These input parameters have been added to the output Chemical JSON in order to make it easier to see what calculation parameters were used. The keys are common across the codes already present, but it is up to the driver script to decide how to interpret them. The "psi4" in the image name can be substituted with "nwchem" keeping all other arguments/JSON input the same and an NWChem calculation will be executed. Existing containers aim for consistency, but casting an eye to the future the platform will support the development of new methods, or the extension of existing containers beyond their current capabilities.
