The background pressure of a vacuum system is one major limiting factor when it comes to the lifetime and coherence time of atomic quantum systems. Hence, potentially suitable materials for use in such experiments need to be assessed carefully regarding their outgassing behavior. To address this issue, we developed a strategy to identify, measure, and classify applicable materials, thereby assessing their suitability for use in UHV and XUHV environments. Identified materials, as well as subassemblies and commercially available parts, are then collected and indexed into a comprehensive database. We will present the prototype of this database in detail, including the outline structure and first results. We will demonstrate how standardization for the tabulation could work and which information is required to provide the data for even an inexperienced user, highlighting possible use cases and benefits for all types of vacuum-based experiments.
