Large-scale self-consistent multiconfiguration Dirac--Hartree--Fock andrelativistic configuration interaction calculations are reported for the $n\leq 6$ levels in Be-like ions from B II to Ne VII. Effects from electroncorrelation are taken into account by means of large expansions in terms of abasis of configuration state functions, and a complete and accurate data set ofexcitation energies, lifetimes, wavelengths, and electric dipole, magneticdipole, electric quadrupole, and magnetic quadrupole line strengths, transitionrates, and oscillator strengths for these levels is provided for each ion.Comparisons are made with available experimental and theoretical results. Theuncertainty of excitation energies is assessed to be 0.01\% on average, whichmakes it possible to find and rule out misidentifications and aid new lineidentifications involving high-lying levels in astrophysical spectra. Thecomplete data set is also useful for modeling and diagnosing astrophysicalplasmas.
