The absolute minimum information required for the standard analysis of small-angle scattering measurements is intensity as a function of scattering vector, \(I(\vec{Q})\).

- Allow for representation of
*reduced data*of any dimensionality- 1D SAS data
- 2D SAS data from detectors
- additional dimensions for complex experiments
*Q*can be either a vector (\(\vec{Q}\)) or a vector magnitude (\(|\vec{Q}|\))

- Identify and associate scanning axes
- Provide (when possible)
- uncertainties and their constituents
- masking information

- Allow for
- complex experiments with multiple detectors
- easy plotting of the data in close to their raw form

- Maintain the original dimensionality of the data if at all possible
- Use existing standards where possible or practical
