Abstract: BRASS is an international networking project for the development of a new public database providing accurate fundamental atomic data for stellar spectroscopic research. It rose from the fact that astrophysical parameters rely heavily on accuracy of atomic data which are scarcely provided throughout the literature and can suffer from systematic uncertainties. The ambition of the project is to provide carefully assessed atomic data in the range [4200-6800] Å by using high-resolution (R~80 000) and high signal-to-noise-ratio (S/N ~ 1000) spectra of BAFGK benchmark stars from the Mercator-HERMES and ESO-VLT-UVES spectrographs. The validated atomic datasets, combined with the observed and theoretical spectra are interactively offered online at brass.sdf.org.
