This is actually a goal for any NeXus application definition.  A NeXus 
data file that is valid against the relevant application definition 
meets the structural criteria declared sufficient for interoperability.

Perhaps another measure of interoperability is the data content.  The 
data might be arranged in a NeXus data file with valid structure but 
useless content for the processing step (such as no valid range of data 
satisfying the Guinier approximation in small-angle scattering or no 
intensity peaks for powder diffraction analysis).  Standardization of 
data content or quality is not addressed by NeXus.
