website. In this paper, critically evaluated transition data is presented for N I, O II, Mg VI, and Si VIII (N-like sequence) and O I, Ne III, Mg V, and Si VII (O-like) for E1 transitions including uncertainty estimates. The accuracy of energy levels is determined by comparison with experiment. Transition rates with uncertainties are compared with experiment and other theory.
