We are providing a tabular overview (Table in supplementary material ZIP file) to document the complete mapping of how the steps of the practical execution of a reaction in XDL correspond to Reaction SPL. Essentially XDL allows sequences of "steps" directly mapped to the SPL "processStep" element. In the XDL XML format, the process step names are the XML element names such as: Add, Transfer, FilterThrough, Stir, HeatChill, Dissolve, CleanVessel, Precipitate, Crystallize, EvacuateAndRefill, Purge, Filter, WashSolid, Dry, Separate, Evaporate, and Irradiate.
