The above features serve as an example of the data that can be archived in a AIF, which can be extended in future versions. For example, the intention of this initial version is to provide a digital archive of the presented primary data of an adsorption experiment ---the isotherm. As a result, it describes only basic information that is usually exported from adsorption instruments and a few convenient metadata items. The flexibility of this approach can be extended in future versions to include more detailed parameters that are not commonly presented, such as dead volume measurements and leak checks, or it could be combined with CIF data names for structural data to archive parallelized adsorptiondiffraction measurements.
