000003970 520__ $$aBRASS is an international research project for the development of a new public database providing accurate fundamental atomic data of vital importance for stellar spectroscopic research. The BRASS database offers atomic line data thoroughly tested by comparing theoretical and observed stellar spectra. We perform quality assessments of selected atomic input data using advanced radiative transfer spectrum synthesis calculations, which are compared to high-resolution Mercator-HERMES and ESO-VLT-UVES spectra of FGK benchmark stars observed with very high signal-to-noise ratios. We have retrieved about half a million atomic lines required for our detailed spectrum synthesis calculations from the literature and online databases such as VAMDC, NIST ASD, VALD3, CHIANTI, TIPBASE, TOPBASE, Spectr-W<SUP>3</SUP>, and SpectroWeb. The atomic datasets are cross-matched based on transition line electronic configuration information and organized in a new repository. We present an overview of new BRASS Data Interface developments allowing online user interaction for the combined spectrum and atomic data display, line identification, atomic data accuracy assessments, and line equivalent width measurements.
