There needs to be a modifier to metatlas objects that allows identificaiton of values inferred from physical law or reference material vs measurement.  For example, the mz of a reference_mz is often based on the sum-formula +/- adduct.  In contrast, measured values, such as the mz of an uncharacterized feature, are based only on measurement.\r\n\r\nAnother example, would be a person injecting 10 nanomols of material and measuring an intensity of 1e5 counts.  One would expect that follow up observations of the same compound at 1e5 counts were also 10 nanomols. If a reference_intensity is from an authentic standard that is intentionally used as a reference vs an experimental sample where the reference_intensity is used as a placeholder for storing the extracted peak area for an ion.  Numerically, these approaches are identical, but conceptually, they are completely opposite.  We need to delineate which approach is intended for each assertion."}}
