Evans et al. have, however, demonstrated how to convert the output files of three manufacturers' instruments plus the NIST-ISODB JSON format into a common format, the "adsorption information file" (AIF) that allows for machine-facilitated comparison of isotherms without extensive human intervention. The AIF format does not intend to include all possible metadata regarding an isotherm measurement, but enough to allow comparison of (ostensibly) equilibrium isotherms. The AIF format has been approved as an IUPAC Project, which will facilitate its development both for other manufacturers' instruments and generic isotherm data (which could include output of molecular simulations) as well as leverage and revise other IUPAC resources such as the IUPAC Gold Book. The development version of the AIF is available for use even prior to completion of the IUPAC project and we highly encourage that authors release their isotherm data in the AIF development format in the supplementary information of papers without delay.
