    With the current focus on the characteristics and effective operation of divertor configurations in fusion plasma research, a reassessment of the atomic database available for divertor modeling and diagnosis is taking place. The quest for ideal materials for divertor targets and for impurities that can be used to promote optimum working conditions has exposed some gaps in the database. In addition, for the finer spectroscopic diagnostic and modeling tools now being promoted, existing data may be organized inappropriately or may be at unsuitable precisions. In this paper, some examples that emphasize electron collisions and collisions with neutrals, are used to demonstrate these points. Then, a case study is presented, based on experience at SET Joint Undertaking, of tailoring atomic data and their manipulation for experiment support.
